Check point
Error occurred in the communi-
cations controller, ERC indica-
tor is lit.
CPU Unit error occurred in the
PLC at the remote node.
Unit number setting error
An undefined command has
been used.
A short frame (4 bytes) is being
used for the FINS header
frame.
Remote node is not set in the
routing tables.
Routing tables aren’t registered
completely.
Routing table error
The maximum number of relay
nodes (2) was exceeded in the
command.
The command is longer than
the max. permissible length.
The command is shorter than
min. permissible length.
The designated number of data
items differs from the actual
number in the command data.
Data for another node on the
same network was received
from the network.
An attempt was made to send
response data for a broadcast
address.
Probable cause
Take corrective action, referring
to troubleshooting procedures in
this section.
Check CPU Unit indicators at the
remote node and clear the error
in the CPU Unit (refer to the PC’s
operation manuals)
Make sure the unit number is
within the specified range and
that the same unit number is not
used twice in the same network.
Check the command code and
be sure the command is sup-
ported by the Unit to which you
are sending it.
Check the FINS header frame
length. The Ethernet Unit does
not support short headers.
Set the destination address in
the routing tables.
Set routing tables at the local
node, remote node, and any
relay nodes.
Set the routing tables correctly.
Redesign the network or recon-
sider the routing table to reduce
the number of relay nodes in the
command. Communications are
possible on three network levels,
including the local network.
Check the command format of
the command and set it correctly.
Be sure broadcast transmissions
don’t exceed 1,473 bytes.
Check the command format of
the command and set it correctly.
Check the number of items and
the data, and make sure that
they agree.
Check the header parameters in
the command data and be sure
the correct command format is
being used.
