5 MAKING USE OF MODULES
(c) Stop input
• In the case of model LWC400:
The stop input function of the model LWC400 disables the input of pulse signals by the
counter module when the stop input signal is turned on.
When it is turned off, the function enables the input.
• In the case of models LWC401 and LWC402:
The stop input function of the models LWC401 and LWC402 disables the input of pulse
signals by the counter modules when the stop input signal is turned on.
When it is turned off and a preset-start is made using an appropriate control code
(described later in this section), the function enables the input.
(d) Comparison output
The comparison output function outputs the result of comparison of a comparison data
value (R) and a count value (C).
The comparison operation performed is one of the following:
• R > C
• R < C
• R = C
In the last comparison operation above, the result will be held until the latch is reset by
setting a control code.
