An error entry is also made in the PLC diagnostic buffer for timeouts (bits 10 and 27),
resulting in the following error messages on the MMC:
• 400260: MCP 1 failure
Or
• 400261: MCP 2 failure
• 400262: HHU failure
An MCP or HHU failure is detected immediately after a cold restart even if no data have yet
been exchanged between the MCP/HHU and PLC.
The monitoring function is activated as soon as all components have signaled "Ready" after
powerup.

Relevant parameters (FB1):
Communication between the PLC and HHU is implemented through configuring and
subsequent loading of SDB210 (Global Data). To allow the basic program to access the
HHU data and implement HHU failure monitoring, the addresses set via global data must be
declared in FB1 parameters.
