If the controller is already installed, remove the controller from its installed location to remove the cover. Take all the precautions for the initial installation of the controller. Configuring the BACnet Communication Card Figure 27: BACnet Communication Card 32 FX14 Field Controller Technical Bulletin

33 To install the BACnet communication card: 1. Remove power from the FX14 (hot plug-in not allowed) and isolate all high voltage connections to the FX Remove the cover of the FX14. This normally requires that you remove the controller from its permanently installed location. IMPORTANT: The Complementary Metal Oxide Semiconductor (CMOS) integrated circuits in the controller and on the communication card are sensitive to static voltage discharges. Take suitable precautions. 3. Fit the two stand-offs supplied with the BACnet card into the FX14 printed wiring board. 4. Press the BACnet card connector pins into the communication board connector on the FX14 board. Make sure all of the pins are correctly seated in the connector. 5. Press the card onto the stand-offs to secure the card firmly in position. DIP Switch Settings The BACnet MS/TP Communication Card features two 8-position DIP switches labeled S1 and S2. These switches allow you to: configure the card for BACnet operation determine the method used to select the BACnet MAC address and baud rate set the BACnet Media Access Control (MAC) address and baud rate set the BACnet MS/TP Bus Number Configuring the Card for BACnet Operation Use switch 5 of S2 to configure the card for BACnet operation. Set S2 switch 5 to ON (1) for BACnet operation. Determining the BACnet Baud Rate and MAC Address Selection Method You can use either the DIP switches or the FX14 s integral user interface to select the BACnet baud rate and MAC address. Use switch 1 of S2 to determine the preferred method as follows: To use the DIP switches to set the BACnet baud rate and MAC address, set switch 1 of S2 to OFF (0). To set the baud rate and MAC address via the DIP switches, see Setting the BACnet Baud Rate. FX14 Field Controller Technical Bulletin 33

34 To use the FX14 s integral user interface to set the BACnet baud rate and MAC address, set switch 1 of S2 to ON (1). To set the baud rate and MAC address via the integral user interface, see Setup Menu - N2/BACnet Baud Rate and N2/BACnet Address Selection. Setting the BACnet Baud Rate To set the BACnet baud rate, you use switches 4, 3, and 2 of S2 as shown in Table 8. Table 8: S2 Switch Settings for Baud Rate S2 Switch Baud Rate OFF (0) OFF (0) OFF (0) 9600 (default) OFF (0) OFF (0) ON (1) 19,200 OFF (0) ON (1) OFF (0) 38,400 OFF (0) ON (1) ON (1) 76,800 Note: For BACnet MS/TP communication with a Metasys or Facility Explorer supervisory system, we recommend you select 38,400 baud rate. IMPORTANT: If you change the BACnet baud rate with power applied to the FX14, you must cycle the power for the new baud rate to become active. Setting the BACnet MAC Address To set the BACnet MAC address, you use the seven switches of S1 to represent the binary format of the BACnet MAC address (Table 9). Table 9: S1 Switches for BACnet MAC Addressing S1 Switch Switch ON Value The BACnet MAC address equals the sum of S1 switches ON values. For example, if the first (1), the third (4), and the fifth (16) DIP switches are set to ON (1), then the FX14 s BACnet MAC address is 21 ( = 21). Note: Addresses 0 to 3 on the field bus network of a Metasys Network Automation Engine (NAE) or Network Control Engine (NCE) controller are reserved for specific supervisory functions. IMPORTANT: If you change the BACnet MAC Address with power applied to the FX14, you must cycle the power for the new address to become active. 34 FX14 Field Controller Technical Bulletin

35 Setting the BACnet MS/TP Bus Number In a BACnet network, every device must have a unique Device Object Identifier (ID). The FX14 controller automatically calculates its Device Object ID as follows: Device Object ID = (MS/TP Bus Number*1000) + MAC Address For example: an FX14 controller with an MS/TP Bus Number of 15 and a MAC Address of 65 has a Device Object ID of Whenever you have more than one MS/TP Bus in your BACnet network, you must set the MS/TP Bus Number to something other than 0. To set the BACnet MS/TP Bus Number, you use switch 8 of S1 and switches 8, 7, and 6 of S2 to represent the binary format of the MS/TP Bus Number (Table 10). Table 10: S1 and S2 Switch Settings for BACnet MS/TP Bus Numbering S1 Switch S2 Switch Switch ON Value The BACnet MS/TP Bus Number equals the sum of the ON values for switch 8 of S1 and switches 8, 7, and 6 of S2. For example, if switch 8 of S1 and switches 8 and 6 of S2 are ON, then the FX14 s BACnet MS/TP Bus Number is 13 ( = 13). Note: The MS/TP Bus Number is only used to set a unique BACnet Device Object ID. This number is not necessarily the same as the Network ID that may be required for the Ethernet-to-MS/TP Router to connect the MS/TP bus to an Ethernet network. IMPORTANT: If you change the BACnet MS/TP Bus Number with power applied to the FX14, you must cycle the power for the new Bus Number to become active. FX14 Field Controller Technical Bulletin 35

36 Connecting the BACnet Communication Card The FX14 controller cover indicates the Supervisory Link terminals as 1, 2, and 3. For the BACnet communication card, you can make the connections to the RS-485 MS/TP Bus according to Table 11. The connections are polarity sensitive; therefore, you must make the correct connections. If the BACnet MS/TP bus cable has a shield, you need to twist or connect the shields of the incoming and outgoing cables and insulate the exposed metal wires with tape. If the shield is used as the COM wire, connect it to Terminal 1.

41 NRM Series of Network Room Modules You can use the Network Room Module (NRM) with LCD display with the FX14 controller. The LCD display, along with the dial and push button on the front of the module, allows you to view the room temperature, view and adjust the setpoint temperature in the controller, and manually override the automatic fan speed control operation. On models available in North America, you can toggle temperature units between F and C. When you move the dial or press a button, a temporary occupied (bypass) mode is requested during unoccupied mode (night/weekend) operation. The unoccupied mode may appear by a flashing LCD display. Figure 31: NRM Room Command Modules (80 x 80 mm [3.15 x 3.15 in.]) Figure 32: NRM Room Command Modules (120 x 80 mm [4.72 x 3.15 in.]) (North American Model) The NRM Network Room Module connects to the Remote Display terminals (local link bus) of the FX14 controller. The room command module accepts a power supply of 15 to 24 VDC or 24 VAC. Refer to the Network Room Module Technical Bulletin (LIT ) for details about the physical connections required between the room command module and the FX14 controller, and for details about the features and functions.

(North American Model) Mounting and Wiring the Room Command Modules The TM-2100 or NRM Room Command Module is designed for wall mounting. You should place the module where occupants can easily read and adjust the setpoint dial or fan speed override switch. You should also place the module where the temperature is representative of the general room conditions. Avoid cold or warm air drafts, radiant heat, and direct sunlight. Before you connect or disconnect any wires, ensure that all power supplies are turned off and all wires are potential-free to prevent equipment damage and avoid electric shock. Terminations are made on the terminal blocks in the base of the module, which accept one 1.5 mm 2 (16 AWG) wire or two 0.8 mm (20 AWG) wires. All wiring to the module is at Safety Extra-Low Voltage (SELV in Europe, Class 2 in North America) and must be separated from power line voltage wiring. Do not run wiring close to transformers or high frequency generating equipment. Complete and verify all wiring connections before applying power to the controller to which the module is connected. FX14 Field Controller Technical Bulletin 43

44 Remote User Interface In addition to the optional integral user display, the FX14 can support one MUI display. The MUI is available in two models: panel mount (up to 3 m [9.8 ft]) and wall mount (up to 300 m [1,000 ft]). For the panel mount connection, use the pre-cabled connection kit (LP-KIT C), 3 m (9.8 ft) long, with a phone jack on the MUI side and a preassembled screw connector on the FX14 side.

48 Inputs and Outputs Introduction The FX14 Controller features the following physical I/O channels. You can directly connect up to 29 physical inputs and outputs to the FX14, including the following: six Analog Inputs twelve Digital (Binary) Inputs nine Digital (Binary) Outputs two Analog Outputs 48 FX14 Field Controller Technical Bulletin

49 Inputs and Outputs Concepts Analog Inputs The FX14 controller accepts up to six analog inputs. You can configure each one, via FX Builder and jumper configurations, to read: A99 NTC 10k PT1000 Ni1000 passive temperature inputs Ratiometric ( V) or 0-10 V active inputs Digital Inputs The FX14 accepts twelve digital (binary) inputs from voltage free contacts. With the input filter set at 50 Hz, you can configure a transition counter (minimum 10 ms ON and minimum 10 ms OFF) in the control application for any one or more of the digital inputs. Analog Outputs The FX14 provides two analog outputs: 0-10 VDC at 3 ma Pulse Width Modulation Signal (PWM) at 100 Hz cycle frequency with a 15 VDC/10 ma reference signal Analog Outputs are configured by application software and jumper configurations. Digital Outputs The FX14 provides nine digital outputs, available in two hardware configurations: nine relays, or five relays and four triacs. FX14 Field Controller Technical Bulletin 49

50 Detailed Inputs and Outputs Procedures Analog Inputs You can configure the six FX14 analog inputs to accept a wide range of input signals, either passive or active. The FX14 provides a jumper configurable (Terminal 3, 8, 13) Voltage Reference signal for active analog input for either Ratiometric or 0-10 V sensors. See Jumper Details. The Voltage Reference outputs can supply 16 VDC (20 ma) for 0-10 V Sensors or, alternatively, 5 V (15 ma) for ratiometric sensors. In total, the three output terminals can supply 20 ma maximum. This supply limits the number of active sensors powered by the controller. Check the sensor current consumption data before you connect any device. Figure 39: Analog Input Connection Diagram The ranges of active sensor (voltage) inputs are set using configuration parameters within the application software. These parameters, HighRange and LowRange, define the equivalent values for reading at high (10 V, 4.5 V) and low (0 V, 0.5 V) signal inputs. Voltage inputs from differential pressure transducers can be linearized by a square root function (SQRT), which operates over the complete range of the input. The passive sensor (resistance) inputs have pre-configured linearization characteristics within the application software. For these sensors, the measurement range is fixed, but you can set the reliability range in the software. 50 FX14 Field Controller Technical Bulletin

51 The input signal is converted by the FX14 according to the related Analog Input object setup configuration. The setup possibilities include the following: A99 Johnson Controls temperature sensor Ni1000 ohm Nickel (Ni) temperature sensor Pt1000 ohm Platinum (Pt) temperature sensor NTC 10k ohm temperature sensor linear 0-10 V ratiometric sensor V The measurement unit is also configurable to enable the controller to propagate the measured value via the network in the appropriate format. (This scenario is particularly important for LONWORKS networks.) Available configurable units include the following: Temperature Percentage Air Pressure Liquid Pressure Flow Voltage A configurable filter constant in seconds is available in the FX14 application software for each analog input for the reduction of signal instability. You can configure an additional anti-spike filter to limit the rate of change of the input value. FX14 Field Controller Technical Bulletin 51

52 Connecting Passive Resistive Sensors The FX14 controller provides the power source and linearizes the signals from Resistive Temperature Device (RTD) sensors connected to analog inputs to provide a reading in temperature units. The analog input must be configured to accept the correct passive sensor type in the control application software loaded into the FX14 controller. Figure 40 shows a Johnson Controls A99 probe wiring diagram. The resistive sensors have to be connected in the same way. Figure 40: A99 Resistive Sensor Connection Diagram IMPORTANT: The two resistive probe leads are the same, in that they have no polarity; therefore, it is not necessary to respect any specific order when connecting to the terminal block. 52 FX14 Field Controller Technical Bulletin

