Hello Patrick,
There is EPICS motor record support for the Newport ESP300.
From the VxWorks shell, if you enter;
dbior "drvESP300"
you should get something like this;
Driver: drvESP300
ESP300 controller 0 port = 'asyn port name', address=0, ...
value = 0 = 0x0
If you enter;
dbl "motor"
you will see a list of all the motor records in your IOC.
You can determine what kind of motor controller is
connected to each motor record by looking at the
"DTYP" field of each motor record. For example,
if a motor record is called "abc:m1", then enter
dbgf "abc:m1.DTYP"
at the VxWorks shell. This information is also
displayed from the standard medm display distributed
with the motor record.
Hope this helps,
Ron

Hi,
I'm trying to control a rotation stage connected to a Newport
Universal Motion Controller / Driver, Model ESP300, connected to a
Linux box by a Comtrol DeviceMaster RTS. Is there device support
available for this? I have inherited a database and SNL code which
runs on a VME box. I believe it uses C calls to open a device file and
control the ESP300. I am now trying to move it over to a Linux box,
but I'm new to EPICS. I've gone through some of the documentation, and
watched some of the introductory talks, but I'm still not quite sure
how to do this. My impression is, someone changes a process variable
in the MDM screen, and this triggers an appropriate record to be
processed. I'm not sure how the SNL comes in however, or what happens
when a record is processed. Any help would be very welcome.
Thank you for your time.
