Status Area and Troubleshooting Section 10-2
10-2-2 CVM1 and CV-series Controller Link Units
The status of the Unit and Network is indicated in the following manner in the
PLC.
Status Area
Error Information: CIO 1500 + 25 x (Unit No.)
Polling Node Address, Startup Node Address: CIO 1500 + 25 x (Unit No.) + 1
Network parameter error (CIO 1500 +
25
×
n, bit 0) is 1: ON
The network parameter
data in the CPU Bus
Unit Area is damaged. 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.
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. Refer to 9-1-3 Network
Parameters and reset
the network parame-
ters or the node
address.
