Function
Handles IN as a “good” status input if its status is “uncertain.”
Handles IN_LO as a “good” status input if its status is “uncertain.”
Handles IN_1 as a “good” status input if its status is “uncertain.”
Handles IN_1 as a “good” status input if its status is “bad.”
Handles IN_2 as a “good” status input if its status is “uncertain.”
Handles IN_2 as a “good” status input if its status is “bad.”
Handles IN_3 as a “good” status input if its status is “uncertain.”
Handles IN_3 as a “good” status input if its status is “bad.”
Reserved
There are options called “IN Use uncertain” and
“IN_LO Use uncertain” for the IN and IN_LO inputs.
When these options are valid, IN and IN_LO are
internally interpreted as “good” IN and IN_LO even if
their statuses are “uncertain.” (There is no option for
“bad” status.)
For the IN_1, IN_2, and IN_3 auxiliary inputs, there
are options known as “IN_i Use uncertain” and “IN_i
Use bad.” If these options are valid, an IN_i with
“uncertain” or “bad” status is internally interpreted as a
“good” IN_i.
* The exception is that if the input status is “Bad. Not
Connected,” INPUT_OPTS does not apply and the
input is considered “bad” as is.
A3.2.4 Relationship between the Main
Inputs and PV
The value and PV status are determined by the statuses
of two main inputs, INPUT_OPTS, and RANGE_LO
and RANGE_HI.
· If the statuses of two main inputs are both “good” or
anything other than “good”
See A4.2.1, Main Inputs.
· If only one of two main inputs has “good” status after
application of INPUT_OPTS, the PV value is
determined as follows:
· If the status of IN is “good” and that of “IN_LO”
is anything other than “good”
IN > RANGE_LO → PV = IN
IN  RANGE_LO → See A3.2.1.
· If the status of IN is anything other than “good”
and that of “IN_LO” is “good”
IN_LO < RANGE_HI → PV = IN_LO
IN_LO  RANGE_H → See A3.2.1.
