Process I/Os

■Overview

Special function and communications modules can be operated in the ET 200M I/O systems connected to the AS 488/TM auto- mation system via PROFIBUS-DP. These include:

•SIWAREX M function module with weighing and dosing elec- tronics for implementation of scales and for controlling dosing units

The AS 488/TM automation system additionally requires the SIWA driver block for this function module. See the section on SIWAREX M for further information and ordering data on the SIWA driver block.

•CP 343-2 communications processor for linking the AS-I field- bus

See section on DP extensions for AS 488/TM for information on configuring and diagnostics.

Note: It is also possible to use the CP 342-2 communications processor (which is no longer available) instead of the CP 343- 2.

•FM 350-1 single-channel counter module

The AS 488/TM requires special driver blocks for operation of the FM 350 counter module.

These can be obtained on request from: I&S IT PS, Karlsruhe
