B.1 Special Internal Relays
The special internal relays turn on and off under special conditions. The on and off
states are not output externally. Writing is not possible with a programming tool or an
instruction.
Address Name Description
R9000 Self–diagnostic
error flag
Turns on when a self–diagnostic error occurs.
The self–diagnostic error code is stored in DT9000.
R9001 to
R9003
Not used
R9004 I/O verification error
flag
Turns on when an I/O verification error occurs.
The position number of the I/O where the verification error was occured is
stored in DT9010.
R9005,
R9006
Not used
R9007 Operation error flag
(hold)
Turns on and keeps the on state when an operation error occurs. The address
where the error occurred is stored in DT9017 (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 DT9018. The
contents change each time a new error occurs.
R9009 Carry flag Turns on for an instant,
– when an overflow or underflow occurs.
– when “1” is set by one of the shift instructions.
R900A > flag Turns on for an instant when the compared results become larger in the “F60
(CMP) to F63 (DWIN) comparison instructions.”
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 “F60
(CMP) to F63 (DWIN) comparison instructions.”
R900D Auxiliary timer
contact
Turns on when the set time elapses (set value reaches 0) in the timing opera-
tion of the F137 (STMR)/F183 (DSTM) auxiliary timer instruction.
It turns off when the trigger for auxiliary timer instruction turns off.
R900E Tool port error flag This turns on when an error occurs during communication with a programming
tool.
R900F Constant scan error
flag
Turns on when scan time exceeds the time specified in system register 34
during constant scan execution.
R9010 Always on relay Always on.
R9011 Always off relay Always off.
R9012 Scan pulse relay Turns on and off alternately at each scan.
R9013 Initial on pulse relay Turns on only at the first scan in the operation.
Turns off from the second scan and maintains the off state.
R9014 Initial off pulse relay Turns off only at the first scan in the operation.
Turns on from the second scan and maintains the on state.
R9015 Step ladder initial
on pulse relay
Turns on for an instant only in the first scan of the
process the moment step ladder process is opened.
