9 CHAPTER 1 Introduction This manual describes the ControlNet Network Communication Option board. (M/N 915FK2101). This kit allows a FlexPak 3000 or a WebPak 3000 DC drive to send and receive data via a control processor over the ControlNet network. WebPak 3000 drives (version 1.1 or later) require version 2.2 or later of the ControlNet Network Option board. FlexPak 3000 drives (version 4.2 or later) are compatible with all versions of the network option board. Unless specified otherwise, the material in this manual applies to both FlexPak 3000 and WebPak 3000 drives. 1.1 Network Option Board Description The ControlNet Network Communication Option board makes the drive a slave node on the ControlNet network. It is a printed circuit board assembly that mounts inside the drive and connects to the drive s Regulator board through a ribbon cable. The network option board is powered from the standard drive power supply. The network option board has an RJ-45 connector that is used as a Network Access Port (NAP) that allows temporary access to the network and/or products connected to the network. A 9-pin D-shell connector is used for RS-232 communication to program the flash memory on the board. Two BNC connectors are used for ControlNet communication. A drop cable is used to link each BNC connector through a passive tap to the network. The network option board contains its own microprocessor. The microprocessor connects to one port of the board s dual-port memory. The other port interfaces with the drive s Regulator board. The ControlNet Network Communication Option board is shown in figure 1.1. Introduction 1-1

Tap Trunk Cable Terminator Figure 2.5 Connecting a FlexPak 3000 Drive or a WebPak 3000 Drive to the ControlNet Network You can run a second trunk cable between your ControlNet nodes for redundant media. With redundant media, nodes send signals on two separate segments. The receiving node automatically compares the quality of the two signals and accepts the better signal. This also provides a backup cable should one cable fail. When using redundant media, you must use two passive taps. If you do not use redundant media, the option board can operate using only channel A or channel B, as long as all other drops on the network are also on the same channel. 2.3 Connecting a Programming Device to the Option Board s Network Access Port You can gain full access to the ControlNet network by connecting a programming device to the option board s Network Access Port, an RJ-45 connector. Important: Be sure to use a network access cable that is approved by a ControlNet vendor. Using an unsuitable cable could result in network failures. 2-4 ControlNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives

17 CHAPTER 3 Drive Configuration This chapter describes how to configure a drive for use with a ControlNet network. The sections that follow describe all of the FlexPak 3000 and WebPak 3000 drive parameters related to ControlNet operation. 3.1 Setting NETW DROP NUMBER (P.900) Use NETW DROP NUMBER (P.900) to assign a node number to the drive. The node number can be changed (through a local operator interface) only when the drive is stopped. This parameter cannot be written over the ControlNet network. The node number must be changed to a value greater than 1 to begin ControlNet communication. After the network has been configured and after NETW DROP NUMBER is set to a value greater than 1, NETW COMM STATUS (P.908) should indicate ACTIVE. If the node number is changed from any value other than 1, the new value must be saved to non-volatile memory and then the power to the drive must be turned off and back on to have the new value take effect. If NETW DROP NUMBER is not equal to 1 on power up, the drive will attempt to communicate on the ControlNet network immediately after the drive diagnostics are complete. Range: 1-99 Type: Non-volatile, Configuration (Read-only over the ControlNet network) Default: 1 (Drive is not communicating on the network) 3.2 Setting CONTROL SOURCE SELECT (P.000) CONTROL SOURCE SELECT (P.000) determines the source of control information for the drive (start, jog, direction, etc.). Setting CONTROL SOURCE SELECT to NETWORK allows the drive to be controlled, and the reference to be supplied, from the ControlNet network. After CONTROL SOURCE SELECT is set to NETWORK, the LCD status on the OIM keypad should change to show the network is in control of the drive. Note that setting CONTROL SOURCE SELECT to any value but NETWORK does not prevent the drive from communicating on the ControlNet network. In other words, CONTROL SOURCE SELECT does not have to be set to NETWORK to modify or read drive parameters. Range: TERMBLK (1), KEYPAD (2), SERIAL (3), NETWORK (4) Type: Non-volatile, Configuration Default: TERMBLK (1) Drive Configuration 3-1

