Default value: 0
Conversion index: 0
This parameter is read-only. Advanced interface counters from a built-in switch can be used for low-level troubleshooting. The pa-
rameter shows a sum of port 1 + port 2.
5.13 Parameter Group 13-** Smart Logic Control
Smart logic control (SLC) is a sequence of user-defined actions (see parameter 13-52 SL Controller 1 Action) executed by the SLC when
the associated user-defined event (see parameter 13-51 SL Controller 1 Event) is evaluated as true by the SLC. The condition for an
event can be a particular status, or that the output from a logic rule or a comparator operand becomes true. That leads to an associ-
ated action as illustrated:

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

Comparators Flip-Flops, timers, and logic rules are shared between sequences.
