2.14. Parameters: Smart Logic Control2.14.1. 13-** Prog. FeaturesSmart Logic Control (SLC) is essentially a sequence of user defined actions (see par. 13-52 [x])executed by the SLC when the associated user definedevent (see par. 13-51 [x]) is evaluated asTRUE by the SLC. Events andactions are each numbered and linked together in pairs (states).This means that whenevent [0] is fulfilled (attains the value TRUE),action [0] is executed. Afterthis, the conditions ofevent [1] will be evaluated and if evaluated TRUE,action [1] will be executedand so on. Only oneevent will be evaluated at any time. If anevent is evaluated as FALSE, nothinghappens (in the SLC) during the current scan interval and no otherevents will be evaluated. Thismeans that when the SLC starts, it evaluatesevent [0] (and onlyevent [0]) each scan interval.Only whenevent [0] is evaluated TRUE, will the SLC executeaction [0] and start evaluatingevent [1]. It is possible to programme from 1 to 20events andactions.When the lastevent /action has been executed, the sequence starts over again fromevent [0] /action [0]. The illustration shows an example with three event / actions:Starting and stopping the SLC:Starting and stopping the SLC can be done by selecting .On [1]. or .Off [0]. in par. 13-00. TheSLC always starts in state 0 (where it evaluatesevent [0]). The SLC starts when the Start Event(defined in par. 13-01Start Event) is evaluated as TRUE (provided thatOn [1] is selected in par.13-00). The SLC stops when theStop Event (par. 13-02) is TRUE. Par. 13-03 resets all SLC pa-rameters and start programming from scratch.2.14.2. 13-0* SLC SettingsUse the SLC settings to activate, deactivate and reset the Smart Logic Control.13-00 SL Controller ModeOption: Function:[0] * Off Disables the Smart Logic Controller.[1] On Enables the Smart Logic Controller.FC 300 Programming Guide 2.
