Experimental Physics and Industrial Control System
My Doubt is about the processing of a pasive Record with an input Link PP, with another passive record connected to. In point 1. and 1.3 in the EPICS Record Reference Manual comes information related to it. I understand that every passive record is processed when I change its VAL. e.g., I've got the next record in my Db
record(ai,inp0){
field(SCAN,"Passive")
}
...then I run the IOC, and every time I change the VAL, (e.g., with caput command: caput inp0 124) , I can see with camonitor command that the PV value is changing.
Now we connect this Record to the next record:
record (calc,calcinp){
field(SCAN,"PAssive")
field(INPA," inp0 PP")
field(CALC,"A+45")
}
What I understand from reference manual, is that a passive record with a PP Link (in this case calcinp) with another passive record connected to (in this case inp0), is processed if the other record (inp0) is processed, and I can make inp0 to be processed executing the command "caput inp0 198".
But the result is that every time I change the value of inp0 with the caput command, the calcinp record is not processed...why?
Thanks for the answers
