State
Meaning
Power not supplied
The power is not supplied.
The I/O communications is active. (It can have explicit messaging as

Green
I/O communications
The communications has been started, but the I/O communications
stops. (Can have explicit messaging.) The state is achieved when the
Slave Unit participation is prioritized to the I/O communications at the
communications startup or when the user application explicitly requests
an idle state.

Error
Possible cause
Hardware error
One of the following occurs
•
Self-diagnosis at power-on
had a hardware error.
•
A Board WDT error occurs.
Board operation after error
detection
CompoNet Master Board
stops operation and is in
standby.
Action to be taken
If the same error persists
even it is connected to
other PC, replace the
CompoNet Master Board.
PC Watchdog
Timer error
PC WDT function detects
a PC WDT error.
(PC application stops.)
CompoNet Master Board
stops communications.
Restart the PC application
or the PC itself.
EEPROM error
Reading EEPROM failed.
Board starts up with all data
of Identity Objects in 0.
Replace the CompoNet
Master Board.
Network error
One of the following occurs
•
Duplication error on Slave
Units,
•
Slave Unit has an failure
stop due to unstable
communications.
All system operations
continue.
Identify which error it is
among the StateStatus of
the Basic status group.
Communications
error
One of the following occurs
•
Communications error on
Slave Unit,
•
Configuration error on
Repeater Unit,
•
Registration comparison
error,
•
Communications stop due
to communications error
All system operations
continue.
Communications stops only
when a communications
stop due to communications
error occurs.
Identify which error it is
