5 MPI Communication
5.4 Machine control panel (MCP)
Machine control panel (MCP)
Machine control panel front side; example: Version T (turning machine)
Prerequisites for start-up
In order to start up an MCP, the following hardware is required:
MPI bus cable
The MCP is connected to the SINUMERIK 840Di through the MPI bus. A termi-
nating resistor for the MPI bus is not integrated in the MCP.
Programming device (e.g. PG740)
A programming device is required for the SIMATIC Manager STEP7 as the plat-
form in order to match the basic PLC or PLC user program to the requirements
of the appropriate automation system with regard to the operation of an MCP
and to load it then into the PLC.
A programming device is not required if the SIMATIC Manager STEP7 is
installed on the SINUMERIK 840Di.
How to install additional software is described in Chapter 15, page 15-455.
In order to start up an MCP, the following software is required:
At least MCP firmware version 4.1.5 is required. The version number can be
checked when the MCP powers up.
Basic PLC program
The MCP relevant modules of the basic PLC program are FB 1 (MCP commu-
nication parameters), FC 19 (interface parameter assignment version: milling)
and FC 25 (interface parameter assignment, version: turning).
