MCP/HHU monitoring (840D)
The following alarms are displayed at HMI in cases of errors for the communication with the
machine control panel (MCP):
• 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 reset to 0. If it is possible to resynchronize the PLC and MCP/HHU,
communication is resumed automatically and the error message reset by the GP.
