These bits operate automatically when executing
I/O READ/WRITE i
I/O READ/WRITE instructions.
This flag is turned ON when invalid data is received
from the I/O WRITE instruction, WRIT. 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.
OFF: Normal
ON: High-speed
---
---
This flag is turned ON when conversion data
exceeds the upper limit or drops below the lower
limit. It is cleared when conversion data between the
upper and lower limits is written.
This flag is turned ON when external power supply
is turned ON.
---
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 has been completed.
This flag is turned ON when the internal diagnostic
function ends normally. It is turned OFF when an
internal error has been detected. If turning the
power OFF and then ON does not turn OFF this
flag, replace the Unit.
