Status Area
Error Information: IR 190
Data link table error
(CIO 1500 + 25
×
n, bit 1)
is 1: ON
The data link table data in
the EEPROM of the CPU
Unit 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 CPU Unit’s EEPROM
data link tables or the net-
work parameters are dam-
aged. 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.
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.
