ET 200M - IM 153-1/153-2

Overview

z For connecting ET 200M as slave to PROFIBUS DP (via copper conductors)

z IM 153-2 can also be used in redundant PROFIBUS DP systems with the S7-400H, software redundancy and the S5-155H

z With time stamp functionality and time-of-day synchronization

z Suitable for synchronous operation

Application

The interface module IM 153-1 / IM 153-2 HF is needed for connecting an ET 200M modular I/O station to the PROFIBUS DP fieldbus via copper

conductors.

These headers can therefore be used in the widest possible range of applications.

Fault tolerant systems

In the main, fault tolerant systems are used where no plant stoppage is allowed, such as in energy generation, energy distribution, power stations or

chemical engineering. In conjunction with the fault tolerant

S7-400H (redundant CPUs) the ET 200M can be connected in one-way mode (normal availability) or switched mode (increased availability).

Additionally the IM 153-2 can be used not only in applications with software redundancy but also with the S5-155H.

Fail-safe systems

When an error occurs, fail-safe PLCs go into a safe state and protect the safety of people, machines and the environment, for instance in the case of

presses, automated systems or personal transport. Various ET 200M signal modules are available for the purpose of connecting fail-safe signals to the

S7-300F or S7-400F/FH, and provide SIL 2 or SIL 3 depending on the type of connection.

Range exposed to explosion hazard

There are various digital and analog modules for use as intrinsically safe versions for the explosion hazard range, such as in chemical engineering and

pharmaceuticals or on drilling platforms. They support the processing of signals carried on electrically isolated channels from Ex-zone 1. There are also

analog modules with HART capability.

Highly dynamic production processes

Distributed solutions for controlling high speed machines in production and machining processes with high precision are becoming increasingly important,

for instance for automatic speed control. In such cases the time between the capture of a signal by the decentralized I/O equipment and the

corresponding reaction at the actuator must be as short as possible and precisely reproducible. Synchronous connection of a SIMATIC automation

solution to the isochronous PROFIBUS in this way is known as "clock synchronization" and is supported by various ET 200M signal modules.
