9-2-2 C200HX/HG/HE Controller Link Units
The status of the Unit and Network is indicated in the following manner in the
PC.
Data link table error
(CIO 1500 + 25
×
n, bit 1)
is 1: ON
The data link table data in
the CS/CJ CPU Bus Unit
Area is damaged. Refer to 5-3 Starting and
Stopping Data Links and
reset the data link tables
correctly. If the error occurs
again, replace the CPU
Unit.
There is an error in the
data link table settings. When using manually set
data links, refer to 5-3
Starting and Stopping Data
Links and remake and set
the data link tables cor-
rectly. When manually set
data links are not being
used, delete the data link
tables.
Network parameter error
(CIO 1500 + 25
×
n, bit 0)
is 1: ON
The network parameter
data in the CS/CJ CPU
Bus Unit Area is damaged. Refer to 8-1-3 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 param-
eter area to ON, or use the

tenance Menu of the
Controller Link Support
Software to initialize the
network parameters and
then cycle the power sup-

There is an error in the net-
work parameter settings, or
node address of the local
node is larger then the
maximum address set
within the network parame-
ters. Refer to 8-1-3 Network
Parameters and reset the
network parameters or the
node address.