53 Connecting Active 0-10 V Sensors The FX14 can accept active temperature, pressure, flow, and humidity sensors that provide voltage signals. Figure 41 shows the connection between an FX14 and a Johnson Controls HT D1 humidity and temperature sensor powered by the FX14 controller at 16 VDC. Figure 41: Active 0-10 V Probe, Connection Diagram You must configure the analog inputs to accept 0-10 V signals in the control application software loaded into the FX14 and the Analog Input Sensor Power Supply jumpers must be set 1-2 for 16 VDC (Table 18). Table 18: Active 0-10 V Sensors FX14 Terminals HT-9001 Terminals Description 1 - AI Com A Common Reference 3 - AI V Ref C Sensor Power Supply 16 V, 20 ma 2 - AI1 B Humidity Output 0-10 V 5 - AI2 Bt Temperature Output 0-10 V FX14 Field Controller Technical Bulletin 53

54 Connecting Active Sensors Powered by 24 VAC The FX14 can accept active temperature, pressure, flow, and humidity sensors that provide voltage signals and are powered by 24 VAC. If the 24 VAC power supply of the sensor is not isolated from the sensor output signal, then use a separate transformer powering only the active sensor to maintain the isolation of the analog input and the microprocessor from the power supply. See Figure 42 and Table 19. Figure 42: Active Sensor Powered at 24 VAC Connection Diagram Table 19: Active Sensors Powered by 24 VAC FX14 Terminals Sensor Cable Description 1 - AI Com Green Common Reference 2 - AI1 White Signal Output IMPORTANT: Respect connection polarities when wiring multiple sensors. Powering an active sensor with the same 24 VAC power supply as the FX14 Field Controller may affect the isolation between the microprocessor and the power supply. If you disregard the power supply and analog input polarity, a short circuit may result, causing the external fuse to blow. 54 FX14 Field Controller Technical Bulletin

55 Digital Inputs The FX14 controller accepts twelve digital (binary) inputs from voltage free contacts. Note: There are four common terminals (DI Com) for all twelve digital inputs. The Digital Input objects in the application software provide the interface between the hardware digital input channels and the control logic. A digital input is active depending on its polarity setting. The default setting is Normally Open or Direct, which means that the input is active (true) when the contact is closed. Connecting Voltage-Free Contacts to Digital Inputs The voltage-free contacts are connected to the controller as shown in Figure 43. Digital Input Connections are shown in Table 20. Figure 43: Connecting Voltage Free Contacts FX14 Field Controller Technical Bulletin 55

56 Table 20: FX14 Digital Input Connections FX14 Terminals Description 21 - DI Com Common Reference, Voltage-Free contacts 22 - DI1 Digital Input 1, Voltage-Free contact 23 - DI2 Digital Input 2, Voltage-Free contact 24 - DI3 Digital Input 3, Voltage-Free contact 25 - DI Com Common Reference, Voltage-Free contacts 26 - DI4 Digital Input 4, Voltage-Free contact 27 - DI5 Digital Input 5, Voltage-Free contact 28 - DI6 Digital Input 6, Voltage-Free contact 29 - DI Com Common Reference, Voltage-Free contacts 30 - DI7 Digital Input 7, Voltage-Free contact 31 - DI8 Digital Input 8, Voltage-Free contact 32 - DI9 Digital Input 9, Voltage-Free contact 33 - DI Com Common Reference, Voltage-Free contacts 34 - DI10 Digital Input 10, Voltage-Free contact 35 - DI11 Digital Input 11, Voltage-Free contact 36 - DI12 Digital Input 12, Voltage-Free contact Using Analog Inputs as Digital Inputs If you need more than 12 available digital inputs, the FX16 Master Controller allows you to use an analog input as digital input. Figure 44: Digital Input Connection A 1k ohm resistor must connect to the analog input terminals to prevent instability in the sensitive circuits from electrical disturbances on the wiring. You need to configure the analog input as an A99 input in FX Builder. The digital signal is derived from the Reliability attribute of the analog input object. An open contact gives a Normal status and a closed contact gives an Unreliable Low status. 56 FX14 Field Controller Technical Bulletin

57 Connecting the Transition Counter Input The FX14 features one transition counter input on one or more of the digital inputs. The transition counter imputer samples a pulse signal at 50 Hz, with a minimum ON time of 10 ms and a minimum OFF time of 10 ms. The Input Counter object in the application software provides the interface between the digital input, acting as a transition counter, and the control application. The totalized value is stored in nonvolatile memory during a power interruption to the FX14 controller and retrieved by the object after power restoration. Any pulses during the power interruption are not counted. For example, the transition counter counts the number of times an item of equipment is started. For informational purposes and energy management, you can also use the transition counter can as a totalizer for energy consumption measurement. For primary energy billing applications, a separate utility meter approved by local authorities is normally required. FX14 Field Controller Technical Bulletin 57

58 Analog Outputs The FX14 controller provides two analog outputs you can configure as 0-10 VDC (each at 3 ma maximum) or PWM at 100 Hz. The Analog Output objects provide the interface between the two hardware Analog Output channels and the control application. See Figure 45. Figure 45: Analog Output Connection Diagram You can configure the analog outputs for direct or reverse acting in the application software. You can limit by high limit (MaxOutput) and low limit (MinOutput) values. 58 FX14 Field Controller Technical Bulletin

59 Connecting the 0-10V Analog Output Use the FX14 analog outputs to drive proportional devices and connect the analog outputs to drive any of the Johnson Controls proportional valve actuators. See Figure VA Figure 46: Connecting the Analog Output IMPORTANT: When the power supply to the actuating device uses the same common terminal or connection on the device as the analog output, respect the same power supply connection polarity at any other device connected to the FX14 controller. Connecting AO Com to 24 V Com leads to the loss of the isolation of the microprocessor in the FX14. Not respecting the power supply polarity may result in a short circuit in the power supply. Table 21: Connecting the Analog Output FX14 Terminals Description 73 - AO1 Com Common Reference 72 - AO1 Analog Output 0-10 V 82 - AO V~ Com Common Reference 83 - AO V~ Hot Power Supply 24 VAC FX14 Field Controller Technical Bulletin 59

