Hello,
We are developing an embedded application to communicate with a PLC. The plan is to use CodeSys UDP communication. I mean, using "Network Variables".
As far as I know, the communication protocol is called as "3S protocol". Does anybody have the details of the protocol ?
Thanks in advance
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
