Process I/Os

Introduction

■Overview

A wide range of SIMATIC ET 200B, ET 200M, ET 200S, ET 200X and ET 200U 1) distributed I/O systems with a comprehensive selection of I/O modules is available for the AS 488/TM for the acquisition and output of process signals via sensors and actu- ators. The I/O modules of the ET 200M distributed I/O system specially tailored for process engineering are particularly rec- ommendable. The distributed I/O systems are connected to the automation systems via the PROFIBUS-DP fieldbus. Up to two PROFIBUS-DP lines with up to 122 stations each (max.

976 I/O modules) can be connected per automation system via IF 964-DP interface modules.

SIWAREX M function modules of SIMATIC S7-300 design can also be used in the ET 200M distributed I/O system for weighing and dosing tasks.

In addition, a large number of devices possessing a

DP interface can also be operated on the PROFIBUS-DP of the AS 488/TM. For example, DP interfaces integrated in the CPU modules of the SIMATIC S7-300 permit simple connection of slaves to the AS 488/TM. Using gateway modules on the PROFIBUS-DP (DP/PA link , DP/AS-i link, DP/DP coupler), ac- cess to the PROFIBUS-PA and AS-I fieldbuses and to the

I/O buses of SIMATIC PCS 7, S7-300, S7-400 or systems from other vendors is made possible.

The migration facilitates with the AS 488/TM automation system also permit existing TELEPERM M I/O modules to be connected via two I/O bus interfaces and used further.
