excom® – Remote-I/O system for non-Ex and Ex areas

excom® is a remote-I/O system intended for use in Ex and non-Ex areas. The user not only profits from components that are optimized for these zones, but also from a standard concept to configure and parametrize the periphery and the field instrumentation. The modular sys-tem provides bus-compatible remote-I/O modules in IP20 for connection of binary and analog intrinsically safe and non-safe field devices. Depending on the de-ployed periphery, the system‘s Ex- pro-tection rating enables installation in zones 1 and 2. The field circuits are ap-proved for use in zone 0. Essential com-ponents of the modular system are pow-er supplies, gateways and I/O modules as well as the module racks for the compo-nents. The backplane is integ rated in the module racks. The backplane contains the connection layer for the field devices, from where power is distributed and data is transferred. The supply modules provide the entire system with power.

All modules are easily arranged: The gateways, power supply and I/O mod-ules are simply plugged on the module rack. All internal connections are thus es-tablished; only the periphery has to be connected. All modules can be plugged and removed in ongoing opera tion (hot swapping). The system auto matically checks whether the new module match-es the defined slot assign ment.

The excom® DTM (Device Type Manager) enables the user to operate the peri-phery and the field instrumentation di-rectly via the PROFIBUS network - inde-pendent from the higher level Master Class 1 control system. The integrated system-scan functionality makes com-missioning even faster and more failsafe. excom® also supports the connection of HART®-capable field devices. This allows continuous HART® communication via PROFIBUS-DPV1 up to the PLC; also auxil-iary HART® variables can be transmitted cyclically via DPV0 communication.

excom® – Remote-I/O system

excom® Remote-I/O – One system for all zones

The excom® remote-I/O system allows the user to freely select the location of installation. It can be installed in zones 1 and 2 and in the non-Ex area. The user not only profits from components that are optimized for these zones, but also from a standard concept to configure and parametrize the periphery and the field instrumentation. If this system is in-

stalled in zones 1 and 2, you can use our special power supply modules that gen-erate the intrinsically safe system volt-age. The interface to the fieldbus, here it is PROFIBUS-DP, is also intrinsic ally safe. A new module rack allows to operate up to 24 I/O modules in the non- Ex area and in zone 2, which further reduces the ba-sic costs for installation.

Plug and Play – also in ongoing operation

Hot swapping makes the excom® system a particularly user-friendly system: The system can be serviced and changed at any time. The I/O modules – including the power supply modules – can be plugged and unplugged in ongoing op-

eration, even in zone 1, without disturb-ing the field communication. This in-creases plant availability and saves time during commissioning and exten sion of system.

DTM-based – Online parametrization and configuration

With the new excom® -DTM and the ad-vanced gateway communication, the user can easily operate the periphery and the field instrumentation at any time via the PROFIBUS-network, with or with-out the higher-level Master Class 1 con-trol system. With the help of an FDT- frame such as PACTware™ all systems available on the PROFIBUS can be scanned and copied to the project tree

of the frame application. Then all peri-pheral modules and HART® field devices will be available online to the operator. The entire field wiring can thus be checked and the HART® field devices with their associated DTM diagnosed and configured. In this way, the field in-stallation is validated, before being transferred to the control system.



HART® – consistently parametrized from the PLC down to the field devices

excom® takes advantage of the world-wide applied HART® communication and allows field devices to be HART®-para-metrized via bus. The system transmits process and diagnostic data of the peri-phery and communicates, if necessary, with the HART® field instrumentation. This gives the control system additional

information on process values, diagnosis and asset management directly in digital form. Since the communication protocol allows the transmission of data over al-ready installed lines, the user can build, service and maintain the „last mile“ with little effort.

High availability – Redundant power supply and communication

The remote-I/O system excom® from TURCK has proven its worth in the pro-cess industry and the related high de-mands on equipment safety. The system allows a fully redundant setup of the power supply as well as of the communi-cation interfacing. Either 24 VDC or 230 VAC power supply is possible. As a standard feature, excom® also provides a

system-redundancy solu tion for the bus structure. This allows the redundant excom® system to be connected via re-dundant bus physics to a process control system with a PROFIBUS master. Thanks to the open standard, the redundancy system can be operated with any master available on the market.

