13-12 Comparator Value
Array [6]
Range: Function:
Size related* [-100000.000 -
100000.000 ]
Enter the ‘trigger level’ for the
variable that is monitored by
this comparator. This is an
array parameter containing
comparator values 0 to 5.
Application
dependent*
[-100000.000 -
100000.000 ]
Enter the ‘trigger level’ for the
variable that is monitored by
this comparator. This is an
array parameter containing
comparator values 0 to 5.
3.14.4 13-1* RS Flip Flops
The Reset-Set Flip Flops hold the signal until set/reset.
Par. 13-15
RS-FF Operand S
Par. 13-16
RS-FF Operand R

Two parameters are used and the output can be used in
the logic rules and as events.

The two operators can be selected from a long list. As a
special case, the same digital input can be used as both
Set and Reset, making it possible to use the same digital
input as start/stop. The following settings can be used to
set up the same digital input as start/stop (example given
with DI32 but is not a requirement).
