EN
1: Activates the function block.

RE
Reset
1: Resets the actual counter value back to


D_
Count direction
1: down counting
0: up counting
Integer value range:
0…596 523
SE
When there is a rising edge at SE, the value at
SV is applied as the operating hours value and
appears at QV

(DWord) 
I1
The value at I1 is the reference value. If this
