Up/Down Counter Example Using Discrete Status Bits
In the following example, if X2 and X3 are off, when X1 toggles from off to on the counter will
increment by one. If X1 and X3 are off, the counter will decrement by one when X2 toggles
from off to on. When the count value reaches the preset value of 3, the counter status bit will
turn on. When the reset X3 turns on, the counter status bit will turn off and the current value
will be 0.
Up/Down Counter Example Using Comparative Contacts
In the following example, when X1 makes an off to on transition, counter CT2 will increment
by one. Comparative contacts are used to energize Y3 and Y4 at different counts. When the
reset (X3) turns on, the counter status bit will turn off, the current value will be 0, and the
comparative contacts will turn off.
