The CM 1542-5 communications module expands the SIMATIC S7-1500 controller to include a PROFIBUS connection for communication with lower-level PROFIBUS devices in bandwidths from 9.6В kbps to 12В Mbps. The module can also be used to implement separate PROFIBUS lines, in other words, to control a number of different field devices via a number of PROFIBUS segments. The CM 1542-5 assumes all communication tasks, thus reducing the CPU workload.

The CM 1542-5 is suitable for S7 communication as well as for conventional PROFIBUS communication. This makes it possible to establish communication between the S7-1500 controller and other devices, for example those from the SIMATIC S7-300/400 range.

• PROFIBUS DPВ master or DP slave with electrical interface for connecting the SIMATIC S7-1500 to PROFIBUS at up to 12В Mbps (including 45.45В kbps)
• Communication services:
  • PROFIBUS DP
  • PG/OP communication
  • S7 communication
  • Open user communication (SEND/RECEIVE) via FDL
• Time synchronization
• Simple programming and configuration over PROFIBUS
• Cross-network PG communication using S7 routing
• Module replacement without a PG
• Data record routing (PROFIBUS DP)
• Adding or modifying distributed I/O during operation
