In addition, an error entry is generated in the diagnostics buffer of the PLC,
resulting in the following error messages on the operator interface:
• 400260: MCP 1 failure or
• 400261: MCP 2 failure
• 400262: HHU failure
In this case, the input signals from the MCP or from the handheld unit (MCP1In/ MCP2In or
BHGIn) are initialized with 0. If it is possible to resynchronize the PLC and MCP/HHU,
communication is resumed automatically and the error message reset by the BP.
