3.4.19 Industrial shipment settings and user range settings offset/gain
values (Un\G202 to Un\G225)
(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 data to be
used are stored (saved) when:
• Initial setting is written by the utility;
• The operating condition is set (Y9 turns from off to on
*1
);
• 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 the set values have been written to Mode switch setting (Un\G158,
Un\G159).
(3) When restoring the offset/gain values of the user range setting, set the data saved in
this area similarly into the corresponding area of the module where the data will be
restored.
(4) Buffer memory saving record procedure for online module change
1) Set Pass data classification setting (Un\G200).
2) Turn Operating condition setting request (Y9) from off to on.
3) Compare the offset/gain values of CH Industrial shipment and User range
settings (Un\G202 to Un\G217) with the range reference table. Refer to Sec-
tion 7.4 for the range reference table.
4) If the values are proper, record the data in Pass data classification setting,
Industrial shipment settings, and User range settings.
Refer to Section 4.6 for the offset/gain value setting method.
