Try to switch input signals and try the operation of the output M100.
Explanation of learning points- When an input signal is received, the signal of A contact turns on.
- When no input signal is present, the signal of B contact turns ON.
- After M100 signal turns ON, signal is held by itself.
- You can also try to see if you can release self-holding after M100 is on.
Even if the first and third lines of the signal are turned off after M100 signal has been turned on, the M100 remains on.
