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-68DAVN 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-
68DAVN to request the initial data to be set.
Also, after the initial data processing is complete (initial data processing complete 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 setting complete flag turns off
when the initial data setting request flag turns off.
Turns on at occurrence of the output range setting error, digital value setting error or
