Communication module CM 1242-5; for connection of SIMATIC S7-1200 to PROFIBUS as DP slave module
- The CM 1242-5 provides the communication services for integrating an S7-1200 into an automation solution as a PROFIBUS DP slave.
- PROFIBUS DP slave:The CM 1242-5 works as a DPV1 slave in accordance with IEC 61158, handles data traffic completely autonomously, and thus relieves the CPU of communication tasks.
- The data areas of the distributed I/Os are transferred consistently between CP and CPU.
- Extensive diagnostic options are available via STEP 7, including
- Operating state of the CM
- Generl diagnostics functions
- Connection diagnostics
- Message buffer