18 3.3 Setting CNI PROG/RUN MODE (P.915)! ATTENTION: CNI PROG/RUN MODE (P.915) allows you to configure the drive to continue to run when the PLC is put into program mode. You must provide some form of hardwired stop in case of communication loss, since stopping the drive through the network might not be possible. Failure to observe this precaution could result in bodily injury or damage to, or destruction of, equipment. CNI PROG/RUN MODE (P.915) selects how the drive will respond when communicating with a PLC that is put into program mode while CONTROL SOURCE SELECT (P.000) is set to NETWORK. When the PLC is put into program mode, alarm A00006 (CNI PROGRAM MODE), is generated to indicate the change in operation of the drive. An alarm is not generated when the PLC is returned to run mode, since that is considered normal operation. When CNI PROG/RUN MODE = STOP (1), the drive will coast/db stop when the PLC is put into program mode. The drive can be started only when the PLC is in run mode. When CNI PROG/RUN MODE = USE LAST REF (2), the drive will not stop (if running) or start (if stopped) when the PLC is put into program mode. The drive will continue to use the last network reference received as its speed reference. This will continue until the PLC is returned to run mode and a new reference value is received. When CNI PROG/RUN MODE = USE TRMBLK CNTL (3), the drive will not stop (if running) or start (if stopped) when the PLC is put into program mode (or returned to run mode). The drive's terminal block will become the source for all control (run, jog, stop, fault reset, direction and OCL enable) and speed (auto) reference signals. For FlexPak 3000 drives, the Speed Loop PI Reset and Underwind/Overwind bits cannot be changed while operating in this mode. They will remain at the last values received from the network. This will continue until the PLC is returned to run mode when control/reference will come from the network again. Range: STOP (1), USE LAST REF (2), USE TRMBLK CNTL (3) Type: Non-volatile, Configuration Default: STOP (1) 3.4 Setting NETW COMM LOSS SELECT (P.901) (FlexPak 3000 Drives Only)! ATTENTION: NETW COMM LOSS SELECT (P.901) allows you to configure the drive to continue to run if a loss of network communication occurs. You must provide some form of hardwired stop in case of communication loss, since stopping the drive through the network might not be possible. Failure to observe this precaution could result in bodily injury or damage to, or destruction of, equipment. NETW COMM LOSS SELECT (P.901) is not used in WebPak 3000 drives. For WebPak 3000 drives, a fault is generated when network communication is lost if CONTROL SOURCE SELECT (P.000) is set to NETWORK. This causes the drive to coast/db stop. The drive cannot be restarted until the fault is cleared. 3-2 ControNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives

