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 NO contact.
Factory setting: p10040 (TM54F) = 0 for all inputs x+1.
Single digital inputs, not fail-safe
DI x –
Green
Fail-safe digital outputs with associated readback channel
F_DO y Green
(0+..3+,
0-..3-)
Readback input DI 2y for output F_DO y (y = 0..3) at test stop.
The status of the LEDs also depends on the type of external circuit.

Status
Continuous Same signal states at input x and x+1
light
– No signal at input x and no signal at input x+1
NC contact / NC contact
Continuous One signal at input x and one signal at input x+1
light
NC contact / NO contact
Continuous One signal at input x and no signal at input x+1
light
Off No signal at digital input x (x = 20..23)
Continuous Signal at digital input x
light
Continuous Output y (y=0 .. 3) carries a signal
light
Off One of the two output lines y+ or y- or both lines of
output y carry a signal
Continuous Both output lines y+ and y- carry no signal
