The CM 1542-5 communication module expands the SIMATIC S7-1500 Controller to include a PROFIBUS connection for communication with lower-level PROFIBUS devices in bandwidths from 9.6 kbps to 12 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 handles all communication tasks, thus reducing the CPU load.

Apart from classic PROFIBUS communication; the CM 1542-5 is also suitable for S7 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 DP master or DP slave with electrical interface for connecting the SIMATIC S7-1500 to PROFIBUS at up to 12 Mbps (including 45.45 Kbps)
• Communications services:
  • PROFIBUS DP
  • PG/OP communication
  • S7 communication
• 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
