Status Area and Troubleshooting

10-2-2 CVM1 and CV-series Controller Link Units

Status Area
Error Information: CIO 1500 + 25 x (Unit No.)
Polling Node Address, Startup Node Address: CIO 1500 + 25 x (Unit No.) + 1
254
Bit status
Network parameter error (CIO 1500 +
25 × n, bit 0) is 1: ON
The status of the Unit and Network is indicated in the following manner in the
PLC.
Polling node address
Each node address is displayed in 2-digit BCD.
Probable cause
The network parameter
data in the CPU Bus
Unit Area is damaged.
There is an error in the
network parameter set-
tings, or node address
of the local node is
larger then the maxi-
mum address set within
the network parame-
ters.
1: Network parameter error (in PLC's EEPROM)
1: Data link table error (in PLC's EEPROM)
1: Routing table error (in PLC's EEPROM)
1: PLC system setting error
1: EEPROM error
1: Duplicate node address setting error
1: Inconsistent network parameters
1: Communications controller send error
1: Error log exists
Startup node address
Section 10-2
Probable remedy
Refer to 9-1-3 Network
Parameters and reset
the data correctly. If the
error occurs again,
replace the CPU Unit.
Either set the EEPROM
Clear Bit in the DM
parameter area to ON,
or use the Initialize net-
work parameters opera-
tion on the
Maintenance Menu of
the Controller Link Sup-
port Software to initial-
ize the network
parameters and then
cycle the power supply.
Refer to 9-1-3 Network
Parameters and reset
the network parame-
ters or the node
address.
