4.7.7 Operating the X136 interface as MPI
Applications
The X136 interface can also be operated as an MPI interface instead of a PROFIBUS DP
interface. The typical (default) baud rate is 187.5 Kbaud. A baud rate of up to 12 MBaud can
be
set for communication with other CPUs. It should be noted, however, that a rate of 12 MBaud
is not supported by all CPUs (e.g. smaller SIMATIC S7 CPUs).
The following list provides examples of when using MPI (multi-point interface) may prove
effective:
● If a PC/PG is being used with an MPI interface
● If an OP/TP only has an MPI interface
(newer devices have PROFIBUS or PROFINET interfaces)
● If SIMOTION and SIMATIC CPUs are coupled via XSEND / XRECEIVE
