CQM1H-series Controller Link Units

Status Area
Error Information: IR 190
Polling Node Address, Startup Node Address: IR 191
Network Participation Status: IR 192 and IR 193
306
Bit status
Network parameter error
(CIO 1500 + 25 × n, bit 0)
is 1: ON
Polling node address
Each node address is displayed in 2-digit BCD.
IR 192
IR 193
The numbers in the squares indicate node addresses.
The corresponding node participation status is as follows:
0: Not part of the network
1: Part of the network
Probable cause
The CPU Unit's EEPROM
data link tables or the net-
work parameters are cor-
rupted.
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.
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 9-2
Probable remedy
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.
