The counter is controlled via the internal gate (I-gate). The I-gate is the
result of logic operation of hardware- (HW) and Software-gate (SW), where
the HW-gate evaluation may be deactivated via the parameterization.
HW-gate: Input at Gate
x
-input at module
SW-gate: Open (activate): Output image Byte 12, set Bit 4 ... 6
depending on counter
Close (deactivate): Output image Byte 12, reset Bit 4 ... 6
depending on counter
The following states influence the gates:
SW-gate HW-gate influences I-gate
0 0 0
1 0 0
0 1 0
1 1 1
0 deactivated 0
1 deactivated 1
Gate function Abort and Interrupt
The parameterization defines if the gate interrupts or aborts the counter
process.
• At abort function the counter starts counting with the load value after
gate restart.

p

• At interrupt function, the counter starts counting with the last recent
counter value after gate restart.
