Name
This data is automatically read from RAM
addresses specified by the Read/Write Pointer (bits
08 to 15 of word n+1) when a read cycle is
performed for the Analog Output Unit.

This flag is turned ON when invalid data is sent to
the Analog Output Unit. The Analog Output Unit will
return to the original configuration and ignore all
data containing errors. This flag is turned OFF when
valid data is written.
This flag is turned ON when a conversion error is
detected in the Analog Output Unit. The Analog
Output Unit will return to the original configuration
and ignore all data containing errors. This flag is
turned OFF when valid data is written.
This flag is used to select either of the following
conversion speed modes.
ON: Normal
OFF: High-speed
This flag is turned ON when the Analog Output Unit
reads data from words n and n+1. The Analog
Output Unit uses this flag to notify the CPU Unit that
data has been read from words n and n+1.
This flag is turned ON when the Analog Output Unit
writes data to word n+2. The Analog Output Unit
uses this flag to notify the CPU Unit that data has
been written to word n+2.
This flag is turned ON when conversion data
exceeds the upper limit or drops below the lower
limit. It is turned OFF when conversion data
between the upper and lower limits is written.
This flag is turned ON when external power supply
is turned ON.
This flag indicates a transfer protocol error. It is
turned ON when the data transfer sequence ends
abnormally. This flag is turned OFF by setting or
resetting the PC Read Completed Bit (bit 07 of word
n+1). All read and write operations are ignored until
this flag is turned OFF.
The Analog Output Unit generates ON-OFF signals
with a frequency of 1 Hz and a load cycle of 50%
(ON for 0.5 second, OFF for 0.5 second) during
normal operation. It temporarily stops outputting
pulse signals while data is being written to
EEPROM, and restarts outputting signals when the
write operation is completed.
This flag is turned ON when the internal diagnostic
function ends normally. It is turned OFF when an
internal error is detected. If turning the power OFF
and then ON does not turn OFF this flag, replace
the Unit.
