*
Do not reset SLC Retains programmed settings in all group
13 parameters (13-*).
[1] Reset SLC Resets all group 13 parameters (13-*) to
default settings.
3.14.3 13-1* Comparators
Comparators are used for comparing continuous variables
(i.e., output frequency, output current, analog input, etc.) to
fixed preset values.
In addition, there are digital values that will be compared to
fixed time values. See explanation in 13-10 Comparator
Operand. Comparators are evaluated once in each scan
interval. Use the result (TRUE or FALSE) directly. All
parameters in this parameter group are array parameters
with index 0 to 5. Select index 0 to program Comparator 0,
select index 1 to program Comparator 1, etc.
13-10 Comparator Operand
Array [6]
Option: Function:
Choices [1] to [31] are variables that will
be compared based on their values.
Choices [50] to [186] are digital values
(TRUE/FALSE) where the comparison is
based on the amount of time during
which they are set to TRUE or FALSE,
respectively. See 13-11 Comparator
Operator.
Select the variable to be monitored by
the comparator.
