Note
The MCP 483C IE is connected via an Ethernet interface of the PCU. Since the
communication of the MCP with the SINUMERIK PLC is based on Windows components,
the MCP monitoring time may be exceeded in the following cases:
• 1. Cause: Windows XP identifies a fatal exception error (blue screen)
Possible measure: none
• 2. Cause: Impairment of Ethernet communication through unsuitable PC components.
Possible measure: Increase in MCP monitoring time (parameter: MCPxTimeout)
