I just started programming with TwinCat v3 OOP.
I’m currently working on a warehouse that has several conveyors, they all have the same functionality to transport materials.

I was wondering what would be the best architecture to avoid GVLs. I have created FBs for conveyance and sensors but not sure how to linked them without using GVLs.

I have conveyors 1, conveyor 2 and conveyor 3 running in one PRG and Photo Sensor1-3 running on another program.

If I instance these conveyors locally I won’t be able to access them from the sensor program and viceversa.

Could interfaces work for this? Researching about interface at the moment but not sure if this will work. Maybe I will have many instance of interfaces…..