60 Connecting the PWM Analog Output The PWM configuration of the FX14 Analog Outputs gives additional flexibility and capability to drive and command also fan speed controller, such as the U215LP-PWM Series. Connecting a Fan Speed Controller with Opto-isolated PWM Input If the PWM Input of a fan speed controller is opto-isolated, the FX14 provides a voltage reference signal on Terminal 71 and 74 to power the input. The AO Voltage Reference (AO V Ref) signal supplies 15 VDC 10 ma (maximum) needed to polarize the opto-isolated PWM input of the connected load. See Figure 47 and Table 22. Figure 47: Connecting the PWM Output with Opto-isolation Table 22: Connecting the PWM Output with Opto-isolation FX14 Terminals Description 71 - AO1 V Ref Voltage Reference Signal (15 VDC 10mA max.) 72 - AO1 Analog Output PWM 60 FX14 Field Controller Technical Bulletin

61 Connecting a Fan Speed Controller without Opto-Isolated PWM Input If the PWM input of fan speed controller is not opto-isolated, then the connected load has an internal power supply for the input. See Figure 48 and Table 23. Figure 48: Connecting the PWM Output without Opto-Isolation Table 23: Connecting the PWM Output without Opto-Isolation FX14 Terminals Description 72 - AO1 Analog Output PWM 73 - AO1 Com Common Terminal IMPORTANT: When the power supply to the fan speed controller uses the same common terminal or connection on the device as the analog output, make sure to respect the same power supply connection polarity at any other device connected to the FX14 controller. Connecting AO Com to 24 V Com leads to the loss of the isolation of the microprocessor in the FX14. Not respecting the power supply polarity may result in a short circuit in the power supply. FX14 Field Controller Technical Bulletin 61

62 Digital Outputs The FX14 features nine digital (binary) outputs, available in one of the following two hardware configurations: nine relays five relays and four triacs The digital output objects in the application software provide the interface between the hardware digital output channels and the control application. You can override a digital output and modify its value via a supervisory system if the control application is configured for this feature. You can also configure digital output objects using the FX Tools software package to provide the following output types: On/Off Output This output type commands the DO (triac or relay) to switch on or off depending on the input request. Hermetic Compressor Output This output type features all the functions required to switch a hermetic compressor. This output type provides the logic, interlocking, and timing features required for such applications. Duration Adjusting Type (DAT) Output This output type commands the DO (typically a triac) to switch on or off with a time based duty-cycle proportional to the numeric input request. You can set a minimum On/Off time to avoid very short On pulses with the low range value (Output at 0%) and very short Off pulses when the value falls close to the high range value (Output at 100%). Position Adjusting Type (PAT) (Incremental Control) Output This output type commands a pair of DOs (typically triacs) to drive a synchronous reversible electric actuator in one of the two directions in response to a change in the numeric input request. A PAT output gives modulating control by using the configured actuator full-stroke (fully open to fully close) time to drive the actuator for a part of that time base in proportion to the change in the controlling numeric input. For example, for a 100-second actuator to achieve 40% open, the actuator runs 40 seconds from the fully closed position. You can set a dead band, in percent of full-stroke time, to avoid driving the actuator for very small changes in the output signal. This reduces unnecessary wear on the drive mechanism. 62 FX14 Field Controller Technical Bulletin

63 The PAT Object requires two digital output channels, typically triacs. One triac is switched on when the output must increase; the other triac is switched on when the output must decrease. The polarity of the PAT is configurable to change the increasing and decreasing physical channels without the need to rewire. At the 0 or 100% position, the duration of switching increases by a configurable value (ResyncAmount) to ensure that the valve or other controlled device is completely at its end position. When the estimated position remains fixed to 0 or 100% for a time equal to a configurable period (typically 2 hours), a synchronization action occurs according to the ResyncAmount configurable parameter. When the output remains in a fixed position for more than a configurable period, the PAT output applies the anti-sticking function, if enabled, to exercise the device and the drive mechanism. This is particularly useful for water valves that require regular activity of the inner parts to keep them free to move. Connecting the Relays! WARNING: Risk of Electric Shock and Property Damage. Disconnect or isolate all power supplies before making electrical connections. More than one disconnect or isolation may be required to completely de-energize equipment. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death. AVERTISSEMENT: Risque de décharge électrique. Débrancher ou isoler toute alimentation avant de réaliser un branchement électrique. Plusieurs isolations et débranchements sont peut-être nécessaires pour -couper entièrement l'alimentation de l'équipement. Tout contact avec des composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles. The FX14 features up to nine Digital Outputs with electromechanical relays. See Figure 49 for details of ratings. Each relay contact has a separate common terminal, ensuring a double isolation between the contact and microprocessor and between relay contacts. Having a separate common terminal and double isolation allows the connection to different voltage supplies. Figure 49: Relay Output Connection Diagram FX14 Field Controller Technical Bulletin 63

64 Figure 50 shows a typical application of the relay outputs for driving a compressor. Figure 50: Connecting a Compressor to the FX14 DO Connecting the Triacs The FX14 triac (0.5 A, 24 VAC) digital outputs normally operate in PAT and DAT modes. See Figure 51. Figure 51: Triac Output Connection Diagram For example, you can configure the triac digital outputs for PAT mode to drive incremental valve actuators such as the Johnson Controls VA-7450 actuator.

