Function
The corresponding flag will be ON
when the settings for that port are being
changed.
The flag will be turned ON when
STUP(237) is executed and it will be
turned OFF by an event issued from the
Serial Communications Board after the
settings have been changed.
It is also possible for the user to indi-
cate a change in serial port settings by
turning these flags ON.
(Single CPU Systems only)
• Normal End (i.e., when A65014 is
OFF)
01 hex: Program file (.OBJ) replaced.
• Error End (i.e., when A65014 is ON)
00 hex: Fatal error
01 hex: Memory error
11 hex: Write-protected
12 hex: Program replacement pass-
word error
21 hex: No Memory Card
22 hex: No such file
23 hex: Specified file exceeds capac-
ity (memory error).
31 hex: One of the following in
progress:
• File memory operation
• User program write
• Operating mode change
ON when the Replacement Start Bit
(A65015) is turned ON to replace the
program, but there is an error. If the
Replacement Start Bit is turned ON
again, the Replacement Error Flag will
be turned OFF.
Program replacement starts when the
Replacement Start Bit is turned ON if
the Program Password (A651) is valid
(A5A5 hex). Do not turn OFF the
Replacement Start Bit during program
replacement.
When the power is turned ON or pro-
gram replacement is completed, the
Replacement Start Bit will be turned
OFF, regardless of whether replace-
ment was completed normally or in
error.
It is possible to confirm if program
replacement is being executed by read-
ing the Replacement Start Bit using a
Programming Device, PT, or host com-
puter.
