The counter is controlled by the internal gate (i gate). The i gate is the
result of logic operation of hardware gate (HW gate) and software
gate (SW gate), where the HW gate evaluation 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 reset-
ting SW_GATE of the SFB 47
The parameterization defines if the gate cancels or stops the counter
process.
n At cancel function the counter starts counting with the load value
after gate restart.
