Hello Torsten,
Sorry for the delay. Thank you very much for the advice.
Your solution worked. The controller does not reboot as expected by not
sending the "reset" command and it connects without problems.
The only issue that I noticed is that the .RBV values does not update
after reboot. Everything comes back to normal if I try to move a motor
or just process the motor record by sending the 1 to .PROC. Any idea why?
I will take a look into that, but it is safe to say that my original
problem is solved.
Thanks for the quick fix.
Answering your question about why booting the IOC: we are still under
development phase and I am trying the best combination of initial and
autosave settings for those records to guarantee a successful come back
in case of future issues/reboots. Any shared expertise will be highly
appreciated :)
Best,
Nilson

Hej Nilson,
I don't have a Phytron controller, so I can't test.
But trying to be helpful:
You can actually try t remove the reset command in the driver.
motorApp/PhytronSrc/phytronAxisMotor.cpp
Remove these lines:
//RESET THE CONTROLLER
sprintf(this->outString_, "CR");
phyStatus = sendPhytronCommand(this->outString_, this->inString_,
MAX_CONTROLLER_STRING_SIZE, &response_len);
if(phyStatus){
asynPrint(this->pasynUserSelf, ASYN_TRACE_WARNING,
"phytronController::phytronController: Could not reset
controller %s\n", this->controllerName_);
}
//Wait for reset to finish
epicsThreadSleep(10.0);
And see what is happening ;-)
Out of curiosity:
Why do you need to reboot the IOC ?

Dear all,
I have a Phytron stepper controller (I1AM01) with 16 axis with
incremental encoders, and I using EPICS Motor module to control all axis
since it supports this controller.
I noticed that the IOC for that specific model resets the controller on
connection (IOC boot). The reset erases the count on all encoders
forcing me to "home" all 16 axis again every time I have to reboot
the IOC.
Is there a way to avoid this controller reset at IOC boot time to avoid
loosing the encoder counts? Anyone using this controller that could help
me with the settings?
Versions:
- EPICS Base R3.15.5
- asyn R4.31
- autosave R5.7.1
- motor-R6-9
Best regards,
Nilson
