Inputs x+1 (DI 1+, 3+, .. 19+) can be set individually via parameter p10040 (TM54F).
p10040 (TM54F) = 0: Input x+1 is an NC contact.
p10040 (TM54F) = 1: Input x+1 is an NO contact.
Factory setting: p10040 (TM54F) = 0 for all inputs x+1.

F_DO y (0+..3+, 0-..3-)
Green
Continuous
light
Output y (y=0 .. 3) has a signal
–
Read back input DI 2y for output F_DO y (y = 0..3) for test stop.
The state of the LEDs depends on the type of external circuit.
