The A/D conversion completion flag turns on at completion of the A/D conversion of the
corresponding channel when the initial data setting request flag (RY(n+1)9) turns from
off to on after power-on.
The A/D conversion completion flag processing is processed only once when the A/D
conversion enable/prohibit specification is changed.
When changing the A/D conversion from prohibit to enable:
When the average processing is specified, the flag turns on after completing the
average processing of the number of times or time, and storing the A/D conversion
digital value in the remote register.
When changing the A/D conversion from enable to prohibit:
The corresponding channel's A/D conversion completion flag turns off.
Turns on if the number of E
channel). If this flag has turned on, this module itself has failed (hardware fault) and
therefore this flag cannot be reset (turned off) by the error reset request flag.
At occurrence of this error, power on the AJ65VBTCU-68ADVN/ADIN again. If this flag
turns on after the power is switched on again, it is a hardware fault. Contact your
nearest Mitsubishi representative.
After power-on, the initial data processing request flag is turned on by the AJ65VBTCU-
68ADVN/ADIN to request the initial data to be set.
Also, after the initial data processing is complete (initial data processing completion flag
RY(n+1)8 ON), the flag is turned off.

When the initial data setting request (RY(n+1)9 ON) is made, the flag turns on after the
initial data setting completion is done.
Also, after the initial data setting is complete, the initial data setting completion flag
turns off when the initial data setting request flag turns off.
