Four concurring sequences can be defined with each up to 20 event and action pairs. The sequences are executed at the same time
but operate separately. For example, sequence 1 may have executed 3 actions, while sequence 2 still waits for its 1
st
event to occur.
In this example,
parameter 13-00 SL Controller Mode [0]
,
parameter 13-01 Start Event [1]
, and
parameter 13-02 Stop Event [2]
corre-
spond to sequence 1, sequence 2, sequence 3, and the like.

Illustration 69: Example of Events and Actions
Starting and stopping the SLC
Start and stop the SLC by selecting
[1] On
or
[0] Off
in
parameter 13-00 SL Controller Mode
. The SLC always starts in state 0 (where it
evaluates event [0]). The SLC starts when the start event (defined in
parameter 13-01 Start Event
) is evaluated as true (provided that
[1] On
is selected in
parameter 13-00 SL Controller Mode
). The SLC stops when the stop event (
parameter 13-02 Stop Event
) is true.
Parameter 13-03 Reset SLC
resets all SLC parameters and starts programming from scratch.
N O T I C E
SLC is only active in auto-on mode, not hand-on mode.
4.13.1 13-0* SLC Settings
Use the SLC settings to activate, deactivate, and reset the smart logic control sequence. The logic functions and comparators are
always running in the background, which opens for separate control of digital inputs and outputs.