65 Operation Operation Concepts Communication Services Using a GSM modem, the FX14 Field Controller can send SMS text messages to mobile telephones to report alarms and events. Event Management The FX14 manages and records events or errors that are generated by the operating system and events or alarms that are associated with data points or variables in the control application. You can view the active events and the event history log on the user interfaces. You can also configure the event to send a message to a mobile phone via an SMS text message. Trend Logging This feature enables the recording of four variables at intervals from 1 minute to 1 day for display on the remote user interface. Time Scheduling This feature allows on/off control actions based on a weekly time schedule with holiday exceptions. After a power failure, a rechargeable capacitive battery backs up the real-time clock for a minimum of 10 days at room temperature. User Interfaces The FX14 Field Controller has several user interface options (integral or remote) to display and edit data points and configuration parameters of the running application. You can format the user interfaces to display up to five different, user-selectable languages. FX14 Field Controller Technical Bulletin 65

66 Supervisory Options You can integrate the FX14 into a supervisory building automation system for continuous monitoring of the control system. The three methods of integration include the following: N2 Open LONWORKS TP/FT-10 BACnet protocol Application Configuration and Commissioning The FX14 design is based on an object and services oriented architecture that includes configurable input/output, control algorithm and real-time functions, and serial communication options. You can create and download control applications into the FX14 controller using the FX Tools software package. The FX Tools software package includes: FX Builder: You use FX Builder to program and configure Facility Explorer controllers (using menus, navigation trees, and graphic screens). With FX Builder, you use the application configuration to define the physical inputs and outputs, data point values to be monitored, and the user interface displays of the controller. FX Builder also includes an Application Wizard that selects and configures a predefined application from a library of standard applications for Facility Explorer controllers (using selection menus and graphic screens). FX CommPro N2/LON/BACnet: Use FX CommPro N2/LON/BACnet to commission Facility Explorer controllers with parameter configuration for control sequence and loop tuning. The tools in this package also allow you to save parameter to download to other controllers with the same application. Three versions of the FX CommPro tool support controllers on N2 Open, LONWORKS, and BACnet protocol networks. 66 FX14 Field Controller Technical Bulletin

67 Security The FX Tools software package and the Facility Explorer controllers come with an embedded security features based on the use of two Identifiers (IDs): Family ID (embedded in the controller hardware at the factory) Customer ID (embedded in the application file by the user) The Family ID and the Customer ID provide protection against downloading an application to the wrong controller. The Customer ID also prevents the unauthorized access within the software tools to applications developed by other users. Application Upload/Download You can download applications to the controller with: FX CommPro N2/LON/BACnet FX Programming Key (N2 only) FX Loader utility (firmware only) FX14 Field Controller Technical Bulletin 67

68 Detailed Operation Procedures Communication Services With a GSM modem connected, the FX14 Field Controller can send SMS text messages to report alarms and events. To configure communication (notification) services, select the Application > Notification Services > SMS menu of FX Builder (Figure 53). Figure 53: Edit Service: SMS Configuration Window Refer to the FX Tools Software Package - FX Builder User Guide (LIT ) for more information about how to configure these services. Event Management The FX14 manages and records events or errors that are generated by the operating system and events or alarms that are associated with data points or variables in the control application. System events indicate that the control system requires some attention and include the following events: system powerup event log buffer full trend log buffer full communication message failure (SMS) application or display diagnostic error 68 FX14 Field Controller Technical Bulletin

69 Application events or alarms indicate that the controlled equipment requires attention or that the controlled conditions are not within the expected limits. These include the following: analog value is outside of a desired range status value represents a condition that has changed or is not in the normal condition You can define up to of 20 binary or enumerated logic values for application event monitoring with or without the requirement for acknowledgement. If an event goes into the active state, a message window appears on the display screen. You can also configure the event to send a message to a mobile phone by SMS. The event appears in the active event list and is only removed from the list when the event is no longer active and acknowledged (if required) through the user interface or by an SMS message from the mobile phone. The event is also entered into the event log with the time and date of occurrence. The event log contains up to 100 events. You can view the events on the user interface. Events Plug-in FX Builder includes an Events window (plug-in) that allows you to define and configure the system and application events and the messaging services to use. You can define a maximum of 20 events (Figure 54). The Events Icon opens the Events plug-in. Figure 54: Event Maker Plug-in FX14 Field Controller Technical Bulletin 69

70 You can associate events with changes in binary or enumerated logic variables in the Network Profile or the Application Profile. System events are predefined conditions related to the execution of the application by the operating system. The Events window allows you to select the mobile phone (SMS) destination for each event from the available Contacts or Groups defined in the Address Book. If you want to send notification to more than one contact, then you need to define a group from the address book containing all the contacts to notify. Trend Logging You can configure the FX14 Field Controller to record data samples at a defined interval from up to four variables within the control application. You can set the sample interval from every minute to once per day. For example, the onboard memory can hold a trend log of samples taken at 15 minute intervals on four variables for up to 30 days. You can view the trend data for each variable on the remote user interface (MUI). See Figure 55. You can also read the trend data using the FX CommPro N2 tool. A system event message appears if the trend buffer is not configured in the circular recording mode and the buffer becomes full. 20/03/ : C 20/03/ : C Figure 55: Trend Display on MUI Trends Plug-in The Trends window (plug-in) of FX Builder defines the variables logged in the controller memory. When you click Trends, the Trends window appears (Figure 56). Figure 56: Trends Configuration Window 70 FX14 Field Controller Technical Bulletin

71 With the Trends Maker software feature, you can define trend logging for up to four analog or logic variables from the application profile inputs and outputs. Trend Logging Memory Allocation Table 24 shows the memory allocation for the trended values. Table 24: Trend Logging Memory Allocation Memory Allocated to Trends Memory Usage for One Sample with Time Stamp 64 KB Float value = 4 Bytes Profile value = 2 Bytes Time stamp = 5 Bytes (for all samples at one time) Maximum Number of Samples (with Four Variables) 3,000 (30 days at 15-minute sample intervals) Float values are the object outputs and the profile values are the Network Profile and Application Profile variables. If one or more of the four variables are not used, the memory allocation can be used to increase the allocation of other variables. FX14 Field Controller Technical Bulletin 71

