1)
When using 2DO-relay 35 V, 6DR2801-8A (S22 = 3), only DO3 and DO4 are available.
2)
At S**=0 there is no assignment, the digital outputs are then 0 and can be set at S85 = 2 by the SES.
3)
Assignment of different control signals to one digital output causes an OR-function.
4)
Message signal active tracking mode see page 1 11.
