Posted 16 Sep 2019 (edited) Hi all, I would like to ask you about the name and manual of the command protocol for PLC Siemens. I am not asking about communication protocols, I am asking about the protocol of the commands to use some features of the PLC without TIA Portal. In a similar way, OMRON is using the protocols FINS and Hostlink, or Mitsubishi is using MELSEC commands. Thank you very much.
