SPECIFICATIONS
3.4.29 Factory default offset/gain values, User range settings offset/gain
values (Un\G190 to Un\G253)
This area is used to reset the offset/gain easily at online module change. (Refer to
CHAPTER 7)
(1) Purpose of this buffer memory
(a) When the offset/gain setting values of the user range setting are restored, the
data to be used are stored.
The data are stored (saved) in the following cases.
• When writing default setting by the utility
• When setting the operating condition (Y9 turns from off to on
*1
)
• When writing the offset/gain values in the offset/gain setting mode (YA turns
from off to on)
* 1 The data are not saved when a setting value has been written in the Mode switching setting
(Un\G158,Un\G159).
(b) To restore the offset/gain values of the user range setting, set the data saved in
this area to the corresponding area of the restoring target module.
(2) How to save data during online module change
Save buffer memory data during online module change in the following procedure.
1) Turn on Operating condition setting request (Y9).
2) Compare the values of the Factory default offset/gain values, the User range
settings offset/gain values, and the User range settings resistance offset/gain
values (Un\G190 to Un\G253) to the values in the range reference table.
(Refer to Section 7.4)
3) When the values are appropriate, take down the buffer memory data
compared.