72 Time Scheduling The FX14 has a clock that supports all real-time functions. This includes the display of time and date on the user interface and the time stamping of each recorded event. After a power failure, a rechargeable capacitive battery (fully charged) can back up the real-time clock for a minimum of 10 days at 25 C (77 F). The real-time clock also enables the time scheduling of start and stop commands and occupancy mode changes to the plant you want to monitor and control. You can display and edit time schedules on the integral user interface (On/Off Scheduler only) or on a remote MUI user interface. On-Off Time Scheduler The On-Off Time Scheduler object controls a binary (On-Off) output according to a configurable event schedule, real time, day of the week, and holidays (or exception days) in the calendar. Use FX Builder to configure the scheduler. Use FX CommPro to modify the scheduler in a graphic format. You can modify the scheduler from the integral/remote interface if configured in the application. You can also define a logic command to force the Time Scheduler object output to On or Off for a simple override function from a user interface. Figure 57: On-Off Scheduler Definition Weekly Occupancy Scheduler The Weekly Occupancy Scheduler object controls a multi-state output with the states of Occupied, Standby, and Unoccupied. This is according to a configurable event schedule, real time, day of the week, and holidays (exception days) in the calendar. 72 FX14 Field Controller Technical Bulletin

73 Use FX Builder to configure the scheduler and FX CommPro to modify the scheduler in a graphic format. You can modify the scheduler from the remote interface (MUI) if the scheduler was configured in the application. You can also define a multi-state command to force the Time Scheduler object output to Occupied, Standby, or Unoccupied. This can be used as a simple override function from a user interface. Figure 58: Weekly Occupancy Scheduler Definition Exceptions Calendar Use the Exceptions Calendar in FX Builder to define holidays or exception days in a graphic format. Use FX CommPro to modify the holidays or the integral or remote user interface if configured in the application. FX14 Field Controller Technical Bulletin 73

74 User Interfaces The FX14 supports one or two user interfaces, which allows you to display and edit data points and configuration parameters of the running application. The user interface is fully configurable. The design and use of a user interface is optional and the controller can operate without the display. The FX14 may have an integral user interface (Figure 60) and can also support one remote user interface (MUI): Panel mount MUI: up to 3 m (9.8 ft) from the controller with power supply and data communication via the flat telephone cable with order code LP-KIT C Wall mount MUI: up to 300 m (984 ft) from the controller. The wall mount display must be independently powered and the data communication is transmitted over a three core shielded cable (not provided) connected to the Remote Display terminals of the FX14. You can also panel mount the wall mount version may when the panel is further than 3 m (9.8 ft) from the controller. Integral User Interface The integral user interface is fully configurable within the application. See Figure 59 and Figure 60.

86 Multi-language Database All the text on the screen is fully programmable and can be entered in up to five different languages using the table provided in the programming tool that lists all the texts for translation. You can then select the preferred language from a screen menu when you log onto the system. The user interface display configuration window (plug-in) allows you to develop the display application in the chosen primary language. The export feature then transfers of all the different text strings and names of variables to a file for translation. The first language determines the length of each text and the other language translations cannot exceed this text length. The import feature inserts the additional language databases into the display application and makes it ready to download. This feature is designed for equipment manufacturers who export systems to many countries or for systems in areas where more than one language is spoken. 86 FX14 Field Controller Technical Bulletin

87 Supervisory Option You can integrate the FX14 Field Controller into a supervisory building management system for continuous monitoring of the control system. The FX14 supports three methods of integration: N2 Open network LONWORKS TP/FT-10 network BACnet MS/TP network. N2 Open Network You can connect an FX14 with an N2 Open communication card to the N2 Open network of a supervisory system such as a Building Automation System (BAS). The BAS then has access to the control network variables and parameters available in the network profile of the FX14. The list of variables and parameters available to the network is defined in the N2 network profile. The N2 network profile is part of the application loaded to the controller. You can customize the network profile for each device. The FX14, like every other controller in the Facility Explorer family, is an N2 Open Compatible Vendor Device (VND). FX Builder generates a file (.prn) that contains the relevant information from the control application for the integration of the FX14 controller into a supervisory system or controller with an N2 Open interface. The.prn file contains columns labeled Point Type and Point Address. This information generates the Network Point Type and Network Point Address in the supervisory system or controller. N2 Open Network Profile Limits The FX14 N2 Open interface exposes up to 62 volatile application points and up to 100 permanent application points to the N2 Open network profile. The device application profile imposes this limitation. Each application point may be mapped into one of the seven regions (data types) of the N2 Open protocol using FX Builder. FX14 Field Controller Technical Bulletin 87

88 LONWORKS Network You can order the FX14 controller with a LON communication card. The LON communication card enables the FX14 controller to send data to other LON controllers on a LONWORKS network. The FX14 controller can also send data to a supervisory system or controller fitted with a LONWORKS network interface card. Use FX Builder to define both the control application and the LON network profile for the FX14. The Network Variable Input (NVI) and Network Variable Output (NVO) points in the network profile of the control application can be configured by a LONWORKS network configuration tool to transmit and receive data over the LONWORKS bus. This allows a network of FX14 controllers fitted with the LON communication card to share data on a peer-to-peer basis. A network supervisory controller is not required unless you want a LON supervisory system to monitor the network. FX14 Field Controller LONWORKS Limits The FX14 LONWORKS interface can expose to the network up to 62 Networks Variables (NVIs, NVOs) and 100 Configuration Parameters (CPs) from the application points in the Application Profile of the FX14 to the LONWORKS Network Profile. This limitation is imposed by the LONWORKS Neuron processor on the communication card. 88 FX14 Field Controller Technical Bulletin

89 BACnet MSTP Network You can connect an FX14 with a BACnet communication card to the BACnet MS/TP bus network of a supervisory system such as a Building Automation System (BAS). The BAS then has access to the control network variables and parameters available in the FX14 s network profile. The list of variables and parameters available to the BACnet network is defined in the BACnet network profile. The BACnet network profile is part of the application loaded to the controller and can be customized for each device. BACnet Network Profile Limits The FX14 BACnet network interface exposes up to 62 network volatile application points and up to 100 permanent application points as Application Points to the BACnet Network Profile. The device application network profile imposes this limitation. Each application point, depending on its data type, can be mapped to one of the supported BACnet object types of the BACnet protocol using FX Builder. See Table 43 to view the maximum number of BACnet objects of each type that you can define in the BACnet Network Profile within the FX14 Master Controller. Table 43: BACnet Supervisory Network Profile Maximum Limits BACnet Object Qty BACnet Object Qty Description Description Analog Input 6 Calendar 2 Analog Output 4 Device 1 Analog Value 60 Event Enrollment 16 Binary Input 12 Multistate Value 77 Binary Output 9 Notification Class 2 Binary Value 10 Schedule 4 FX14 Field Controller Technical Bulletin 89

