Experimental Physics and
Industrial Control System

Hi, tech-talk,

I have a motion controller, and write driver support for it by model 3.

After power off, the pulse information and encoder counts of motor has been lost, and we want to save this informations.

The setPosition(double position) has been rewrote.（I think this method is used for autosave）

Through it, I can reset the pulse counts at any position.

$caput xxx.m1.SET 1

$caput xxx:m1.VAL 0

So I use autosave module, and save the .RBV and .VAL PV.

After IOC and controller restart, the .RBV and .VAL PV has been changed, But .RMP, .REP PV not changed and the register of pulse counts of controller also not change.

Have you met this case?

I would appreciated some suggestions.

Thanks
