Configuration
The configuration unit has three objects, a cir-

our and the open state with green colour. The
following inputs, indicators and outputs are
used:
- Circuit breaker;
input channel 2, indicator 110, controlled by
outputs OPEN (20) and CLOSE (21)
- Circuit breaker truck;
input channel 1, indicator 109, not controlled
- Earth-switch;
input channel 3, indicator 116, not controlled
The configuration commands are as follows:
S109:1,1,1,0,11
