Status Area
The Status Area indicates the operating status of the C200H I/O Link Unit.
The meaning of each bit is as shown in the following diagram.
Network Power Supply Error
Communications Error
Hold/Clear Write Area Data for Communications Error
Read/Write Area Settings Normal Completion
Read/Write Area Settings Error Completion
Explicit Connection Established
ON
Turns ON when an incorrect switch set-
ting or an error in EEPROM is detected.
Turns ON when the same node address
is set for more than one Unit or a Bus Off
(communications are halted by many
communications errors) error is detected.
Turns ON when a PLC mounting error is
detected. (When another Communica-
tions Unit is mounted to the same PLC
and it's Read/Write Area settings are set
to default.)
Turns ON when power OFF is detected in
the DeviceNet Network.
Turns ON when a DeviceNet communi-
cations error is detected.
Turns ON when the Unit is restarted after
pin 3 on the front panel DIP switch has
been set to ON (Hold).
Turns ON when changes to the Read/
Write Area settings have been completed
normally using software switch bit 0 or 1.
Turns ON when an error has occurred
attempting to make changes to the Read/
Write Area settings using software switch
bit 0 or 1.
Turns ON when an explicit connection
has been established with the Master
Unit.
Turns ON when Read/Write Area default
settings are used.
Turns ON when any kind of error occurs.
(When Status bits 00, 01, 02, 06, or 10
are ON.)
Turns ON when a connection is estab-
lished with the Master Unit.
Bit
Not used
Incorrect Switch Settings/EEPROM Error
Node Address Duplication/Bus Off Error Detected
PLC Mounting Error
Turns OFF when the PLC or C200H I/O
Link Unit is restarted.
Turns OFF when the PLC or C200H I/O
Link Unit is restarted.
Turns OFF when the Read/Write Area is
set to user settings and the C200H I/O
Link Unit is restarted.
Turns OFF when the communications
power supply returns to a normal volt-
age.
Turns OFF when communications return
to normal.
Turns OFF when the Unit is restarted
after pin 3 on the front panel DIP switch
has been set to OFF (Clear).
Turns OFF when software switch bits 0
and 1 are both set to OFF.
Turns OFF when software switch bits 0
and 1 are both set to OFF.
Turns OFF when the explicit connection
with the Master Unit is broken.
Turns OFF when Read/Write Area user
settings are used.
Turns OFF when all errors have been
resolved. (When Status bits 00, 01, 02,
06, and 10 are all OFF.)
Turns OFF when a connection with the
Master Unit is broken.
