(27)CH Difference conversion status flag (Un\G190 to Un\G193)
Difference conversion status can be checked with this flag.
• When CH Difference conversion trigger (Un\G172 to Un\G175) is turned No request (0) → Requested (1),
CH Difference conversion status flag (Un\G190 to Un\G193) is turned to Converting difference (1).
• When CH Difference conversion trigger (Un\G172 to Un\G175) is turned Requested (1) → No request (0),
CH Difference conversion status flag (Un\G190 to Un\G193) is turned Converting difference (1)
→ Not
converted (0).
(28)Pass data classification setting (Un\G200)
This is the area for saving and restoring the offset/gain setting value in user range setting.
Specify if the offset/gain setting value to be saved or restored is either voltage or current.
(29)CH1 Industrial shipment settings offset value (L) (Un\G202) to CH4 User range
settings gain value (H) (Un\G233)
This is the area for restoring the offset/gain setting value in user range setting.
When the offset/gain setting of the user range setting is restored, the data to be used is stored with the following
operation.
• Writing the initial setting by utility
• Turning OFF → ON Operating condition setting request (Y9) *
1
• Turning OFF → ON User range write request (YA) (in offset/gain setting mode)
*1 The data is not saved when the setting value is written to Mode switching setting (Un\G158, Un\G159).
When restoring the offset/gain setting value in user range setting, set the data saved in this area to the same area
in the A/D converter module where the data is restored.
For the setting procedure of offset/gain values or saving and restoring offset/gain values, refer to the following.
• Offset/gain setting ( Page 54, Section 7.5)
• Saving and restoring offset/gain values ( Page 124, Section 8.19)
