1.7.2.3.1 Intended Purpose
The CS31 bus module DC551-CS31 can only be used together with the AC500
CPUs and dedicated PS501 control builder.
The CS31 bus module is used as a decentralized I/O module on CS31 field buses. The bus
connection is performed on a RS-485 serial interface, which allows the connection of this
module to all existing CS31 buses. In addition, the CS31 bus module provides 24 I/O channels
with the following properties:
● 8 digital inputs 24 VDC in one group (2.0...2.7)
● 16 digital inputs/outputs in one group (3.0...4.7), of which each can be used
● as an input,
