ET 200M

The following types of I/O modules can be operated in ET 200M systems on AS 488/TM automation systems:

•Standard S7-300 signal modules

•I & C I/O modules with enhanced diagnostics capability

•Ex input/output modules

DP driver blocks are assigned to the modules when configuring with PROGRAF AS+/NT or ASBEDIEN.

The I & C modules with diagnostics capability offer channel- based fault displays, internal module monitoring, diagnostics alarms, or the freezing of the last value or connection of a default value upon failure of the CPU or the load power supply. They recognize channel faults and module-internal faults, and can signal these events to the AS 488/TM automation systems where they are made available at a user interface for further evaluation.

■Overview

The ET 200M modular I/O system with degree of protection IP 20 can be extended by signal modules and function modules of the SIMATIC S7-300 automation system. The wide range of modules means that it is suitable for individual or complex automation tasks.

The ET 200M is a passive station (slave) on the PROFIBUS-DP fieldbus. Communication via the bus system is by means of the master interface module in the automation system and the

IM 153 interface module (IM 153-1, IM 153-2 or IM 153-2 FO). The ET 200M I/O system has diagnostics functions for:

•Module faults

•Short-circuit of outputs

•Bus faults, i.e. faulty data transmission

•DC 24 V load power supply

•Hot swapping of I/O modules.

Diagnostics data are evaluated decentrally using diagnostics LEDs on the ET 200M, or centrally by means of the CPU in the automation system (station-specific or code-specific diagnos- tics). All acquired diagnostics data are additionally available at a diagnostics interface.

The ET 200M can be operated with two types of design:

•Design with bus connectors

•Design with active bus modules (swapping of modules possi- ble during operation).

The ET 200M comprises:

•IM 153 interface module for connection to PROFIBUS-DP

A connection to PROFIBUS-DP with fiber-optic technology is possible via integral interfaces on the IM 153-2 FO or via addi- tional OLMs (optical link modules) or OBTs (optical bus termi- nals).

•Various I/O modules connected by means of bus connectors, or plugged onto active bus modules.

•A power supply if necessary.

The modules are mounted on a DIN rail. The arrangement is set during the hardware configuring with COM PROFIBUS.
