5.1.2 Table of Special Internal Relays for FP0

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.

Name
Turns on when a self-diagnostic error occurs.
The self-diagnostic error code is stored in DT9000.
-
Turns on when an I/O verification error occurs.
The position number of the I/O where the verification error
was occurred is stored in DT9010.
-
Turns on and keeps the on state shen an operation error
occurs.
The address where the error occurred is stored in DT9017.
(Indicates the first operation error which occurred).
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.
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) to F63 (DWIN) comparison
instructions."
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.
Turns on for an instant when the compared results become
smaller in the "F60 (CMP) to F63 (DWIN) comparison
instructions.
Turns on when the set time elapses (set value reaches 0) in
the timing operation of the F137(STMR)/F183(DSTM)
auxiliary timer instruction.
It turns off when the trigger for auxiliary timer instruction
turns off.
This turns on when an error occurs during communication
with a programming tool.
Turns on when the scan time exceeds the time specified in
system register 34 during constant scan execution.
Always on.
Always off.
Turns on and off alternately at each scan.