System enclosure – Fieldbus system with full approval

TURCK offers an enclosure concept for the entire excom® system. The enclos ures are made of rugged stainless steel, fea-ture ignition protection type Ex-e and al-low installation in zone 1. In order to save the user the trouble of getting ap-provals for each system component, TURCK has obtained a single system ap-

proval for the stainless steel enclos ures with integrated module rack. All compo-nents used have been individu ally tested and approved. This makes customized solutions possible. Assembly and instal-lation take place at TURCK in order to en-sure that the required clear ance and creepage distances are met.

excom® – Solutions for the Ex area

The excom® series allows the user to free-ly select the location of installation. It can be installed in zones 1 and 2 and in the non-Ex area. The user not only profits from components that are optimized for these zones, but also from an integrated concept for configuration and paramet-rization of the periphery and the field in-strumentation. A uniform Ex-i peri phery supports the processing of signals and the control of field devices from the zones 0, 1 and 2. If this periphery is in-stalled in zone 1 and 2, you can use our special power supply modules that gen-erate the intrinsically safe system volt-age, in order to capture the signals as

close as possible to the instrumentation. The interface to the fieldbus, here it is PROFIBUS-DP, is also intrinsically safe. Because of its configuration, the entire system can be services in ongoing opera-tion when installed in the Ex area. The enclosures used so far in zone-2 excom® installations, now have free space avail-able for additional components such as valve terminals or load switches. Since a special gateway safeguards the Ex-i peri-phery against the bus, a separate seg-ment coupler is not needed to imple-ment the intrinsically safe RS485-IS bus physics.

excom® – Remote-I/O systemModules for intrinsically safe circuits

I/O module, digital, 8-channel

The I/O module DM80Ex is used for the connection of NAMUR sensors (DIN EN 60 60947-5-6) and actuators. When wire- break or short-circuit monitoring are activated, mechanical contacts can only be connected with a corresponding resistor circuitry (WM1, Ident no. 0912101).

The module features protection class Ex ib IIC and can be mounted in zone 1 in combination with excom®.

The explosion protection category of in-puts/ outputs is Ex ia IIC.

When connecting the fieldbus devices, care has to be taken that all inputs and outputs share a common potential.

Input and output mode can be adjusted via the PROFIBUS-DP master. The follow-ing parameters can be adjusted: switch-ing behaviour, switch-on delay, substi-tute value, wire-break and short circuit monitoring.

The user can furthermore determine whether an input or an output should be provided at the connecting point. The following configurations are possi-ble: 8 inputs/0 outputs; 6 inputs/2 out-puts up to 0 inputs/8 outputs (GSD- file, Mode 2). This guarantees optimal adap-tation to the corresponding application environment.

Frequency module, 2-channel

The input module DF20EX is equipped with 8 channels according to NAMUR, which are divided into two blocks. There is one frequency input per block and three control inputs/outputs.

The module features protection class Ex ib IIC and can be mounted in zone 1 in combination with excom®. When con-necting the fieldbus devices, care has to be taken that all inputs and outputs

share a common potential. The explo-sion protection category of inputs/ out-puts is Ex ia IIC.

The module can be used as a counter or a frequency module: It is thus suited for pulse counting of binary input signals or frequency measurements of binary pulse sequences of NAMUR sensors.

The counting direction can either be set externally via a control input or internal-ly by setting a parameter. The maximum frequency of one block is 4 kHz; with 2 blocks the frequency is reduced to 2 kHz.

Input and output mode can be adjusted via the PROFIBUS-DP master. Each chan-nel is equipped with parametrizable wire-break/short-circuit monitoring.

