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
