Dear EPICS developers/users!

I've been using EPICS for almost two years and there has been a number

of occasions when I've seen a need for this solution, but I have always

found a way around it. However, I would really like to know a good

solution exist.

Setup:

Let's suppose that we have a black box device that hosts EPICS records

and we can't modify its EPICS database.

This device hosts a record "blackbox:A".

On another IOC, we would like to process a record "IOC:B" every time a

"blackbox:A" processes, even if it doesn't change value.

My idea was that I could somehow detect a change in "blackbox:A.PACT"

and trigger an interrupt, but I just can't get it to work.

Has anyone tried to solve this situation before?

Best regards,
Jan Malec
