3 Intrinsically Safe Remote I/O System System Overview excom is a remote I/O system for use in potentially explosive hazardous locations. It features bus-compatible, decentralized input and output modules in IP 0 housings that support discrete and analog intrinsically safe field devices. The modules are approved for use in Division, Zones and. The system consists of power supplies, gateways, I/O modules and a backplane. The backplane serves to distribute energy, transmit data and connect field devices. The power supply units ensure that reliable power is supplied to the entire system. A single power supply is sufficient for correct system operation. However, in order to enhance system availability, a second supply may be connected for redundancy. The gateways fulfill both master and slave functions: as a master they control the internal data bus and as a slave they communicate with the higher level fieldbus. Gateways control data communication between an I/O module and the process control system (PLC). The excom system may be configured with redundant gateways. The I/O modules act as interfaces to the intrinsically safe field devices. They receive intrinsically safe power from the supply units via the backplane. Up to I/O modules may be operated within a single backplane. Modules are easily connected: gateways, power supplies and I/O modules are simply plugged onto the backplane and latched. After the internal connections have been established, the peripheral components may be connected. The modules are hot-swappable. They may be plugged onto and removed from the backplane during operation in hazardous locations. When replacing faulty modules, the system automatically checks whether the previous module and the replacement are identical. The system supports substitute value programming. The internal cycle time of a fully assembled system is below ms (discrete processing; analog signals < 0 ms). The response time also depends upon the type of control system and fieldbus used in the application. If this is too long for some applications, it is possible to carry out direct assignments from inputs to outputs and to configure small function blocks within the system (PID in preparation). The system supports HART-compatible field devices; PROFIBUS-DP-V enables HART communication with the PLC.

4 Required Components for System Assembly In order to assemble a system, the following components are required as a minimum: () MT or MT9 or MT backplane () PSDEx power supply ( VDC) () GDP. PROFIBUS-DP gateway,. Mbps Then choose from the following discrete or analog input and output modules based upon the application: DF0Ex DO0Ex AIH0Ex AIHEx TI0Ex AO0Ex discrete input/output module for connection of NAMUR sensors and low voltage actuators discrete input module for frequency/counter function discrete output module for connection of intrinsically safe solenoid valves < W analog input module for connection of -wire transmitters with HART functionality analog input module for connection of -wire transmitters with HART functionality analog input module for connection of temperature detectors analog output module for connection of analog actuators PLC/SPC Connection excom may be connected to all systems withprofibus-dp interface (master functionality). In order to obtain access to the full range of functions, a PROFIBUS-DP master with V functionality should be used. Connections Bus: The MT backplane contains two 9-pole D-SUB connectors (redundant) and the MT and MT9 backplanes contain one 9-pole D-SUB connector for bus c onnection. Either copper cables conforming to PROFIBUS-DP specifications or fiber optics with matching transducers may be used. When mounting in a hazardous location, applicable precautionary measures must be used (see Installation Guidelines). Power supply: The standard backplane for Zones and features EEx e terminals for power supply connection. Modules: The modules are connected via two connectors ( poles / poles) with the backplane. Inputs/outputs: The backplane contains four -pole connectors per I/O module for connection to field devices. Several connection methods may be used, such as cage clamp terminals, screws, etc. Please consider the connection options when ordering components. Caution: All applicable regulations governing hazardous-location installations must be observed. TURCK Inc. 000 Campus Drive Minneapolis, MN Application Support: -00-TURCK-IS Fax: () -00

5 Intrinsically Safe Remote I/O System Diagnostics The gateway provides extended PROFIBUS-DP diagnostics, i.e. the full range of diagnostic data including channel-specific error indications. Each module is equipped with LEDs for field error indication. All I/O modules also feature LEDs for input/ output diagnosis and status indication. LED indications conform to NAMUR NE or DIN EN 00, i.e. Additional details are contained in the operating manual. green = operational readiness (power on/module function) red = error yellow = switching stat us of binary inputs/outputs Addressing The modules are addressed according to their physical location, thereby eliminating any need for manual addressing. A module inserted into slot 0 is assigned the internal address 0, a module in slot is assigned to address, etc. Three coded rotary switches are used to set the rack s PROFIBUS-DP address (maximum ). PROFIBUS-DP sees the system as a variable slave. Therefore, only the I/O modules physically present are assigned addresses by the PLC or process control system. Communication Rates / Cycle Times The PROFIBUS-DP master determines the system-specific communication rate. Admissible comm rates range from 9. to 00 kbps. The internal cycle time to process discrete signals is less than ms; to process analog signals requires less than 0 ms. The response time of the entire system largely depends on the number of PROFIBUS-DP nodes and the processing time of the higher level system. The general formula is: T R = x T I x T B x T PLS T R = response time; T I = internal cycle time Ex link; T B = cycle time of higher level bus; T PLS = cycle time of process control system.

