3.13.1. 13-** Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user defined actions (see par. 13-52 [x]) executed by the SLC when the associated user defined
event
(see par. 13-51 [x]) is evaluated as TRUE by the SLC. Events and
event
[0] is fulfilled (attains the value TRUE),
action
[1] will be executed and so on. Only one
during the current scan interval and no other
each scan interval. Only when
events actions
from 1 to 20 and
event action
When the last / has been executed, the sequence starts over again from
event / actions:
Starting and stopping the SLC:
Starting and stopping the SLC can be done by selecting
The SLC starts when the Start Event (defined in par. 13-01
stops when the Stop Event (par. 13-02) is TRUE. Par. 13-03 resets all SLC parameters and start programming from scratch.
