Turns on when a self-diagnostic error occurs.
The self-diagnostic error code is stored in DT90000.
-
Turns on when a communication error occurs in the
MEWNET-TR master unit or MEWNET-TR network. The
slot, where the erroneous MEWNET-TR master unit is
installed, can be checked using DT90002 or DT90003.
Turns on when the error occurs in the I/O unit. The slot
number of the unit where the error was occurred is stored in
DT90002, DT90003.
Turns on when an error occurs in an intelligent unit. The slot
number, where the erroneous intelligent unit is installed is
stored in DT90006 or DT90007.
Turns on when an I/O verification error occurs.
The slot number of the I/O unit where the verification error
was occurred is stored in DT90010 or DT90011.
Turns on for an instant when a backup battery error occurs.
Turns on and keeps the on state when a backup battery
error occurs. To reset R9006,
- turn the power to off and then turn it on,
- initialize, after removing the cause of error.
Turns on and keeps the on state when an operation error
occurs. The address where the error occurred is stored in
DT90017.
(Indicates the first operation error which occurred).
FP2SH／FP10SH:
When program is 120k steps and the higher byte of
DT90257 is H2, the error occurs in the 2nd program block. In
case of the 1st program block, it is H1.
Turns on for an instant when an operation error occurs. The
address where the operation error occurred is stored in
DT90018
The contents change each time a new error occurs.
FP2SH／FP10SH:
When program is 120k steps and the higher byte of
DT90258 is H2, the error occurs in the 2nd program block. In
case of the 1st program block, it is H1.
Turns on for an instant,
- when an overflow or underflow occurs.
- when "1" is set by one of the shift instructions.
Turns on for an instant when the compared results become
larger in the "F60 (CMP)/P60 (PCMP),
F61(DCMP)P61(PDCMP),F62 (WIN)/P62 (PWIN) or F63
(DWIN)/P63 (PDWIN) comparison instructions."
Turns on for an instant,
when the compared results are equal in the comparison
-
instructions.
when the calculated results become 0 in the arithmetic
-
instructions.
