6.2.1
CP51M1 is an Industrial Ethernet interface with buffer memory function. It can be used for
the following applications:
● Exchange of process data with other CP51M1 and SIMATIC Industrial Ethernet modules
(e.g. CP443-1)
● Visualization of process data in WinCC
● Visualization of messages in WinCC
● Exchange of process data with third-party systems (e.g. process computers)
● Central commissioning and diagnostics of all CPU modules in the rack
● Buffer memory for data exchange between CPU modules
● Time synchronization for uniform system time