19 For FlexPak 3000 drives, NETW COMM LOSS SELECT (P.901) defines how the drive will respond to network communication loss when CONTROL SOURCE SELECT (P.000) is set to NETWORK. Alarms do not cause the drive to stop. Therefore, some form of hardwired stop must be available in case of communication loss, since stopping the drive through the network might not be possible. When NETW COMM LOSS SELECT = FAULT (1), a fault is generated when network communication is lost, causing the drive to coast/db stop. The drive can not be restarted until the fault is cleared. When NETW COMM LOSS SELECT = HOLD LAST REF (2), the drive continues to run if network communication is lost, using the last reference value received over the network. Alarm A00004 (NETWORK COMMUNICATION TIMEOUT) is generated if network communication is lost. The drive will maintain the last reference until network communication is reestablished and a new drive reference value is provided. When NETW COMM LOSS SELECT = USE TRMBLK REF (3), the drive continues to run if network communication is lost, using the selected auto reference value from the regulator board terminal strip (terminals 19 and 20). The drive automatically switches back to the network reference when network communication is re-established. Alarm A00004 (NETWORK COMMUNICATION TIMEOUT) is generated if network communication is lost. The drive can still be stopped through the terminal block and local keypad, but can not be restarted. When NETW COMM LOSS SELECT = USE TRMBLK CNTL (4), the drive continues to run if network communication is lost. The Regulator board terminal strip will become the source for all control (run, jog, stop, fault reset, direction and OCL enable) and speed (auto) reference signals. The Speed Loop PI Reset and Underwind/Overwind bits can not be changed while operating in this mode. They will remain at the last values received from the network. The drive automatically switches back to the network reference and control when network communication is re-established. Alarm A00004 (NETWORK COMMUNICATION TIMEOUT) Is generated if network communication is lost. Range: FAULT (1), HOLD LAST REF (2), USE TRMBLK REF (3), USE TRMBLK CNTL (4) Type: Non-volatile, Tunable Default: FAULT (1) 3.5 Setting NETW OUT REG 1 SELECT (P.902) NETW OUT REG 1 SELECT (P.902) defines a parameter number whose value will be monitored and saved in the network option board s dual-port memory. For example, setting this parameter equal to 588 will cause the value of FIELD DELTA (P.588) to be written to file address N10:47 in the dual-port memory for FlexPak 3000 drives, address N10:87 for WebPak 3000 drives. Range: to Type: Non-volatile, Tunable Default: 0 Drive Configuration 3-3

20 3.6 Setting NETW OUT REG 2 SELECT (P.903) NETW OUT REG 2 SELECT (P.903) defines a parameter number whose value will be monitored and saved in the network option board s dual-port memory. For example, setting this parameter equal to 588 will cause the value of FIELD DELTA (P.588) to be written to file address N10:48 in the dual-port memory for FlexPak 3000 drives, address N10:88 for WebPak 3000 drives. Range: to Type: Non-volatile, Tunable Default: Setting NETW OUT REG 3 SELECT (P.904) NETW OUT REG 3 SELECT (P.904) defines a parameter number whose value will be monitored and saved in the network option board s dual-port memory. For example, setting this parameter equal to 588 will cause the value of FIELD DELTA (P.588) to be written to file address N10:49 in the dual-port memory for FlexPak 3000 drives, address N10:89 for WebPak 3000 drives. Range: to Type: Non-volatile, Tunable Default: NETW COMM STATUS (P.908) NETW COMM STATUS (P.908) indicates the status of network communication. When NETW COMM STATUS = NOT ACTIVE, the network option board is not communicating on the ControlNet network. When NETW COMM STATUS = ACTIVE, the network option board is communicating properly with the ControlNet network. Range: NOT ACTIVE (1), ACTIVE (2) Type: Read-only (output) 3.9 NETW TYPE & VERSION (P.909) NETW TYPE & VERSION indicates the type of network board installed and its software version. The format is of the form TV.VV, where: T = board type: 2 = AutoMax, Profibus, InterBus 4 = DeviceNet (FlexPak 3000 drives only) 5 = ControlNet V.VV = major and minor version numbers (e.g. 1.03) Range: to Type: Read-only (output) 3-4 ControNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives

21 3.10 NETWORK KIT (P.796) NETWORK KIT (P.796) indicates whether the network option board is operating correctly in the drive. Range: PRESENT (1), NOT PRESENT (2), FAILED DIAGS (3) Type: Read-only (output) 3.11 NETW IN REG 1 (P.905) NETW IN REG 1 (P.905) indicates the value being written by the network master into file address N11:10 in the network option board s dual-port memory.

