Good day everyone,
I have a question about SmartTag.
In the RS program, I search using the SearchL\SStop instruction and use the collision sensor, so everything goes well. The simulation will run correctly.
But in the part of the program I search using the Search_1D pEX1 instruction and here it does not detect the same part for me and the simulation does not work.
SearchL uses doFr1TouchSense
Search_1D uses doFr1SensorRef
Does anyone have experience with this?
In the signal analyzer, in the simulation, the output doFr1SensorRef does not switch to 0 after contact.
