An error entry is also made in the PLC alarm buffer for timeouts. resulting in the following
error messages on the HMI:
• 400260: MCP 1 failure
• 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.
