10-4 Examples of a final output conditions ladder circuit

(1) Circuit for keeping the external output ON until the next external trigger is received
External trigger input
External output
(2) Circuit for controlling the ON time of the external output using the timer
External trigger input
External output
(3) Pipeline control
If the interval between triggers is too close to the total measuring time on a non-stop
conveyor line, the time allowed for outputting the measurement result is reduced, and the
external device will not receive the measurement results.
In this case, a pipeline control type of circuit should be created, so that the external
device can receive the measurement results in the next cycle.
