Interval Macros - Best Practices?

[bradturnbough]

I started to look into the use of Macros for Item update interval's.

Is is possible to MULTIPLY a macro so that I can use it in a trigger expression?

For example:

{$MACRO100} === 60s

Item check interval == {$MACRO100}

Trigger === max(item, {$MACRO100}*3)=0


Is this possible?

No, this will not work.
