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
Basic and High Feature Modules with various interfaces:
