BACnet How to build an object name (AIx) using a variable's value

Programming Examples

Hi everyone,

I’m setting up the BACnet Instance Number so the user can enter it dynamically, instead of hardcoding it in the script.

This works fine when I use a fixed number:

10 VAR2 = 421AI5

But I need that “421” to be the value the user enters into VAR1, something like:

20 VAR3 = VAR1AI5

This line doesn’t throw an error, but it doesn’t work as expected either (it doesn’t take VAR1’s value as part of the object name).

Is there a way to concatenate or build the object name dynamically from a variable? Some kind of indirection function for this case?

Thanks in advance.
