Hello Lifang, We’ve been looking at available options of interface equipment to EPICS using serial protocols for the Diamond project. A summary of this work was presented at the last EPICS meeting by Pete Owens http://www.jlab.org/intralab/calendar/archive02/epics/talks/owens.pdf It includes links to the serial support we have been using. We are looking to standardise on StreamDevice for simple protocols ie not requiring a checksum and ORNL serial for more complex protocols. Regards. Mark -----Original Message-----
From: Lifang Zheng [mailto:[email protected]] Sent: 02 December 2002 08:34 To: EPICS tech-talk Subject: device support routines for RS232 Dear all,
I am developing the device support routines for RS232 Varian
Multi-Gauge controller. I use the drivers drvIpac, drvVipc616.c and tyGSOctal.c.
Before getting any response(value) from the controller it has to send some
commands and I hope to use standard records ai/mbbi/stringin/stringout
instead of writing a new record. How to attach the string command("#aa02cnt") in
Ai record field to read the pressure? Is it possible that I can share somebody's
experience in order to find a suitable way?
Any suggestion are appreciated,
Lifang |
