The Lens States in the Indicator tool are controlled by the three fields: Lens Output1, Lens Output2, and Lens Output3 (these are located under the Values property for the indicator tool).
These three fields provide a binary pattern that corresponds to a particular Lens State with Lens Output1 being the LSB and Lens Output3 being the MSB.
For example, if the fields evaluate as Lens Output1 = True, Lens Output2 = False, Lens Output3 = True, this corresponds to the binary pattern 101 which equates to 5 and thus Lens State 5 will be the active one.
So, how do I control the Lens state with a numeric value 0 through 7 then? This simply requires a little logic added to each field. If my tag is called "TagName" then:
The Value for Lens Output1 would be: TagName & 1
The Value for Lens Output2 would be: TagName & 2
The Value for Lens Output3 would be: TagName & 4
This will apply a bitwise AND function between the tag value and the bit we care about for each field. So if my TagName contained the value of 5, the above logic would provide the TRUE, FALSE, TRUE pattern we want (101) and thus Lens State 5 would be active.
Note - you can edit the appearance of each Lens state under the Appearance section of the Indicator properties.
