Remedy
Refer to the PLC operation
manual, and clear the error. If
the error reoccurs, replace
the CPU Unit.
Correct the network parame-
ters. If the error reoccurs,
replace the PLC CPU Unit.
Correct the network parame-
ters correctly.
Correct the data link tables. If
the error reoccurs, replace
the PLC CPU Unit.
Correct the data link tables,
or delete the data link tables
if not using them.
Reset the routing tables. If
the error reoccurs, replace
the PLC CPU Unit.
Correct the routing tables, or
delete the routing tables if
not using them.
Mount terminating resistors
on both end nodes of the
SYSMAC LINK network.
Connect the cable connec-
tions, then reconnect the
cable correctly.
Either correct the network
parameters maximum node
address using CX-Net in CX-
Programmer, or set the node
address to within the maxi-
mum node address.
mum of two active nodes in
the network.
Set a Unit as the polling
node.
