Because all of other piezo controllers in my facility have motor record interface,

and some features based on EPICS records use motor record.

Searching "Piezosystem Jena NV 40/1 CLE" will get you link to user manual of this piezo controller.

I have experience developing Model 3 motor driver fo Kohzu Aries motor controller and nanoFAKTUR EBD060310 piezo controller.

Before coding, I would like to know if you EPICS mates have related experience for such a simple device.

The mentioned poll() function needs to find out,
where the positioner is - in closed loop.
If it is homed/referenced/calibrated.
That code needs to be somewhere,
either you use streamDevice or a proper model 3 driver.
In streamDevice you set up db files, which may feel easier
for some people.
The model 3 driver involves some C/C++ coding.
Please let me know, if you want help here.
