5.6.6 Counter - Additional functions5.6.6.1 OverviewThe illustration shows how the additional functions influence the counting behavior. Thefollowing pages describe these additional functions in detail:5.6.6.2 Gate functionn Starting, stopping and interrupting a count function of counter 0 to counter 2 exclu-sively happens via the SW gate by setting the SW gate of SFB 47.n Starting, stopping and interrupting a count function of counter 3 happens via theinternal gate (I gate). The i gate is the result of logic operation of HW gate and SWgate. The HW gate evaluation of the connection ‘Gate 3’ may be deactivated by theparametrization. With a de-activated HW gate evaluation the triggering exclusivelyhappens by setting the SW gate of SFB 47.The parametrization defines if the gate interrupts or aborts the counter process.n At abort function the counter starts counting with the load value after gate restart.Schematic structureFunctionGate function abort andinterruptVIPA System SLIODeployment I/O peripheryCounting > Counter - Additional functionsHB300 | CPU | 013-CCF0R00 | en | 19-30142
