Resolution
The following are the Niagara R2 link rules for inter-station and external station links:
- Link as many inputs to a single output as needed (“one-to-many”).
- For any input property that is already linked, no further link to it is permitted unless the property is a priorityArray type or trigger type (or certain types of Lon properties). Only then is a “many-to-one” link allowed.
- External links (between stations) have further restrictions. The following types of external links are not permitted (nor are they shown in the Link Editor):
- Links between prioritizedOutputs and priorityArray input properties.
- Links between properties using triggerType data species.
- Links from a GxText object to an internal property of another object (only inputs or outputs are available).
