P3: Basic PLC Program for SINUMERIK 840D sl
13.13 Block descriptions
MCP/HHU monitoring (840D sl)
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.
