How do I inform SML to use the third light on a three light mast to indicate "secondary diverging"? ?Secondary diverging means route is through both crossovers.
I have used Logix to "force" a specific aspect when SML "wants" to display a different aspect. Conditionally, it looks at the displayed aspect and switch positions so that the "consequent actions" can only apply to a given route thru the plant.
From the "Browse" display. Note that only _two_ antecedent variables are marked as "Trigger C" (alculation?) - "Diverging Clear" and "Diverging Approach". The other antecedent variables (for the route information) are _not_.
And note that I've used a "mixed" Logic Operator. That means the Logic showm on each Antecedent Variable shows "AND", while that is NOT what the Logix actually does.
=========
IX:AUTO:1002C2 M134 to M122 - over-and-back - Restricting
Antecedent: (R1 or R2) and R3 and R4 and R5 and R6 and R7 and R8 and R9 and R10
[x] R1 IF Signal Mast "M134 Main EB" Aspect is "Diverging Clear"
[x] R2 AND Signal Mast "M134 Main EB" Aspect is "Diverging Approach"
[ ] R3 AND Turnout "BY1" state is "Turnout Thrown"
[ ] R4 AND Turnout "BYEX" state is "Turnout Thrown"
[ ] R5 AND Turnout "BYWX" state is "Turnout Thrown"
[ ] R6 AND Sensor "BY1V Switch Contact" state is "Sensor Inactive"
[ ] R7 AND Sensor "BY2V Switch Contact" state is "Sensor Inactive"
[ ] R8 AND Sensor "BY3V Switch Contact" state is "Sensor Inactive"
[ ] R9 AND Sensor "BY4V Switch Contact" state is "Sensor Inactive"
[ ] R10 AND Sensor "BY5V Switch Contact" state is "Sensor Inactive"
THEN
On Change To True, Set Signal Mast Aspect, "M134 Main EB" to Restricting

Sure, it's "not simple". But signaling rarely is!
