7 ONLINE MODULE CHANGE
7.3.6 When user range setting is used and initial setting was made with sequence program
(other system is unavailable)
(1) Conversion disable
(a) Set the A/D conversion enable/disable setting (buffer memory address 0:
Un\G0) for all channel conversion disable and turn Operation Condition
Setting Request (Y9) from OFF to ON to stop conversion.
(b) If the saved buffer memory contents are not yet prerecorded, record them
in the following procedure.
1) Make the pass data classification setting
(buffer memory address
200: Un\G200).
2) Turn Operation Condition Setting Request (Y9) from OFF to ON.
3) Compare the offset/gain values of the industrial shipment settings and
user range settings (buffer memory addresses 202 to 233: Un\G202 to
Un\G233) with the range reference table. Refer to Section 7.4 for the
range reference table.
4) If the values are proper, record the offset/gain values of the pass data
classification setting
, industrial shipment settings and user range
settings.
: The Q68ADV/Q68ADI does not require the setting and recording of the
pass data classification setting.
POINT
If the buffer memory values compared with the reference table are not proper, save
and restoration of the user range cannot be executed.
Before executing module control resumption, follow the flowchart in Section 4.6 and
make offset/gain setting in the device test of GX Developer.
Perform mode switching by making the setting of the mode switching setting (buffer
memory addresses 158, 159: Un\G158, Un\G159) and turning Operation Condition
Setting Request (Y9) from OFF to ON.
Note that if module control is resumed without offset/gain setting being made,
operation will be performed with the default values.
