Hi all, We are using a Siemens ET200SP PLC with a CPU 1510SP . This PLC will be integrated into a control environment using Tango. I would like to know if anyone in the Tango community has already developed a Device Server doing the communication with this type of PLC ? The Siemens standard protocol is Profinet. Thanks for reply. Cordially, JCM |

Hello, Do you really require Profinet communication or Modbus would suffice? There is indeed already a modbus device developped by the community (https://www.tango-controls.org/developers/dsc/ds/318) and ModbusPLC device (https://www.tango-controls.org/developers/dsc/ds/1089/) exist. The first one have been tested on Siemens PLC at our side and was proven functional.

If you prefer Python over Cpp for the Tango Device Server, I can share some code. We have done some communication there with pymodbus to read and write bits in a PILZ PLC via Modbus from a linux PC. |
