Judgment values (P.V. values) can be read in the monitor modes and full modes.
They cannot be read in small-memory modes.
Monitor mode 1
When reading judgment values (P.V. values) in monitor mode 1, specify the ID
numbers (in terms of judgment value page numbers) of the sensor amplifiers to be
read to judgment value boxes 1 to 3. For details of the judgment value box numbers
and judgment value page numbers used for specifying ID numbers, see "Device
Maps" (page 3-4).
When reading judgment values in monitor mode 2 or full mode, see "Monitor
mode 2/full mode" (page 3-20).
This example illustrates how to read the judgment values (P.V. values) from the sensor amplifiers of ID
01/02/03 and ID 04.
(1) Specify the page numbers in "select judgment value box page number" and execute "request to
change judgment value page".
(2) After the judgment values of the specified judgment value pages are read, the "judgment value page
change complete" signal flips from 0 to 1.
(3) The "judgment value page change error" signal flips from 0 to 1 if an error occurs during the
judgment value change process. Check the values specified in the "select judgment value box page
number" parameter.
(4) The property of each judgment value is entered. Check that each judgment value is normal value,
"over," "under," or "invalid."
