The MPI (multi-point interface) is a module for connecting custom made opera-
tor panels to a SINUMERIK 840Di.
To this aim, the module provides 3 I/O interfaces with a total of 64 digital outputs
with C-MOS level (5V).
Start-up of an Interface MPI module is to a large degree identical to start-up of a
machine control panel (MCP), Section 5.4, page 5-140.
Therefore, only the differences from an MCP start-up are explained below.
The MPI module's electrical connections and connections for MPI communica-
tion are made using the interfaces on the rear side of the module.
