(5) The judgment values of the sensor amplifiers of the specified ID numbers are entered into judgment
value boxes 1 to 3.
If the judgment value is correct, the parameter range is
from - 99.999 to 99.999 (SK-050).
If the current value is over range, under range, or invalid, the previous value is retained without
updating the current value. Use the value with the judgment value property.
(6) When the "request to change judgment value page" command is set to 0, the "judgment value page
change complete" parameter flips to 0. If a judgment value page change error occurred, it is cleared (0).
(7) Once the judgment values of the sensor amplifiers are updated, the judgment value boxes are
updated by cyclic transfer.
Monitor mode 2/full mode
When reading judgment values (P.V. values) in monitor mode 2 or full mode, read the
remote registers assigned to the ID numbers of the sensor amplifiers. For details of
remote registers, see "Device Maps" (page 3-4).
When reading judgment values (P.V. values) in monitor mode 1, see "Monitor
mode 1" (page 3-19).
This example illustrates how to read the judgment values from the sensor amplifiers of ID 01, 02, and 03.
(1) When the judgment value of a sensor amplifier is updated, the new judgment value is entered into
remote register RWr.
If the judgment value is correct, the parameter range is
from - 99.999 to 99.999 (SK-050).
If the current value is over range, under range, or invalid, the previous value is retained without
updating the current value. Use the value with the judgment value property.
(2) If the judgment value of a sensor amplifier is "invalid," the bit corresponding to the ID number of that
sensor amplifier flips to 1.
(3) If the judgment value of a sensor amplifier is "over," the bit corresponding to the ID number of that
sensor amplifier flips to 1.
(4) If the judgment value of a sensor amplifier is "under," the bit corresponding to the ID number of that
sensor amplifier flips to 1.
