Communication with PLC devices by the Siemens company

The Siemens company produces more types of devices with more communication possibilities.

- Climatix regulators:
Climatix regulators (POL63x) support communicaion by the Modbus protocol (RTU or TCP) directly or by communication modem (POL902).
For this communication in the PROMOTIC system can be used:

- Frequency inverters:
- Frequency inverters Sinamics G120 with CU240S PN control unit use the PROFINET communication interface. This interface is also used by another Sinamics G and S series inverters(S110, S120, S150 ...).
- Frequency inverters Micromaster use the PROFIBUS communication interface.

For communication of the PROMOTIC application with both devices can be used: PmS7 - Driver for communication by the S7-TCP/IP protocol.
Example: For Sinamics G120 for the PmS7 communication driver can address for example:
- DB20,REAL0 = current requested frequency before the spinup time, is read only
- DB1040,REAL0 = requested speed of motorpotenciometer
- DB947,W0 = inverter malfunction code
