Re: PyDevice support VAL field remains 1

[Vishnu Patel via Tech-talk <tech-talk at aps.anl.gov>]

Hi,

It was my mistake.

I was returning 1 each time execute python code, which was reflected in the VAL field of ao record.  Now VAL value has been returned in the python code.

The problem has been resolved.

Thanks all

Vishnu

Subject: PyDevice support VAL field remains 1

 

Hi,

     I have developed IOC using PyDevice.  The ao recored works functionally with python code., but VAL field remain 1 and RVAL change according to the PV set value.  is any additional setting required in the IOC / record field / python code?
