(9) Operation when Operating condition setting request (Y9) is turned OFF → ON
→ OFF
The following processing is performed by changing the settings in the following buffer memory areas and turning
Operating condition setting request (Y9) OFF → ON → OFF. The flow amount integration function is performed
with the changed settings.
Buffer memory
A/D conversion enable/disable setting
(Un\G0)
CH Time Average/ Count Average/Moving
Average (Un\G1 to Un\G4)
Averaging process setting (used to replace
Q64AD) (Un\G9)
Averaging process setting (Un\G24)
CH Integration cycle setting (Un\G1308 to
Un\G1311)
CH Flow amount time unit setting
(Un\G1316 to Un\G1319)
CH Unit scaling setting (Un\G1324 to
Un\G1327)
If Operating condition setting request (Y9) is turned OFF → ON → OFF and one of the following error occurs, the flow
amount integration function turns disabled.
• Setting error of CH

• Setting error of Conversion speed setting (Un\G26) (error code: 360 , error code: 210 )
• Setting error of CH
• Setting error of CH

• Integration cycles of all channels are changed just by changing 1 channel.
• The integral processing stops in the channel in which A/D conversion
enable/disable setting (Un\G0) changes from Enable (0) to Disable (0).
CH Integrated flow amount (Un\G1332 to Un\G1339) maintains the value
before changing.
• CH Integrated flow amount (Un\G1332 to Un\G1339) of the unchanged
channel is cleared to zero. After it is cleared, restart the integral processing
with the setting before turning on Operating condition setting request (Y9).
• The integration cycle changes in only the changed channel.
• CH Integrated flow amount (Un\G1332 to Un\G1339) of the changed
channel is cleared to zero.
• CH Integrated flow amount (Un\G1332 to Un\G1339) of the unchanged
channel is not cleared. The integral processing is continued with the
setting before turning on Operating condition setting request (Y9).
• Only in the changed channel, values to be stored in CH
amount (Un\G1332 to Un\G1339) are changed according to the changed
setting of the buffer memory.
• CH Integrated flow amount (Un\G1332 to Un\G1339) of the changed
channel is cleared to zero.
• CH Integrated flow amount (Un\G1332 to Un\G1339) of the unchanged
channel is not cleared. The integral processing is continued with the
setting before turning on Operating condition setting request (Y9).
