03:
Communications
controller error
01 Error occurred in the communications
controller, ERC indicator is lit.
Take corrective action, referring to
troubleshooting procedures in this section.
02 CPU Unit error occurred in the PC at the
remote node.
Check CPU Unit indicators at the remote node
and clear the error in the CPU Unit (refer to the
PC’s operation manuals)
04 Unit number setting error Make sure the unit number is within the
specified range and that the same unit number
is not used twice in the same network.
04: Not
executable
01
An undefined command has been used. Check the command code and be sure the
command is supported by the Unit to which
you are sending it.
(Service not
supported.)
A short frame (4 bytes) is being used for
the FINS header frame.
Check the FINS header frame length. The
Ethernet Unit does not support short headers.
05: Routing error 01 Remote node is not set in the routing
tables.
Set the destination address in the routing
tables.
02 Routing tables aren’t registered
completely.
Set routing tables at the local node, remote
node, and any relay nodes.
03 Routing table error Set the routing tables correctly.
04 The maximum number of relay nodes (2)
was exceeded in the command.
Redesign the network or reconsider the routing
table to reduce the number of relay nodes in
the command. Communications are possible
on three network levels, including the local
network.
10: Command
format error
01 The command is longer than the max.
permissible length.
Check the command format of the command
and set it correctly. Be sure broadcast
transmissions don’t exceed 1,473 bytes.
02 The command is shorter than min.
permissible length.
Check the command format of the command
and set it correctly.
03 The designated number of data items
differs from the actual number in the
command data.
Check the number of items and the data, and
make sure that they agree.
05
Data for another node on the same
network was received from the network.
Check the header parameters in the command
data and be sure the correct command format
An attempt was made to send response
data for a broadcast address.
is being used.
11: Parameter
error
00 The parameters in the command data are
incorrect.
The UDP/TCP socket number was not
within the proper range.
The local UDP port number might be set
to 0.
Check the parameters.
Be sure the socket number is between 1 and
8.
Set the Local UDP port number correctly.
01 A correct memory area code has not
been used or EM Area is not available.
Check the command’s memory area code in
the Results Storage Area and set the
appropriate code.
03 The first word is in an inaccessible area
or the bit number is not 00.
Set a first word that is in an accessible area.
The bit number must be 00 for Ethernet Units.
04 The address set in the command is not
correct.
Correct the address in the command data,
being sure that the start address plus the
number of words does not exceed accessible
memory.
0B The response frame is too long. Correct the number of data elements or other
parameters in the command data for which the
response is being returned.
0C Parameters are set incorrectly in the
command data.
Check the command data and correct any
parameters that are incorrect.