23 CHAPTER 4 Programming the Drive This section describes how to program the drive over the ControlNet network. 4.1 About ControlNet Network Communication The ControlNet network transports time-critical control information (for example, drive reference and feedback information) as scheduled data, as well as non-time-critical information (for example, accessing drive parameters) as unscheduled data. The transportation of the non-time-critical information does not interfere with the time critical messages. A node s access to the network is controlled by a time-slice access algorithm, which determines a node s opportunity to transmit in each network update interval. You configure how often the network update interval repeats by selecting a network update time (NUT) in milliseconds. The minimum network update time you can specify is 2ms. The network update time is how often you want to send scheduled traffic. You configure when a node will transmit during the network update time (scheduled vs. unscheduled). See table 4.1 for more information about the components of the network update time. Table 4.1 Network Update Time Components Network Update Time Component scheduled unscheduled Function Information that is time-critical (drive reference and feedback) should be sent during this part of the NUT interval. Information that can be delivered without time constraints should be sent during this part of the NUT interval. The amount of time available for the unscheduled portion is determined by the traffic load of the scheduled portion. During this part of the interval, nodes may have many or no chances to transmit. For optimum throughput, assign addresses to ControlNet nodes in a sequential order. Programming the Drive 4-1

24 4.2 Configuring Drive Reference and Feedback Data as Scheduled Transfers This section describes how to: configure scheduled traffic for the drive control the drive using the drive reference data use scheduled drive feedback data Configuring Scheduled Data Transfers Before the drive can communicate on the ControlNet network, you must configure its scheduled traffic information by using some type of ControlNet configuration software. By configuring scheduled traffic, you define how much data the drive can send, how often the data is sent, and where the data is written to and read from (mapped) in the programmable controller. You must configure each drive on the ControlNet network. Table 4.2 lists the configuration information you must enter if you are using RSNetWorx and a PLC-5. Table 4.2 ControlNet Scheduled Traffic Configuration Fields In this field: Enter this information: Node Enter the drive s node number that you defined in P.900. Slot These fields are not used by the drive. Message Module Enter FlexPak 3000 or WebPak API This field is read-only. RPI Enter how often you want to exchange scheduled data between the programmable controller and the drive. Connection Type Select Exclusive Owner. FlexPak 3000 and WebPak 3000 drives do not support Multicast operation. Input Address Enter the programmable controller s integer file number that will store data received from the drive (drive feedback data). Input Size Enter the number of words of drive feedback data that you want the programmable controller to receive from the drive (1 to 8). See section for information about the type of data that is sent. Output Address Enter the programmable controller s integer file number that will store data sent to the drive (drive reference data). Output Size Enter the number of words of drive reference data that you want the programmable controller to send to the drive (1 to 8). See section for information about the type of data that is sent. Status Address Enter the programmable s integer file number that will store the status of the ControlNet connection to the drive. Config Address These fields are not used by the drive. Config Size 4-2 ControlNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives

25 4.2.2 Programming Scheduled Drive Reference Data Setting CONTROL SOURCE SELECT to NETWORK allows the scheduled data from the PLC to control the drive. If CONTROL SOURCE SELECT NETWORK, then scheduled drive reference data from the ControlNet network is not used. The scheduled drive reference data can be configured as one to eight words of data. The first word of the scheduled drive reference data is always the drive control word; it is written in element 0 of the Output file. Should you configure less than eight words of output data, you can access the Scheduled Drive Reference Data through file N12 (see section 4.3) as unscheduled data messages. You must create a drive control application program to run in the programmable controller. This application program must write from one to eight words of data to the file you defined during drive configuration as the Output Address. The value you defined as the Output Size determines how many words of data the option board can accept from the programmable controller. During a scheduled data transfer, the programmable controller writes the data contained in the Output Address to the option board. Reference and control information is scanned by the drive at different rates depending on the type of data and the drive operating mode (speed regulator or voltage regulator). If the drive is configured as a speed regulator, all of the reference inputs are evaluated every 5 ms for FlexPak 3000 drives, every 10 ms for WebPak 3000 drives. If the drive is configured as a voltage regulator, all of the reference inputs are scanned every 10 ms. The drive control bits are always evaluated every 20 ms. Table 4.4 describes the function of each word of the FlexPak 3000 scheduled drive reference data. Table 4.5 describes the function of each word of the WebPak 3000 scheduled drive reference data.

