Current values can be read in the monitor modes and full modes. They cannot be
read in small-memory modes. Instantaneous flow rate is read as the current value
regardless of the detection mode setting.
Monitor mode 1
When reading current values in monitor mode 1, specify the ID numbers (in terms of
current value page numbers) of the sensor amplifiers to be read to current value
boxes 1 to 3. For details of the current value box numbers and current value page
numbers used for specifying ID numbers, see "Device Maps" (page 3-4).
When reading current values in monitor mode 2 or full mode, see "Monitor mode
2/full mode" (page 3-19).
This example illustrates how to read the current values from the sensor amplifiers of ID 01/02/03 and ID
07/08/09.
(1) Specify the page numbers in "select current value box page number" and execute "request to change
current value page".
(2) After the current values of the specified current value pages are read, the "current value page
change complete" signal flips from 0 to 1.
(3) The "current value page change error" signal flips from 0 to 1 if an error occurs during the current
value change process. Check the values specified in the "select current value box page number"
parameter.
(4) The property of each current value is entered. Check that each current value is normal value, "over"
(FFFF), or "invalid" (----).
