Inputs x+1 (DI 1+, 3+, .. 19+) can be set individually via parameter p10040 (TM54F).
1)
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.

Readback input DI 2y for output F_DO y (y = 0..3) for test stop.
The status of the LEDs also depends on the type of external circuit.
