Hi Mark

 

The HVPS is controlled via stream device, I attached the protocol file and the template database.

Hi Abdullah,

 

Is the code for the HVPS available on GitHub or somewhere else we can see it? We might be able to spot the problem.

Hi

 

We have an IOC to control two types of devices using stream device, a high-voltage PS from matsusada and a current pre-amplifier from SRS. The problem is that when typing exit on the IOC shell the IOC does not exit, so I tried excluding devices from the IOC and it seems the problem is with the HVPS, when excluded from the IOC it exits normally and restarts under procServ. I enabled asyn masks using asynTraceMask and asyntraceIOMask, even after the exit the IOC is doing IO with the device with no problem. I was using asyn 4.30 and stream 2.8.16 I think so I pulled the latest version of all drivers and still the same behavior.

 

Best Regards,

Abdalla.