6 Maximum System Extension PROFIBUS-DP allows no more than nodes to operate on one segment (including the master). The use of repeaters enables the operation of nodes with one PROFIBUS-DP master. Each segment may only be operated with the specified comm rate and maximum cable length. No more than four repeaters may be used on a network above 00 kbps. At 00 kbps and below up to seven repeaters may be used. The maximum cable lengths (without repeaters) depending on the communication rate are shown in the table below: Comm Rate Bus Segment Repeater Nodes (length of bus line) (max. number) (max. number) 9. kbps 9 ft (00 m) 9. kbps 9 ft (00 m) 9. kbps 9 ft (00 m). kbps ft (000 m) 00 kbps ft (00 m) Installation Guidelines excom is a remote I/O system to be installed in Division, Zone or Zone hazardous locations with intrinsically safe connections to field devices in Division or Zone 0 locations. The excom system communicates with a control system via PROFIBUS-DP. When using copper cables an approved segment coupler must be used. In this case, only ten excom systems may be used with one segment coupler. The use of fiber optics is also permitted. If redundancy is required, two gateways may be installed. The power supply is connected via EEx e (increased safety) terminals. The power supply may be installed and exchanged during operation. Please observe standard safety regulations regarding terminal connections. Field components such as sensors and actuators located in the hazardous location connect to the I/O modules via terminals. The modules are rated for connection to devices in Division or Zone 0 (protection type EEx ib[ia] IIC T) and provide secure galvanic isolation. Modules, sensors and actuators may be exchanged hot. If the system is installed in a hazardous location, suitable field housings are required. It is possible to order devices in appropriate field housings to ensure that the required protection type is fulfilled. All modules, the gateway to the higher level fieldbus and the power supply carry separate approvals. They may only be used in conjunction with approved backplanes.

It is intrinsically safe and may be installed in Division, Zone or Zone hazardous locations without additional protective measures. Copper cables or fiber optics (requiring additional module) may be used to connect the gateway to the PROFIBUS-DP network. When using copper cables an approved segment coupler must be used on the PROFIBUS-DP side to ensure explosion protection. The gateway may be configured for a maximum comm rate of 00 kbps. It does not feature a mechanical interface to the PROFIBUS-DP. Two standard miniature D-SUB connectors on the module rack connect the excom system to the bus. This arrangement allows gateways to be exchanged without interrupting bus communication and enables redundant system configuration. To reduce response times and facilitate control system operation, the gateway performs input and output assignment. A GSD file for system configuration is available from TURCK and included with each system. Redundancy: The use of two gateways and two bus lines ensures error-free, continuous communication. Should one of the gateways or bus lines fail, the other immediately takes over. GDP.

The gateway in slot is in stand-by mode and monitors data communication in both directions, i.e. data transfer to the PROFIBUS-DP master and to the I/O modules. Both gateways check their data for consistency. If variations exist, e.g. a bus line is disconnected or a gateway does not receive messages, the other gateway becomes active and generates an error indication via the PROFIBUS-DP.

19 Intrinsically Safe Remote I/O System The TI0Ex is a four-channel analog input module designed for connection to -, -, and -wire RTDs or thermocouples. PT00, PT000, and NI00 RTDs are supported, as well as types B, E, J, K, L, N, R, S, and T thermocouples. The module is approved for Zone / Division hazardous locations with connections to approved field devices or simple apparatus in Zone 0 / Division. No additional protective measures are required for connected field devices. Input compensation for -wire RTDs occurs on-line during initial operating parameter assignment. The module short-circuits the measuring circuit as well as the two additional terminals and automatically compensates for lead resistance. When using thermocouple inputs, PT00 resistors may be used across the two unused terminals of each channel for cold junction compensation. The resolution is bits, i.e. the analog value of 0- ma is represented as a number between 0 and. Data representation depends upon the type of control system used.

23 Intrinsically Safe Remote I/O System The AO0Ex is a four-channel analog output module designed for connection to intrinsically safe analog actuators. HART-compatible actuators may be connected and communicated with via an approved HART modem on the field side of the system. However, HART communications will not pass through the AO0Ex. The module is approved for Zone hazardous locations with connections to approved field devices in Zone 0. No additional protective measures are required for connected field devices. The resolution is bits, i.e. the analog value of 0- ma is represented as a number between 0 and 9. Data representation depends upon the type of control system used. Using any standard PROFIBUS-DP master and the system GSD file, it is possible to configure circuit monitoring, failsafe mode, and output range for the module. The software tool excom design or a PROFIBUS-DP master with V functionality enables the configuration of these parameters separately for each channel.

Up to discrete inputs/outputs or analog inputs/outputs may be connected in any combination. Modules may be exchanged during system operation without interrupting data communication (gateways and power supplies only in case of redundant system design). The backplane features a combined protection type of EEx m, EEx e and EEx i and is approved for installation in Zone / Division locations. The backplane is made of extruded aluminium sections for increased stability and ensured shielding. It is suited for wall mounting and 9 rail mounting. Modules receive power via the backplane. Supply energy is limited to levels suitable for Zone / Division (protection type EEx [ib] IIC). Therefore, modules can be exchanged during system operation. Other backplanes such as the MT9 and MT are available. The MT9 version supports one power supply, one gateway and up to eight I/O modules. The MT supports one power supply, one gateway and up to four I/O modules. Unlike the MT, the MT and MT9 are not designed to configure a redundant system with double gateways or power supplies.

27 Intrinsically Safe Remote I/O System The PSDEx power supply provides power to two gateways and a maximum of sixteen I/O modules. This equates to discrete inputs/outputs or analog inputs/outputs in any combination. The power supply features a combined protection type: EEx m, EEx e and EEx i and can be installed in Division, Zone or Zone hazardous locations. It is integrated into a protective aluminum housing and is fully encapsulated, eliminating the need for additional explosion protection measures. If the system is configured with redundant power supplies one of which malfunctions, it may be replaced without interrupting system operation. The PSDEx accepts - VDC. Each supply is connected to the backplane via Ex e terminals, which may not be accessed live. They are located under a protective cap and may only be accessed after suspending the supply voltage. Redundancy: It is possible to use two power supplies. If one of the devices or the incoming line fails, the second supply takes over as system supply. The supplies do not need to be the same.
