6 Communication with the PLC

The I20 has 10 galvanically isolated (opto coupled) inputs and 5 galvanically isolated (opto
coupled) outputs.
6.1

PLC inputs

If different functions are performed at the same time, an fault message will be generated.
The following functions are possible:
1. Measurement Start / Stop
2. System test (gap control sensors)
3. Program switching
4. Clear 2-sheet / Clear 0-1-2-wa outputs
5. Zero adjust (not active by default)
6. Material detection NF (with first selected sensor)
7. Teach-In 1-sheet (not active by default)
8. Teach-In 2-sheet (not active by default)
9. Reset Fault
