(1) Set the values of the mode to which you want to switch.
(2) After setting the values, turning the operation condition setting request (Y9) from
OFF to ON switches to that mode.
(3) When mode switching is performed, this area is cleared to zero and the operating
condition setting completed flag (X9) turns OFF.
After confirming that the operating condition setting completed flag (X9) has
turned OFF, turn OFF the operation condition setting request (Y9).
Mode to be switched to
Normal mode
Offset/gain setting mode
POINT
If the values written are other than the above, mode switching is not performed and
only the operating condition is changed.
(1) When the offset/gain values of the user 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 set values have been written to the mode
switching setting area (buffer memory addresses 158, 159: Un\G158,
Un\G159).
(2) When restoring the offset/gain values of the user setting, set the data saved here
similarly into the corresponding area of the module where the data will be restored.
(3) There are two areas of the same value for each of the factory setting/user setting
offset/gain input values. (Example: The areas for the 3-wire type CH. 1 factory
setting offset input value are buffer memory addresses 160 and 161.)
When the offset/gain value is saved, the same value is stored into both areas.
When restoring the offset/gain set value, always set the same value in both areas.
(4) Buffer memory saving recording procedure for online module change
1) Turn the operation condition setting request (Y9) from OFF to ON.
2) Compare the offset/gain values of the factory setting and user range setting
(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 offset/gain values of the factory setting and
user range setting.
(5) Refer to Chapter 7 for details of online module change.
