MVP 2021 Flex727 Posted May 10, 2016 MVP 2021 Report Share Posted May 10, 2016 Anyone ever tried to communicate with a Unitronics PLC using a SECS/GEM interface? Any suggestions on the best way to go about doing that? I'm really only needing the lowest level of communication where a host queries the PLC to get a few bits of data. The PLC would remain in listen mode only. Quote Link to comment Share on other sites More sharing options...
