Traffic Light Control
The implementation of a traffic light control requires following setup:
1. Define the function “Limit“ for digital output 1
2. Define the function “Traffic Light” for digital output 2
3. The setpoint values for both outputs have to be defined to the same value in such a way, that the
system can reliably detect an “Empty scale”
A functional setup switches the outputs as follows (vehicle scale example):
Action/Status
Output 1
(“Empty”)
Entrance
Exit
Output 2
(Weighing finalised)
Empty scale
A1 = 1
Green
Red
A2 = 0
Vehicle is on the scale
A1 = 0
Red
Red
A2 = 0
Weight recorded
A1 = 0

A2 = 1
