Subject: EPICS support for OMRON PLC SYSMAC CJIM CPU12-ETN Ethernetcommunications? CryoCon RS-232?

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
