Function and communications modules
■ 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:
