Posted 19 May 2016 (edited) Hello community.I'm beginner in programming and PLCs. .I'm trying to make a C # connection to a PLC by RS 232 (software: CX-Programmer) OMRON. Since the added OCXs lying on the CX Server Lite (for example: axPLCSetup, axPLCError, axIOTable, and axPLCClock librarias), however, cant make the connection. Already googled a lot but can not find what I need.If anyone can help me with this problem, grateful. Edited 19 May 2016 by Miguel9Eduardo Share this post Link to post Share on other sites
