I suppose you have in-use machine, it working good yesterday and gave you this alarm this morning. you can check the cable (MPI or Ethernet) to communicate from NCU to MCP and open the MCP back to see it have power (some led's on or flashing) possible MCP defective. attached page of this alarm from Siemens, it is always good you find Siemens Diagnostic Manual for 840D/840D sl
