Hello,
Hi Gabriele!
I need to use calcout with input from other IOCs. It seems to me that in the FLNK field of the records from the other IOC I have to add .PROC or perhaps CP (Not clear to me from various documents I found). I guess I can try all possible combinations.
Is there any similar rule for the INPA, INPB etc in the calcout record? Can I just use NPP, for instance, of is there anything else I need to do?
If you wish to force processing from records in the "input" IOCs, you could have their FLNK fields set to "<your_calcout_record>.PROC CA", as documented in [1]. However, that leads to very undesirable coupling between IOCs (since they have to be aware of every IOC which depends on their PVs), so I'd say that the best course of action is using "<input_pv> CP" in your INPx fields, which mean the calcout record will be processed every time a monitor event from any of the input links arrives [2].
Cheers,
Érico
Best wishes
