(1) This area is related with the user range save/restore function and allows users to
re-set the offset/gain values easily in the case 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 is written 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 set 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 into the corresponding area of the module where the data will be restored.
(4) In the Q64RD, two areas are provided for each of the factory default offset/gain
value/User range settings offset/gain value. (For example, the buffer memory
addresses for the 3-wire type CH1 Factory default offset value are 160 and 161.)
When saving the offset/gain values for Online Module Change, the same value is
stored into these two areas.
When restoring the offset/gain values, be sure to set the same value to both of
them.
In the Q64RD-G, one data value for each of the factory default offset/gain
value/User range settings offset/gain value is split into two (the first and second
halves) and stored separately. (For example, the buffer memory addresses for
the 3-wire type CH1 Factory default offset value are 160 and 161.)
When saving the offset/gain values for Online Module Change, the first and
second halves of one data value are stored into two areas.
When restoring the offset/gain values, be sure to set the first and second halves of
one data value to each of the areas.
(5) Buffer memory saving recording procedure for online module change
1) Turn the Operating condition setting request (Y9) from OFF to ON.
2) Compare the factory default offset/gain value/user range settings offset/gain
value/user range settings offset/gain resistance value (buffer memory
addresses 160 to 255: Un\G160 to Un\G255) with the values in the range
reference table. Refer to Section 7.4 for the range reference table.
3) If the values are proper, record the factory default offset/gain value/user range
settings offset/gain input value/user range settings offset/gain resistance value.
(6) Refer to Chapter 7 for details of online module change.
POINT
This area is not used for the offset/gain setting.
For the offset/gain setting, refer to Section 4.6.
