Outline of operation
● This counter can increment (up count) or decrement (down count) depending on the ON/OFF
state of the relay specified by the up/down input.
● The count operation is incremental counting (+1) when the up/down input is ON, and
decremental counting (-1) when the up/down input is OFF. The elapsed value is stored in the
[CEn] area.
