I am interested in the Modbus UDP, and we did a program in a small controller for Modbus/TCP. Only just found out the IO Scanning by Schneider uses UDP.
Anyone document on this Modbus/UDP or know where to find? Our working program for Modbus/TCP lose connection when we send a reply to the IO Scanning.
Modbus/UDP need to be in connected state like the TCP? Same port number 502?
Hope you can help?
