Uses of the Module

DP Slave and AS-i Master
The CP 243-2 module can be operated in the S7-200 programmable controller. It
allows the attachment of an S7-200 to the AS-Interface (as AS-i master). Both
interfaces can be used independent of each other.

System Integration and Structure
The accompanying product information lists the CPUs with which the CP 243-2
can be operated.
From the point of view of the S7-22x CPU, the CP 243-2 represents two expansion
modules (an 8DI/8DO digital module and an 8AI/8AO analog module).
The design of the CP 243-2 corresponds to that of a standard expansion module
for an S7-200.