90 Application Configuration and Commissioning FX Builder You can program and configure the FX14 controller using the menus, navigation trees and graphic screens of FX Builder. FX Builder is part of the FX Tools Pro software package. The configuration includes the definition of the devices to connect, the physical inputs, outputs, and data points to monitor; and the format of the user interfaces. You can generate applications in a graphic screen environment with features that help you build the application quickly and accurately. The applications are built from standard function modules and control objects that nest in custom assemblies and can be saved for reuse in other applications. FX Builder offers complete flexibility in the generation of custom applications but has the features to reuse existing assemblies and standard applications where appropriate for an economic solution. The configuration includes the definition of the physical inputs and outputs, the data point values to be monitored for supervisory, commissioning and servicing functions, and the format of the user interface displays. You can define the communication parameters for supervisory functions and event messaging in FX Builder. You can define user profiles with passwords to protect the FX14 controller from unauthorized access. You also generate and configure trend logs and time schedules in FX Builder. FX Builder builds the control functions that the FX14 controller executes, including the commands from the integral or remote display, SMS messages, or a supervisory system if connected to the controller via a communications card. The FX14 controller arrives without an application and the application is normally downloaded in the Original Equipment Manufacturer (OEM) factory or at the job site. If you want to load a standard application into a large number of controllers, the controller can be delivered from the factory with the application already loaded on request. 90 FX14 Field Controller Technical Bulletin

91 Figure 76: Screen from the FX Builder Tool Control Application and Network Profile Use FX Builder to build the control application that the FX14 controller executes when downloaded into the controller. You also use FX Builder to generate a network profile through which the controller communicates to other devices on a control system network. You can select the network profile for the N2 Open protocol, the LON protocol, or the BACnet MS/TP protocol. Use FX Builder to build the control algorithm and logic on a graphical canvas by creating and connecting instances of the objects in the database of the controller. An object is a functional block with inputs, attributes, an internal processing method, and outputs. By means of connections between inputs and outputs, values can pass between the objects or between the objects and the network profile. A connection has always the same direction: from the source to the destination. Sources can be the network variables inputs and configuration parameters in the network profile, and the object outputs. Destinations are the network variable outputs in the network profile and the object inputs. The object uses the object inputs to read values coming from other objects or from the control system network via the network profile. The object uses the object outputs to present its results. The object outputs can then be used by other objects or they can be sent to other devices through the network profile and the control system network. FX14 Field Controller Technical Bulletin 91

92 The objects also have some static values (which can be set only at design-time), known as attributes, which are typically used to determine the behavior of an object or used as default values in case the input values are missing or have invalid values. When you develop an application, you can use a maximum of 200 instances of the available objects. The available objects in the FX14 controller appear in Table 44. The control application and logic can also interact with the alarm and event management, user interfaces, and communication services to generate information and alarm messages for the user. Distributed Application In addition, use FX Builder to build a distributed application that encompasses the control functions of a master controller. The FX16 Master Controller supports 16 slave controllers and the MD20 Master Display supports 8 slave controllers on its local link bus. Any or all of the slave controllers can be an FX14 controller. The application is downloaded to the master controller, which then automatically downloads the appropriate part of the application to the slave controllers. 92 FX14 Field Controller Technical Bulletin

Note: The previous versions of the enhanced objects appear in FX Builder for the FX14 controller as Obsolete and are available only for older applications. You can use several objects of the same type within one control application. Each copy of an object type is called an instance of the object, and you can configure each instance differently according to the application requirements. For example, to read the physical inputs AI1 and AI2 on a controller, the control application should include two instances of the Analog Input object, which differ in their configuration. One instance is configured to read Channel 1. The other instance should read Channel 2. The FX14 controller supports up to 200 object instances in the control application. FX14 Field Controller Technical Bulletin 95

96 FX CommPro N2/LON/BACnet Use FX CommPro (available in the N2 Open, LON, and BACnet versions) to commission Facility Explorer devices including the FX14 controller. In FX CommPro, you can display and monitor the network profile of the connected controller with its Inputs, Outputs, Values, and Configuration Parameters. See Figure 77. Depending on the protocol used and the selection of objects and data types, some variables and parameters are read/write values and you can modify them. However, other variables and parameters are for monitoring purpose only and you cannot modify them. Use FX CommPro to download the control application into the FX14 controller. FX CommPro N2 monitors and downloads applications (using the N2 Open protocol) when the FX14 is equipped with an N2 Open or RS-232C communication card. FX CommPro LON monitors and downloads applications using the LON protocol when the FX14 is equipped with a LON communication card. FX CommPro BACnet monitors and downloads applications using the BACnet MS/TP protocol when the FX14 controller is equipped with BACnet communication card. Figure 77: FX CommPro Tool Main Screen On the FX CommPro, you can display and monitor the network profile of the connected controller with its inputs (NVIs), configuration parameters (CPs), and outputs (NVOs). 96 FX14 Field Controller Technical Bulletin

97 NVIs and CPs are read/write values; therefore, you can modify them. NVOs variables cannot be modified and are for monitoring only. Use FX CommPro to download the control application into the FX14 controller. FX CommPro N2 monitors and downloads using the N2 Open protocol when the FX14 is equipped with an N2 Open or RS-232C communication card. FX CommPro LON monitors and downloads applications using the LON protocol when: the FX14 is equipped with a LON communication card the computer running FX CommPro LON has a LONWORKS interface card and driver or an external LON converter module FX Loader Utility Use FX Loader (Figure 78) to download an FX14 control application into the FX Programming Key (N2 protocol only). FX Loader can also download an application using the N2 Open or LON protocol according to whether the FX14 is equipped with an N2 Open, RS-232C, or LON communication card. From FX Loader, you can also download firmware updates to the FX14 controller and other devices in the FX platform (via N2 Open communication card only).

100 Customer ID The customer ID protects a custom developed application within a controller. The customer ID also prevents unauthorized users from editing the application source code in FX Builder. Three Customer ID types are used: Public ID (default) Any user with the Public ID enabled in FX Builder can modify, download, and commission applications configured and saved with the Public ID. All controllers (except demo controllers) arrive from the factory with the Public ID as default. Demo ID You can only download applications configured and saved with the Demo ID to demo controllers (with the Demo ID in their database) or to controllers with the Public ID. Only users with the Demo ID in FX Builder can modify applications with the Demo ID. The FX Tools CD provides the Demo ID and is normally used in sales offices. Use the Demo ID to prevent demonstration equipment or product samples from being used for installations. Customer Specific/Private ID Only users with the same Customer Specific ID enabled in FX Builder can read and modify source files for applications configured and saved with a Customer Specific ID. Once you download a controller with a Customer Specific ID, the controller becomes customer specific and only allows users with the same Customer Specify ID to download applications. Unique Customer IDs are available to branch offices on request. Special Customer ID files are not included on the FX Tools CD. You can only reset a controller with a Customer Specific ID to the Public ID by returning it to the Johnson Controls factory or repair center. 100 FX14 Field Controller Technical Bulletin

101 Application Download With the FX14, you can download the control application to the controller via a computer with software in the FX Tools Suite. You can also download applications via the FX Programming Key (N2 applications only). Computer Connection To download an application via a connection to a computer, the FX14 needs to have a communication card (N2 Open, RS-232C, LON, or BACnet) installed. N2 Open or RS-232C Card Use an RS-232C to RS-485 converter (for example, IU-9100 or LP-KIT C) to connect the computer to the Supervisory Link terminals of the N2 Open card of the FX14. Make sure the converter supports the Automatic Send Data Control and does not require Request To Send (RTS)/Clear to Send (CTS) control. Use a null-modem cable (see Ordering Codes) to connect the computer to the Supervisory Link terminals of the RS-232C card of the FX14. Use FX CommPro N2 to download the application. Select N2 Open or Direct for RS-232C. The N2 Open network profile or communication service parameters are also downloaded to the FX14 controller. LON Card Use an SLTA or a PCC10 LON interface converter to connect the computer to the Supervisory Link terminals of the LON card of the FX14 controller. Use the FX CommPro LON to download the application. The LON network profile is also loaded into the LON card. BACnet Card Use a BACnet IP to MS/TP Adapter (for example, Ordering Code LP-KIT C) to connect the computer to the Supervisory Link terminals of the BACnet card of the FX14 controller. Note that the adapter must support the MS/TP protocol; a simple Ethernet IP to RS-485 converter is not able to communicate on the BACnet MS/TP bus. Use the FX CommPro BACnet to download the application. The BACnet network profile is also downloaded to the FX14 controller. FX14 Field Controller Technical Bulletin 101

102 FX Programming Key (N2 Applications Only) The FX Programming Key allows you to download an application to the FX14 controller. This situation is convenient if you load multiple controllers with the same application on a construction site or in the factory at the end of the production line. To load the FX14, you just press a button. There is no need for a computer, communication card, or converter. Before you use the Programming Key, you need to load it with the desired application. You can load the Programming Key via FX Loader (Version and later) or you can load it from a preprogrammed FX14 controller. Loading the Programming Key from a Preprogrammed FX14 To load the Programming Key from a Preprogrammed FX14: 1. Remove power from the FX14 Controller. 2. Connect the Programming Key to the remote display terminals of the FX14 controller. Note: The FX Programming Key also connects to the communication port in the integral display panel of the FX14 (if installed). To access the programming key port, slide the keypad to the right, away from the display. You may need to use a small screw driver to release the keypad section from the display section. 3. Restore power to the FX14 Controller. The two LEDs on the Programming Key blink alternately. This indicates that you have to select an operation. 4. Press the Programming Key button to move from uploading to downloading and vice-versa (the corresponding LED blinks quickly). 5. Make sure the green Upload LED is blinking and then confirm the Uploading action by pressing the button for more than 3 seconds. During the upload process, the LED blinks. When the operation successfully ends, the blinking stops and the green LED remains on. If the operation fails, the two LEDs blink together. Note: If a user changes the parameter values in the source FX14 controller via the display or computer connection using FX CommPro, these changes do not upload to the Programming Key. The uploaded application contains the parameter defaults previously saved by FX Builder at design time. Once loaded, you can use the Programming Key to download the application to other FX14 controllers. 102 FX14 Field Controller Technical Bulletin

103 Loading the Programming Key from FX Loader To load the Programming Key from FX Loader: 1. Connect the Programming Key to an RS-485/232 converter via the plug-adapter. 2. Provide power to the Programming Key with an AC/12VDC power adapter. Figure 79: Loader - Device Selection Page 3. Start FX Loader. 4. Select N2 Open and the FX-AppKey icon (Figure 79). 5. Power the Programming Key via the AC/DC adapter. The two LEDs start blinking alternately, indicating that you need to select an operation. 6. Select the application in FX Loader to load (Figure 80). FX14 Field Controller Technical Bulletin 103

104 Figure 80: Application Selection 7. Press the Programming Key button until the green Upload LED blinks. 8. Press the button for 3 seconds to confirm the Upload action. 9. Click Next. 10. Click Download (Figure 80) to transfer the application from FX Loader to the Programming Key. If the key already contains an application, FX Loader asks you whether you want to keep or erase it. If you answer No, the operation ends. If you answer Yes, the application in the Programming Key erases and the new application loads. When the application loads, the LED blinks. When the operation ends successfully, the blinking stops and the green LED remains on. If the operation fails, the two LEDs blink together. 104 FX14 Field Controller Technical Bulletin