Input module, analog, 4-channel

The input module AI401Ex is designed to connect 2-wire transducers (active in-put = source mode / transducer passive) and 4-wire transducers (passive input = sink mode / transducer active).

The module features protection class Ex ib IIC and can be mounted in zone 1 in combination with excom®. The field cir-cuits feature protection class Ex ia IIC resp. Ex iaD.

The field circuits are galvanically sepa-rated from each other.

HART®-compatible transducers can be connected to the module. The field de-vice can thus be parametrized directly at the terminals on the DIN rail with a li-censed modem. An additional imped-ance in the circuit is not necessary.

The measuring range is digitized in the scope of 0…21 mA. For clear reading, the digitized value is spread to 0 … 21000 (independent of the para-metrized measuring range) and trans-mitted to the host system.

Potentiometer module, 4-channel

The analog input module AI43Ex is de-signed for the connection of potentiom-eters in 3 or 4-wire technology. If 3-wire potentiometers are used, the terminals at the module rack have to be bridged. Resistance measurements, hence the analysis of potentiometers with a 2-wire connection, are not possible.

The module has four field circuits to control 3 or 4-wire potentiometers. The field circuits are galvanically separated from the power supply, from the inter-

nal bus and from each other. The mod-ule features protection class Ex ib IIC and can be mounted in zone 1 in combi-nation with excom®. The explosion pro-tection category of the inputs is Ex ia IIC.

Each potentiometer input is monitored for wire-break, whereby single as well as multiwire-break of the four connection lines per input is reliably detected. Short-circuit monitoring is not carried out. In case of a line error, the para-metrized substitute value is immediately

output and the output value is set to ‚in-valid-bit‘. This state is maintained until valid measured values are provided again.

The resolution is 14 bit. For clear read-ing, 0…100% is spread to the digitized value 0 … 10000 (independent of the parametrized measuring range) and transmitted to the host system.

Output module, analog, 4-channel

The output module AO401Ex is de-signed for connection of intrinsically safe analog actuators such as control valves or process indicators.

The module features protection class Ex ib IIC and can be mounted in zone 1 in combination with excom®. The explo-sion protection category of the outputs is Ex ia IIC resp. Ex iaD.

The outputs are galvanically separated from each other.

HART®-compatible transducers can be connected to the module. The field de-vice can thus be parametrized directly at the terminals on the DIN rail with a li-censed modem. An additional imped-ance in the circuit is not necessary.

The host system transmits a digitized control value 0…21000 (independent of the parametrized measuring range). This raw value is then transformed by the AO401Ex into a signal between 0…21 mA.

Input module, analog, active, 4-channel, HART®

The input module AIH40Ex is designed to connect 2-wire transducers (active in-put = source mode / transducer passive).


The inputs are not galvanically separat-ed from each other. When connecting the field devices, care has to be taken

that all inputs share a common potential.

HART®-compatible sensors connected to the module communicate with the inte-grated HART® controller.

The resolution is 14 bit, i.e. the analog value between 0…21 mA is represented as a number between 0 and 16383. For clear reading, the digitized value is spread to 0 … 21000 and transmitted to the host system.

Up to 8 HART® variables (max. 4 per channel) can be read via the cyclical PROFIBUS data traffic. The bidirectional exchange of variables between the host system and the HART® transmitter is im-plemented via PROFIBUS-DPV1.

Parameters like wire-break or short- cir-cuit monitoring, measuring range, HART® communication etc., can be ad-justed for each channel separately and are solely initialized by the PROFIBUS master.

The output module AOH40Ex is de-signed for connection of intrinsically safe analog actuators such as control valves or process indicators.


The outputs are not galvanically sepa-rated from each other. When connect-ing the field devices, care has to be tak-en that all outputs share a common potential.

HART®-compatible actuators connected to the module communicate directly with the HART® controller.

The resolution is 13 bit, i.e. the analog value of 0…21 mA is represented as a

number between 0 and 8191. For easier operation, the host system operates in a value range between 0…21000. This raw value is reduced by the AOH40EX to a 13-bit resolution.

