The function block and its parameters
Function block inputs
Description
(Bit)
EN 1: Activates the function block.
RE Reset
1: Resets the actual counter value back to zero.
D_ Count direction
1: down counting
0: up counting
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 ref-
erence value is greater than the operating hours
value, output Q1 will be set.
SV When there is a rising edge at SE, the value at
SV is applied as the operating hours value
