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.
Single digital inputs, not fail-safe

Green Continuous
light
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.
DI 2y
– Off
Green Continuous light Both output lines y+ and y- have no signal

Description, cause
LED x+1 NC contact / NC contact
Red Different signal states at inputs x and x+1
– No signal at input x and no signal at input x+1
NC contact / NO contact
Red Identical signal states at inputs x and x+1
– No signal at input x and a signal at input x+1
LED x+1 NC contact / NC contact
Green One signal at input x and one signal at input x+1
Green NC contact / NO contact
A signal at input x and no signal at input x+1
Description, cause
No signal at digital input x (x = 20..23)
Signal at digital input x
Description, cause
Output y (y=0 .. 3) has a signal
One of the two output lines y+ or y- or both lines of output y have a
signal
