(5) The current values of the sensor amplifiers of the specified ID numbers are entered into current value
boxes 1 to 3.
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 current value page" command is set to 0, the "current value page
change complete" parameter flips to 0. If a current value page change error occurred, it is cleared
(0).
(7) Once the current values of the sensor amplifiers are updated, the current value boxes are updated by
cyclic transfer.
Monitor mode 2/full mode
When reading current 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
When reading current values in monitor mode 1, see
18)
This example illustrates how to read the current values from the sensor amplifiers of ID 01, 02, and 03.
(1) When the current value of a sensor amplifier is updated, the new comparator value is entered into
remote register RWr.
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 judgement value "invalid", "over", or "under".
(2) If the current value of a sensor amplifier is "invalid" (----), the bit corresponding to the ID number of
that sensor amplifier flips to 1.
(3) If the current value of a sensor amplifier is "over" (FFFF), the bit corresponding to the ID number of
that sensor amplifier flips to 1.
