Thank you Abdalla – the protocol file will be very useful and maybe help to augment Martin’s work. There’s lots of useful code from both of you and will considerably shorten our development time.

Hi

 

We are using the Gamma QPC for the storage ring and the beamlines. The control is simply done using Stream Device. It works fine but you might get a timeout every couple of hours. Seems like there is a problem with the controller itself. We are controlling it through Ethernet so you might want to try the serial port or ModBus.

Attached is the protocol file we are using for voltage and pressure readings and the channel enable/disable functions. Setpoints and relays control was not required, it is done through the Agilent XGS600 gauge controller.

 

Dear Martin,

 

As I mentioned, we are facing a timeout issue with these controllers, are you facing a similar issue with your solution?

 

Best Regards,

Abdalla.

One of our staff has been working on QPC support.  I am not sure what functionality he has reached beyond monitoring.  I have included him on this message.
