SIMATIC ET 200MP /S7-1500 Communication Modules
CM PtP: Serial communication via point-to-point connection
Interfaces for communication via PROFINET and in part PROFIBUS DP as well are already integrated in the S7-1500 CPUs.
Communication modules increase the communication capabilities of the S7-1500/ET 200MP providing additional communication functions or more interfaces.
Communication modules enhance flexibility and performance of automation solutions using the SIMATIC S7-1500/ ET 200MP. Additional interfaces enable realization of complex automation structures or process optimization through connection to the enterprise management level.
Within a decentralized architecture with SIMATIC ET 200MP PtP Communication Modules are employed, the serial interfaces can be used to connect e.g. barcode or RFID readers for non-contact data transmission.
Four communication modules are available for connecting automation components via serial interfaces.
-
Connection of legacy and external systems possible
-
Connection of data readers or special sensors
-
Can be used centrally and in decentralized ET 200MP peripheral system
-
Variety of physical interfaces, e.g. RS232 and RS422 or RS485
-
Predefined protocols, e.g. 3964(R), Modbus RTU or USS
-
Application-specific protocols based on Freeport (ASCII)
-
Uniform programming interface for all modules
-
Diagnostics alarm for simple fault remediation
