4.7 Error Codes
Error details and cause
Online operation was interrupted due to a remote
head module error.
Request data error
The specified command cannot be executed
because it is being executed.
The remote request cannot be executed.
The specified label name does not exist.
Label access with a label name has failed because
the specified array element number is out of range.
Label access with a label name has failed because
the bit array type label is not specified by bit
specification.
Label access with a label name has failed because
the word array type label is not specified by word
specification.
Label access with a label name has failed because
the number of labels used in the program exceeded
its limit.
Registration of a label definition has failed because
the number of registered labels reached its limit.
A label definition could not be registered because
the registration target memory capacity has been
exceeded its limit.
A label definition could not be changed, added, or
deleted because the label communication data does
not exist in the remote head module.
Data are not written to the CPU module because the
data type of the specified label does not match the
size of the write data.
Online program change has failed because the
global setting file before modification and the global
label assignment information do not match.
An attempt was made to access a label that cannot
be accessed with a label name.
Hardware failure of the remote head module.
The device monitor/test cannot be performed
normally.
Writing to the specified data is not supported.
The request cannot be executed because a
moderate or major error has occurred in the remote
head module.
The specified drive (memory) or file does not exist.
The specified drive (memory) or file does not exist.
Action
Check the status of the remote head module by
executing the module diagnostics.
Identify the error, and take a corrective action
referring to the troubleshooting section.
Check the request data that has been specified.
Execute the command again after the processing of
the command from another engineering tool ends.
• Change the status of the remote head module so
that the remote request can be executed, and
execute the request again.
• For remote operation, set the parameter to
"Enable remote reset".
Check the label setting. If the "Access from External
Device" checkbox is not selected, check the
checkbox.
Specify the array element number within the set
range.
Specify the label by bit specification, and access
again.
Specify the label by word specification, and access
again.
Reduce the number of labels in the program, and
access the labels multiple times.
Reduce the number of registered labels with the
"Access from External Device" checkbox selected.
• Reduce the number of registered labels with the
"Access from External Device" checkbox selected.
• Change the settings of the functions that use the
registration target memory.
Write the label communication data to the
programmable controller.
Change the size of data written from the external
device (SLMP/MC protocol device) so that it
matches the data type of the label in the specified
remote head module.
Write the global setting file and the global label
assignment information to the programmable
controller together after modification.
• Change the data type of the specified label to the
one other than "Function Block" or "Pointer".
• Change the class of the specified label to the one
other than "VAR_GLOBAL_CONSTANT".
• Specify a device that is not being modified. (Bit-
specified word devices and digit-specified bit
devices can be specified.)
Replace the remote head module.
Execute the function again. Check that the access
prohibited area is not accessed, and execute the
function again.
• Check that the version of the engineering tool
used is correct.
• Check the settings and make a correction.
Reset the remote head module, and execute the
request again.
Execute again after checking the specified drive
(memory) or file.
Execute again after checking the specified drive
(memory) or file.
