Activate test mode (p10041)
A check mark at an F-DI defines whether the pair of digital inputs is to be integrated in the
forced dormant error detection test of the assigned power supply (L1+ or L2+) (for additional
information, refer to the chapter "Forced dormant error detection", under Extended
Functions).

Signal source for F-DO (p10042 - p10045)
An AND element with 6 inputs is interconnected with each output terminal pair of an F-DO;
the signal sources for the AND inputs can be selected:
● No signal source (input set to logical HIGH; default)
● Status signals of the drive of drive group 1 to 4
Test selection F-DO (p10046 [0..3])
The test stop for forced dormant error detection can be activated for each F-DO by means of
a pull-down menu (for additional information, refer to the chapter "Forced dormant error
detection", under Extended Functions).
