Error description
code
• The connected device specified a wrong
56
H
device.
• The number of points for a command
specified by a connected device exceeds
the maximum number of processing
points (number of processes that can be
executed per communication) for each
process.
• Addresses from the start address (start
device number and start step number) to
the specified number of points exceed the
largest addresses (device number and
step number) for each process.
• The byte length of a command is not
within the range defined by the
specifications.
57
• When data is written, the set number of
H
write data points is different from the
specified number of points.
• A monitor request was issued even
though monitoring data is not registered.
• For data read/write in a microcomputer
program, an address after the last
address that can be set in the parameter
setting has been specified.
• In the block number specification of the
extension file register, a block number
exceeding the range of the corresponding
memory cassette size has been specified.
• The start address (start device number
and start step number) of a command
specified by a connected device has been
set outside the range that can be
specified.
• For data read/write in a microcomputer
program or file register, values exceeding
the CPU module parameter setting range
has been specified.
• A block number specified for an extension
58
H
file register does not exist.
• A file register cannot be specified.
• A word device has been specified for the
command for bit devices.
• The start number of bit devices has been
specified using a value other than a
multiple of 16 in the command for word
devices.
• An extension file register cannot be

• Correct the device
specification.
• Correct the specified points
or the start address (device
number and step number).
• Check the data length of the
command and set the data
again.
• Register the monitoring
data.
• Data cannot be read
from/written to an area with
an address after the last
address. Correct the
specified address.
• Correct the block number.
• Correct the value to the one
within the range that can be
specified for each process.
• Correct the block number.
• Correct the device
specification.
• Correct the command or
specified device.
• Correct the device
specification.
• Check the error code
appended to the end code
and correct the error.
• Increase the CPU
monitoring timer value.