This word is written to by the ControlNet network to command a field reference value. 1= 1/4095 of MOTOR HOT FLD AMPS (P.510). This value is only used by the drive if a field current regulator kit is installed. Unused Using Scheduled Drive Feedback Data The scheduled drive feedback data provides status to the programmable controller. This data is sent over the ControlNet network as scheduled data, which is transmitted at the configured update rate. However, the FlexPak 3000 drive sends the feedback data to the option board every 5 ms and the WebPak 3000 drive sends the feedback data to the option board every 10 ms, independent of the value of CONTROL SOURCE SELECT (P.000). Scheduled drive feedback data is composed of one to eight words. You must create a drive control application program to run in the programmable controller to read from one to eight words of data to the file you defined during drive configuration as the Input Address. The value you defined as the Input Size determines how many words of data the programmable controller accepts from the option board. During a scheduled data transfer, the option board writes the data contained in the Input Address to the programmable controller. The first word of the scheduled drive feedback data is always the drive status word; it is written to element 0 in the Input file. Should you configure less than eight words of input data, you can access the drive reference and feedback data through file N12 as an unscheduled data transfer. See section 4.3. Table 4.5 describes the function of each word of the FlexPak 3000 scheduled drive feedback data. Table 4.6 describes the function of each word of the WebPak 3000 scheduled drive feedback data. 4-6 ControlNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives

The drive sends and receives Typed Read and Typed Write messages. Refer to the appropriate instruction manual to configure your system to use Typed messages. 4-8 ControlNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives

31 4.3.1 About MSG Instruction Timing When a Typed Read message is sent to the drive, the response is returned in under 20 ms. When a Typed Write message is sent to the drive, the message is first processed by the drive. Therefore, up to 600 ms may elapse before the response is returned. These times are applicable only when the network update time and unscheduled traffic bandwidth are not limiting factors About the Files You Can Access When you send an unscheduled message to the drive, the data table address you specify for the target device determines what drive information you want to access. The data table address is in the form of: Nff:eee where: N specifies the file type as integer, ff is the file number, and eee is the element number (word). The network option board supports these file numbers: N10 -- Drive parameters (read and write) N11 -- Drive display data (read only) N12 -- Drive reference and feedback data (read and write) N20 -- Status of the most recent write parameter command (read only) Figure 4.2 shows how the drive information maps to the drive information integer files. Unscheduled Traffic File in Drive Option Board N10:0 - N10:273 N11:0 - N11:172 N12:0 - N12:31 N20:0 - N20:273 Drive Information Read/Write Parameters (500 ms update) Drive Display Data (100 ms update) Reference and Feedback Data (FlexPak: 5 or 10 ms update; WebPak: 10 ms update) Write Status (Read Only) Scheduled Traffic Figure 4.1 Drive Information Map Using the Drive Parameters Data (N10:x) Beginning at N10:0, the PLC can read from and write to drive parameters. The drive processes these parameters every 500 ms. From N10:1 - N10:06, there is a one-to-one mapping with P P.006. Programming the Drive 4-9

