hi, 

I want to use aSub record to implement some logic by modifying the myAsubProcess function in dbSubExample.c file.

My aSub record file is like this:

field(OUTA, "PS1:SETI CPP") 
field(NOVA,"1") 
field(FTVA,"FLOAT")  
in myAsubProcess function, I can assign the value to OUTA field, for example:

*(float*)precord->vala= value_xxx

OUTA filed will drive a PV in streamdevice driver which communicate to a power supply through ethernet.

My question is: if I want to measure the time from the beginning of aSub record is processed to the end of the value is set to power supply correctly? (if the value is set correctly, the power supply will ack)

Thanks a lot for you help. 

 

 

Best wishes
