Hi EPICS folks,Has anybody developed a EPICS module to communicate with the OMRON PLC SYSMAC CJIM CPU12-ETN using Ethernet TCP/IP sockets? I'm prepared to develop such a module using the asyn framework, but wanted to check if anybody has done this already. We use the OMRON PLC for cryogenics and vacuum control for our bionanoprobe X-ray fluorescence instruments. I see references to Omron PLCs on the EPICS website from Paul Hamadyk and Mauro Giacchini, but only for RS-232 communications. Has anybody developed a EPICS module for RS-232 communications with CryoCon temperature controllers? Again I'm prepared to develop such a module using the asyn framework, but wanted to check if anybody has done this already. Thanks,Jay Steele Xradia Corporation
Jay,I've got a driver that I've been using for years with no problems. Uses the FINS protocol over TCP/IP (not using asyn). It originally came from KEK, but I did some modifications to it since then.
