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 through 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 Moules 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