Parameters such as line monitoring, sub-stitute value etc. can be adjusted for each channel separately and are initial-ized solely by the master.

The input module TI40Ex is used for the connection of 2, 3 and 4-wire tempera-ture probes of the types Pt100, Pt200, Pt500, Pt1000, Ni100 and Cu100, as well as for the connection of thermocouples of the types B, E, D, J, K, L, N, R, S, T and U. The module can also be used for the measurement of low voltages (-75…+75 mV, -1.2…+1.2 V) and resistance measurements (0…30 Ω, 0…300 Ω, 0…3 kΩ)

The module features protection class Ex ib IIC and can be mounted in zone 1 in combination with excom®. The explo-

sion protection category of the inputs is Ex ia IIC.

Line compensation of 2-wire tempera-ture resistors is done by means of para-metrized resistance values. These values have to be determined first through measurements.

When using thermocouples, external cold junction compensation can be car-ried out separately for each channel by connecting resistors such as the Pt100 to the two unused terminals. Internal compensation instead is parametrized

for all channels via an integrated Pt100 resistor.

The internal resolution is 16 bit, the analog value is represented as a number between 0 and 32767 on the PROFIBUS- DP. The temperature is indicated in Kel-vin. For conversion to °C, please observe an offset of 273.2.

excom® – Remote-I/O systemGateway for installation in zones 1 and 2

PROFIBUS-DP interface

The GDP-IS gateway serves to connect the excom® system to PROFIBUS-DP net-works. Connection to the PROFIBUS- DP is established via optical fibers or copper cables. When using optical fibers for data transfer an optocoupler pair must be installed between wired and optical PROFIBUS which also adapts the level to the IS layer. When using copper cables a segment coupler (RS485-IS coupler) must be installed to ensure explosion protection.

The gateway can be operated at a maxi-mum transmission rate of 1500 kBaud. The bus is connected to a standard min-iature SUB-D slot on the module rack.

A GSD file containing all configuration files and parameter sets is available for system configuration. When connected to suitable host systems, you can change the system configuration during operation.

The gateway provides the entire range of PROFIBUS diagnostic functions in-cluding port-related diagnostics. Addi-tionally, manufacturer-specific error codes are generated. These can be HART® communication errors, power supply errors, planning errors as well as information on simulators, internal com-munication and redundancy status.

Redundancy: The use of two gateways and two bus cables ensures error-free communication, in case one gateway or one bus line may fail. If one of the com-ponents fails, the other immediately takes over (module racks MT18… only), this is called line redundancy. System re-dundancy (two masters, each with its own segment coupler connected to a gateway) is also supported.

excom® – Remote-I/O systemPROFIBUS network components

PROFIBUS-DP segment coupler

The PROFIBUS-DP segment coupler SC12Ex from TURCK has been devel-oped for intrinsically safe PROFIBUS connection.

Equipped with one RS485 and two RS485-IS interfaces, this coupler is suited for many Ex-area applications. The RS485-IS interface is entirely realized ac-cording to the PNO PROFIBUS guideline. The coupler can thus supply both lines of the TURCK Ex-Remote I/O system excom® simultaneously (line redundan-cy). Just one device is required for Ex-separation and line redundancy.

The segment coupler SC12Ex is IP20 rat-ed, suited for mounting in the non-Ex area and can be supplied redundantly. Both power supply inputs are decou-pled by diods. The load distribution de-pends on the level of operating voltage. Operating voltage 18…32 VDC.

In switch position 0, the coupler identi-fies the baud rate automatically. Addi-tionally, the start-delimiter occurences of the PROFIBUS telegrams are evaluat-ed. Three consecutive and valid start-de-limiter occurences have to be received before identification locks in.

All received telegrams are checked for plausibility by means of start-delimiter sequences. Baud rate detection is start-ed after reset. If telegrams are not re-ceived within 1.7 seconds, baud rate search is activated. Alternatively, the baud rate can be adjusted via rotary switch.
