using S7-200 PLC for this case...
Heres my problem...
I have 2 NORMALLY OPEN Push Buttons
PB1 is I0.0
PB2 is I0.1
PB1 and PB 2 are connected in parallel.
lamp is Q0.0
If I make I0.0 normally Open -l l- and I0.1 normally close -l/l-
will the light on even if I dont press any of the two?? (just confuse about the "examine if On & Examine if Off".)
Heres what i Think...
the light will light... due to I0.1 -l/l-
am i right guys?![Person playing handball :person_playing_handball: 🤾](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f93e.png)
