Trigger assistance

[mrogers-9898]

Is it possible to have Triggers, A, B, C set up like....

C is Problem when A and B are Problem.

C stays Problem, even if B goes OK

C goes to OK (from Problem) only if And B are OK

a picture of what I'm trying to achieve...



thanks in advance...

It is. Here is some pseudo-code of the top of my head that shows how I think you need to do it:

({TRIGGER.STATUS}=0 & ({TRIGGER-A.last()}>0 & {TRIGGER-B.last()}>0)) | ({TRIGGER.STATUS}=1 & ({TRIGGER-A.last()}<1 & {TRIGGER-B.last()}<1))

Note: I'm assuming A + B fire with a non-zero value. It's illustrative.

I have a query about your logic though. You say that C will fire when A and B fire. But you say that C will stay in a problem state when A OR B is in a problem state. Wouldn't the expression make more sense like this:

({TRIGGER.STATUS}=0 & ({TRIGGER-A.last()}>0 | {TRIGGER-B.last()}>0)) | ({TRIGGER.STATUS}=1 & ({TRIGGER-A.last()}<1 & {TRIGGER-B.last()}<1))
