Name
Description
R9000
Self-diagnostic
error flag
Turns on when a self-diagnostic error occurs.
⇒
The content of self-diagnostic error is stored in DT90000.
R9001
Not used
R9002
Not used
R9003
Not used
R9004
I/O verification
error flag
Turns on when an I/O verification error occurs.
R9005
Not used
R9006
Not used
R9007
Operation error
flag (hold)
Turns on and keeps the on state shen an operation error occurs.
⇒
The address where the error occurred is stored in DT90017.
(indicates the first operation error which occurred).
R9008
Operation error
flag (non-hold)
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.
R9009
Carry flag
This is set if an overflow or underflow occurs in the calculation
results, and as a result of a shift system instruction being executed.
R900A
> Flag
Turns on for an instant when the compared results become larger
in the comparison instructions (F60 to F63).
R900B
= Flag
Turns on for an instant,
-
when the compared results are equal in the comparison
instructions (F60 to F63).
-
when the calculated results become 0 in the arithmetic
instructions.
R900C
< Flag
Turns on for an instant when the compared results become smaller
in the comparison instructions (F60 to F63).
R900D
Auxiliary timer
instruction flag
Turns on when the set time elapses (set value reaches 0) in the
timing operation of the F137(STMR)/F183(DSTM) auxiliary timer
instruction. The flag turns off when the trigger for auxiliary timer
instruction turns off.
R900E
Tool port
communication
error
Turns on when communication error at tool port is occurred.
R900F
Constant scan
error flag
Turns on when scan time exceeds the time specified in system
register 34 during constant scan execution.
This goes on if 0 has been set using system register 34.
