Fail value using indicators

[GADPS]

HI,

I am using several indicators binding to shared variables from differents sites and i need to know how to show a fail value (like "-5" for example) in case the variable is not available. 

For my application (monitoring system) is a problem to show the last value or zero value because it is a valid value.

It is clear I can do the programming to change the value but I think LV has a configuration option in somewhere.

Thansks !

You could substitute NaN. You could also use a string indicator to show the formatted number ("2.45") if available, or some custom text ("not available", empty string, etc.) if not. You could even show both, such as "2.45 (stale)" or similar.
