Error and Cause
"SP.UNIT
ERROR"
(Checked at
execution of the
FROM/TO
instruction or
the dedicated
instructions for
special function
modules.)
46 461 Stop or
Continue
(set by
parameter)
Module specified by the /
instruction is not a special function
module.
Read the error step using a peripheral
device and check and correct contents of
the
/ instruction of the step.
462 Module specified by the dedicated
instruction for special function module
is not a special function module or not a
corresponding special function module. Read the error step using a peripheral
device and check and correct contents of
the dedicated instruction for special
function modules of the step.
"LINK PARA.
ERROR"
47 — Continue (1) Data written to the parameter areas
of the link of which range was set by
parameters using a peripheral
device does not conform with the
data of link parameters read by the
CPU.
Or, link parameters are not written.
(2) Total number of local stations is set
at 0.
(1) Write in parameters again and check.
(2) Check setting of station numbers.
(3) If the same error indication is given
again, it is hardware failure.
Consult Mitsubishi representative.
"OPERATION
ERROR"
(Checked at
execution of
instruction.)
50 501 Stop or
Continue
(set by
parameter)
(1) When file registers (R) are used,
operation is executed outside of
specified ranges of device numbers
and block numbers of file registers
(R).
(2) File registers are used in the
program without setting capacity of
file registers.
Read the error step using a peripheral
device and check and correct program of
the step.
502 Combination of the devices specified by
instruction is incorrect.
503 Stored data or constant of specified
device is not in the usable range.
504 Set number of data to be handled is out
of the usable range.
505 (1) Station number specified by the
, ,
instructions is not a local
station.
(2) Head I/O number specified by the
, ,
instructions is not of a
remote station.
506 Head I/O number specified by the
, ,
instructions is not of a special
function module.
507 (1) When the AD57(S1) or AD58 was
executing instructions in divided
processing mode, other instructions
were executed to either of them.
(2) When an AD57(S1) or AD58 was
executing instructions in divided
processing mode, other instructions
were executed in divided mode to
another AD57(S1) or AD58.
Read the error step using a peripheral
device and provide interlock with special
relay M9066 or modify program structure
so that, when the AD57(S1) or AD58 is
executing instructions in divided
processing mode, other instructions may
not be executed to either of them or to
another AD57(S1) or AD58 in divided
mode.
