BI: Fct digital output 1
Defines the source for digital output 1.
NOTE
The brake relay can also be controlled
from another digital output (if this is
available) or using a distributed I/O
module. Analog to DOUT 1, it should
be guaranteed that the I/Os are
controlled by the status bit “MHB
active”.
Inverting digital
outputs
This parameter allows the signals
to be output to be inverted.
