The counter is controlled by the internal gate (i gate). The i gate is the result of logic oper-
ation of hardware gate (HW gate) and software gate (SW gate), where the HW gate eval-
uation may be deactivated by the parameterization.
HW gate:
open (activate):
Edge 0-1 at hardware gate
x
input of the
module
close (deactivate):
Edge 1-0 at hardware gate
x
input of the
module
SW gate:
open (activate):
In application program by setting
SW_GATE of the SFB 47
close (deactivate):
In application program by resetting
SW_GATE of the SFB 47
The parameterization defines if the gate cancels or stops the counter process.