32 All the parameters may accessed with one message block. Any contiguous subset of the parameters may be changed without sending a new copy of the entire block. Some of the parameters are marked Config (configuration), meaning that they may only be changed while the drive is stopped. Any attempt to change the value of these parameters while the drive is in a running state will result in an error, and the value in the drive will not be changed. For this reason, the configuration parameters are all grouped together after the tunable parameters. (CONTROL SOURCE SELECT (P.000) is located at the start of the Config section, N10:150.) Tunable and configuration parameters are also grouped according to potential frequency of use, from most-used to least-used. Refer to table 5.1 for a listing of the file N10 parameters for FlexPak 3000 drives. Refer to table 6.1 for a listing of the file N10 parameters for WebPak 3000 drives Using the Drive Display Data (N11:x) The drive display data can be accessed beginning at N11:0. Attempting to write to any of these parameters will cause an error. The drive updates these parameters every 100 ms. Selected speed feedback parameters are updated at the speed loop scan period (FlexPak 3000 drives: 5 ms for a speed regulator, 10 ms for a voltage regulator; WebPak 3000 drives: 10 ms for a speed regulator, 10 ms for a voltage regulator). Refer to table 5.2 for a listing of the file N11 parameters for FlexPak 3000 drives. Refer to table 6.2 for a listing of the file N11 parameters for WebPak 3000 drives Using the Drive Reference and Feedback Data (N12:x) When scheduled traffic is reduced to transmit only a subset of the drive reference and feedback data, the information that is not transmitted as scheduled data can be accessed in file N12 as unscheduled data. The drive updates this data at the speed loop scan period (FlexPak 3000 drives: 5 ms for a speed regulator, 10 ms for a voltage regulator; WebPak 3000 drives: 10 ms for a speed regulator, 10 ms for a voltage regulator). A message block can be used to read any or all of the data. The Drive Control word and all of the Drive Feedback data are read only when accessed through file N12. All other words accessible through file N12 are read/write. Refer to table 5.3 for a listing of the file N12 parameters for FlexPak 3000 drives. Refer to table 6.3 for a listing of the file N12 parameters for WebPak 3000 drives Using the Write Status (File N20:x) to Troubleshoot a Drive Parameter You can troubleshoot errors that may occur when you write values to parameters to the drive. When a write command is sent from the PLC to the drive, it is possible that the value may not be accepted because: The parameter is read-only The parameter is a configuration parameter and the drive is in run or jog The value is out of range (less than the minimum or greater than the maximum) 4-10 ControlNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives

33 When this occurs, the MSG instruction s ER coil is set and an error code (=11 or 0B hex) is written into an element in N20 that corresponds to the parameter that was not accepted. For every element in N10:x there is a corresponding element in N20:x. In response to the error coil, the PLC can read N20:x to find out which parameters were not accepted. When parameters are written to, only the corresponding status words are updated. If a valid value is written, the corresponding element in N20:x is cleared (= 0). See table 7.1 for the error codes that the drive will return to the PLC when a Typed Read or Typed Write message fails. Programming the Drive 4-11

35 CHAPTER 5 Configuring ControlLogix Applications Chapter 5 provides information and examples that explain how to use I/O Messaging to control, configure, and monitor scheduled and unscheduled data on a FlexPak 3000 or Webpak 3000 drive using a ControlNet scanner module.! ATTENTION: The examples in this publication are intended solely for purpose of example. There are many variables and requirements with any application. Rockwell Automation does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication. Failure to observe this precaution could result in bodily injury or damage to equipment. Configuring a ControlLogix CNB scanner, and the network, is mainly done using RSLogix 5000 software (figure 5.1). RSNetWorx is still required, but only at the end of the configuration process.

45 CHAPTER 6 Configuring SLC500 Applications Chapter 6 describes how to configure a SLC500 PLC on a ControlNet network with a FlexPak3000 or Webpak3000 drive. Both the 1747-SCNR and 1747-KFC15 modules are required to communicate fully with a drive and both must be configured as drops on the ControlNet network. If the application only calls for access to Drive Reference and Feedback Data (such as Drive Control and Status Words), and does not call for access to any N10, N11, or N12 drive parameters, the 1747-KFC card will not be required. However, Unscheduled Messaging will not be possible and another connection option to the processor will be required for downloading the required ladder logic. The examples in this chapter reference a FlexPak3000 drive. A similar process can be followed if your application uses a Webpak3000 drive with the appropriate ControlNet Options Board. Your rack configuration for the Webpak3000 may be different then the included examples. Adjust the examples to match your Nodes and Slots accordingly. This chapter is intended for use by personnel familiar with the installation and operation of the Reliance Drive and the installation, programming, I/O configuration and operation of the SLC processor using RSLinx, RSLogix 5000 and RSNetWorx for ControlNet software. Personnel should also be familiar with the system configuration documentation. 6.1 Required Software and Equipment Software and equipment required for configuring a SLC500 on a ControlNet network is listed in table 6.1. Table 6.1 Required Software and Equipment Equipment Description RSLinx Software RSNetWorx for ControlNet software RSLogix 500 software SLC 500 Chassis w/appropriately sized Power Supply SLC 5/03 processor (1747-L532) or SLC 5/04 processor ControlNet Scanner Module: 1747-SCNR ControlNet RS-232 Interface: 1747-KFC15 PC with 1784-KXTC15 or 1784-PCIC interface card Flexpak3000/Webpak3000 ControlNet Communications Board (915FK2101) Version Version 2.20 or later Version 2.25 or later Version 3.01 or later OS 301 or higher Any OS Version 2.20 or later Configuring SLC500 Applications 6-1

