Error Register in the Digital Module | Siemens CP 243-2 manual

Interface to the User Program in the S7-200 CPU

2.3.2Error Register in the Digital Module

Meaning for the User Program

This register always supplies the value º0º. The CP 243±2 reports errors using the error register in the analog module (see Section 2.4.2).

Example of Access to the Error Register

If the CP 243±2 is inserted directly beside the S7±200 CPU, SMB9 constantly supplies the value º0º.
