CP50M1 is a communication module with communication memory function and two
PROFIBUS DP interfaces (MPI interface only on X1).
Use cases include:
● Interfacing with distributed I/O devices and/or drives (master and/or slave function)
● Central commissioning of all CPU modules in the rack (MPI nodes)
● Buffer memory for data exchange between CPU modules
● Function for routing to other CP modules
● Connection of SIMATIC visualization components, e.g.: WinCC, or OP/TD
