3.4.15 Industrial shipment settings and user range settings offset/gain values
(buffer memory addresses 202 to 233: Un\G202 to Un\G233)
(1) Areas used to restore the user range settings offset/gain values when online
module change is made.
Refer to chapter 7 for details of online module change.
(2) When the offset/gain values of the user range setting are restored, the used data
are stored.
The data are stored (saved) when:
• Initial setting write is performed by the utility;
• The operating condition is set (Y9 turns from OFF to ON
1); or
• The offset/gain values are written in the offset/gain setting mode (YA turns from
OFF to ON).
1: The data are not saved when values have been written to the mode
switching setting area (buffer memory addresses 158, 159: Un\G158,
Un\G159).
(3) When restoring the offset/gain values of the user range setting, set the data
saved here similarly into the corresponding area of the module where the data
will be restored.
(4) Buffer memory saving recording procedure for online module change
1) Set the pass data classification setting
(buffer memory addresses 200:
Un\G200).
2) Turn the operation condition setting request (Y9) from OFF to ON.
3) Compare the offset/gain values of the industrial shipment settings and user
range settings (buffer memory addresses 202 to 233: Un\G202 to Un\G233)
with the range reference values. Refer to Section 7.4 for the range reference
values.
4) If the values are proper, record the offset/gain values of the pass data
classification setting
, industrial shipment settings and user range settings.
: The Q68ADV/Q68ADI does not require the setting and recording of the
pass data classification setting.
POINT
Refer to Section 4.6 for the offset/gain value setting method.
