Troubleshooting Section 8-1
Note Calculate the location of the error information in the CPU Bus Unit as follows:
CIO 1500 + unit number x 25 + 1 word.
Lit --- Lit --- Bit 15 (error log infor-
mation) is ON. 0001
Hex CPU Unit error. Refer to the PLC operation
manual, and clear the error. If
the error reoccurs, replace
the CPU Unit.
Both bit 00 (network
parameter error) and
bit 15 (error log infor-
mation) are ON. 0012
Hex CPU Bus Unit set-
tings area network
parameters data is
corrupted. Correct the network parame-
ters. If the error reoccurs,
replace the PLC CPU Unit.
021A
Hex Network parameter
settings contain an
error, or the local
node address
exceeds the network
parameters maxi-
mum node address. Correct the network parame-
ters correctly.
Both bit 01 (data link
table error) and bit 15
(error log informa-
tion) are ON. 0012
Hex PLC Bus Unit system
settings area data link
tables data is cor-
rupted. Correct the data link tables. If
the error reoccurs, replace
the PLC CPU Unit.
021A
Hex The data link table
settings contain an
error. Correct the data link tables,
or delete the data link tables
if not using them.
Both bit 02 (routing
table error) and bit 15
(error log informa-
tion) are ON. 0012
Hex PLC parameter area
routing tables data is
corrupted. Reset the routing tables. If
the error reoccurs, replace
the PLC CPU Unit.
021A
Hex The routing table set-
tings contain an error. Correct the routing tables, or
delete the routing tables if
not using them.
Lit --- --- Not lit --- --- Terminating resistors
are not mounted cor-
rectly (coaxial only). Mount terminating resistors
on both end nodes of the
SYSMAC LINK network.
--- --- The cable is not con-
nected correctly. Connect the cable connec-
tions, then reconnect the
cable correctly.
--- --- Node address
exceeds network
parameters maxi-
mum node address. 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.
--- --- No other nodes exist. Be sure that there are a mini-
mum of two active nodes in
the network.
--- --- No node is set as the
polling node. Set a Unit as the polling
node.
