Experimental Physics and
Industrial Control System

Hello everyone,

My name is Tony and I’m a student at Idaho State University.  I’ve been doing a senior project to help establish an EPICS control system for the Idaho Accelerator Center.  I have been trying to create a control system specifically for a Nemic-Lambda ZUP (20 V 10A) magnet power supply.  

So far, I have hooked the power supply into one of the ports of a MOXA 6650-8 terminal server using a RS485 (4wire) cable.  Then I sent commands to the port with telnet 134.50.3.107 4002 to change the current, display the model name, and so forth.  One example of a command that I use is:

:ADR01;:MDL?;

which serves as both an initialization command and displays the make and model of the power supply which has address 01.  Now, the next step is to figure out a way to turn those commands into process variables that I can monitor or change with MEDM. 

So, I found a paper called “How to create EPICS device support for a simple serial or GPIB device” written by W. Eric Norum.  Since the power supply is a kind of serial device I figured that it would be pretty close to what I need to do.  However, I’m a little confused as to what to do in my situation on one part. 

In the paper there’s a section called “Create a new device support module”, which shows how to create an EPICS application using the makeSupport.pl script.  In the paper, after he creates a directory, he runs the command:

/home/EPICS/modules/soft/asyn/bin/linux-x86/makeSupport.pl –t devGpib AB300

So, my question is: since I’m not using a GPIB device can I still use this kind of command?  Would I have to change the devGpib part of the above command to something else?  I was thinking that since there is a file named devGpib.dbd that maybe that has something to do with the command above.
