ET 200S

ET 200S

■Overview

The ET 200S is a bit-modular distributed I/O system with degree of protection IP 20. The bit modularity of the ET 200S permits op- timum, rapid adaptation to the respective automation task. The setting-up times can be minimized even with frequently chang- ing demands by replacing or combining various I/O modules. The range of I/Os includes analog and digital signal modules, process modules and consumer feeders (modules for switching and protecting three-phase consumers up to 5.5 kW).

The ET 200S has a design with independent wiring, i.e. the wir- ing is carried out using terminal modules which function as a supporting system for power modules, electronics modules and consumer feeders. The terminal modules are latched onto a rail according to EN 50 022 and can be prewired and tested without I/O modules. This design also supports hot swapping of

I/O modules.

■Design

The following components are available for the ET 200S distrib- uted I/O system:

•Interface module to connect the ET 200S to the PROFIBUS-DP (IM 151 or IM 151 FO), or alternatively

•IM 151/CPU or IM 151/CPU FO with additional integrated CPU 314 for preprocessing of process data

•Terminal modules for DIN rail mounting including terminals (keyed connection system permits increased vibration resis- tance of 5 g); rail system for power modules, electronics mod- ules and consumer feeders

•Power modules for electronics modules and consumer feed- ers;

for monitoring and fusing the load and sensor power supplies, and for monitoring the auxiliary voltages for a group of consum- er feeders

•Electronics modules: analog and digital I/O modules, as well as special process modules (e.g. for recording SSI sensor val- ues, or for universal counter functions)

•Consumer feeders (modules for switching and protecting any three-phase consumers up to 5.5 kW)

-Direct starters

-Reversing starters

Configuration limits when used on AS 488

Up to 32 modules can be inserted per I/O system.

The maximum address range of all inserted I/O modules is

122 byte for input data and 122 byte for output data. This limit is irrelevant to the CPU version.

The maximum number of parameters is limited to 244 byte per station. Process modules such as the counter module have long parameter sets, permitting the parameter limit to be reached pri- or to the limiting length of the process data.

■Configuration

Configuration and parameterization

The ET 200S distributed I/O systems are configured and param- eterized using COM PROFIBUS.