46 6.2 Network Configuration Configure the ControlNet network using RSLinx and RSNetWorx for ControlNet software. Using the parameters suggested in chapter 4 of this manual, configure scheduled traffic with RSNetWorx, by doing a scanlist configuration of the 1747-SCNR module to the drive. It is recommended that Input and Output files are used instead of M1 and M0 files, as discrete I/O is more appropriate for critical data transfer. Make sure keyswitch is in program position before download of configuration. Input address should be [ I:x:y ] with x = slot of SCNR module and y = 1 or greater. Output address should be [ O:x:y ] with x = slot of SCNR module and y = 1 or greater. Input and Output size for Flexpak3000 and Webpak3000 drives = 8. Important: Any address offset is limited by 31 words maximum minus the drive I/O word size. Figure 6.1 Network Configuration: Connection Properties 6-2 ControlNet Network Communication Option Board For Use With FlexPak 3000 and WebPak 3000 DC Drives

47 KFC15 Set Up Unlike PLC5 or ControlLogix controllers, the unscheduled messages between the SLC controller and the drive must pass through the KFC15 module and the serial cable, included with the KFC15 module, that physically connects the module and the processor. Important: ControlNet unscheduled messaging is not fully deterministic and may be further limited by the baud rate selected for Channel 0 (RS232/DF1) communications. The communication parameters between the SLC500 and the KFC15 must be identical. Set the DIP switches on the KFC15 according to the application. In most cases, choose all default settings. However, the value is preferable over the default value (1200) for Serial Port Baud Rate. In RSLogix5000, choose Channel Configuration in the project tree and verify that the General and Chan 0-System parameters are the same as you set on the KFC15 DIP switches. Figure 6.2 Channel Configuration: Chan 0-System Configuring SLC500 Applications 6-3

48 In the project tree, choose Controller Properties and Controller Communications. Set the appropriate Driver, Node and Path for Communications. The Node and Path must be the ControlNet Mode of the 1747-KFC15 module. After applying all settings, download to the processor.

49 6.4 Scheduled Messaging (I/O) To use scheduled messaging, the Ladder Logic must include a line that sets a bit in the SCNR module. The processor must be in run or remote run. Include a line that has a coil that sets word 0, bit 10 in the SCNR module. [O:x:0/10], where x = the slot number where the SCNR module resides. Output word 0 is the SCNR command word. Input word 0 is the SCNR status word. In the example below: O:3.3 had been set up as the output address and I:3.3 had been set up as the input address. There is a four (4) word offset in the discrete I/O Input. The drive appears to the processor as an IO rack with several modules, causing the Input offset. O:3.3 (Output register of the SCNR, word 3) shows the Word 0 - Drive Control Word. It is set to 3, meaning bits 00 and 01 (Run and Stop Not) are asserted and the drive is running. O:3.4 is Word 1 - Speed/Torque Reference. It shows the drive reference at 50% full speed. O:3.5 is Word 2 - Field Reference. If a Flexpak3000 is using a field current regulator kit option, this parameter must be set high enough to prevent a drive Field Loss Fault. I:3.7 is Word 0 - Drive Status Word (shown in decimal). Individual bits could be used for programming information. I:3.8 is Word 1 - Speed Feedback, which closely follows Output Speed Reference.
