Status Area and Troubleshooting
Terminating Resistance Status: CIO 1500 + 25
298
Bit status
Data link table error
(CIO 1500 + 25 n, bit 1)
is 1: ON
Network parameter error
(CIO 1500 + 25 n, bit 0)
is 1: ON
(Unit No.) + 24
Probable cause
The data link table data in
the CS/CJ CPU Bus Unit
Area is damaged.
There is an error in the
data link table settings.
The network parameter
data in the CS/CJ CPU
Bus Unit Area is damaged.
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.
Terminating resistance status:
Section 9-2
Probable remedy
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.
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.
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
Initialize network parame-
ters operation on the Main-
tenance Menu of the
Controller Link Support
Software to initialize the
network parameters and
then cycle the power sup-
ply.
Refer to 8-1-3 Network
Parameters and reset the
network parameters or the
node address.
