Caution
When you use the CP 243-2 module, you must disable analog filtering in the PLC.
If analog filtering is not disabled in the PLC, the digital point data will be destroyed,
and error conditions will not be returned as bit values in the analog word.
Ensure that analog filtering in the PLC is disabled.

Functions

The CP 243-2 is the AS-Interface master for the M1 master class, which means
that it supports all the specified functions. This makes it possible to operate up to
31 digital slaves on the AS-Interface by means of double address assignment
(A-B).
The CP 243-2 can be set to two different modes:
Standard mode: access to the I/O data of the AS-Interface slave
Extended mode: master calls (e.g. write parameters) or diagnostic value
request.

Designed for Industry

More flexible, more varied applications for the SIMATIC S7-200 thanks to the
significant increase in the available digital and analog inputs/outputs.
Reduced setup times because of the ability to configure at the touch of a button
Reduced downtime and service time in the event of an error thanks to the LED
displays:
- Status of the CP
- Display of all connected slaves and their readiness
- Monitoring of AS-Interface mains voltage
