All SIMATIC Control Automation Systems communicate on an open bus system called PROFIBUS DP or an open Ethernet system called PROFINET.The SIMATIC ET 200MP and S7-1500 Systems are open-type programmable controllers used for solving automation tasks.The systems consist of several modules,which can be assembled as analog or digital input or output modules.The S7-1500 System contains a CPU Module in place of the interface module,which allows for a higher level of function and control.All modules are designed to be used with both systems.
