Experimental Physics and Industrial Control System
Hi,
we are trying to move a motor and then stop it using EPICS sequencer
code and motor record.
The state code dials the desired location into the VAL field via pvPut()
and makes
the motor move. If the user requests the motion to be aborted during the
motion, the
state code attempts to stop the motor either using STOP field or SPMG
fields. And for some reason this does not work. Actual change of the
SPMG field to
"Stop" only happens when the motor motion is complete, and setting
STOP field to 1 from the state code does not have any effect.
But if either moving the motor is done using caput to the VAL field or
the stopping the motor is done via caput to the STOP or SPMG fields, it
works. What is
the reason for such a behavior? Is this expected? Any advice would be
appreciated.
We are using motorR6-8 and seq-2.1.12 for this with R3-14-12-3 on RHEL6.
Thanks,
Hovanes Egiyan.
