4 Data Exchange with the CPU Unit
4-12
CJ-series PROFINET IO Controller Unit Operation Manual for NJ-series CPU Unit (W511)
Name of device variable
for CJ-series Unit
Type
R/W
Area
Function
*_OnlineSta
BOOL
RO
Controller in
ONLINE mode
FALSE: Turned OFF by the Unit if it is currently
not in ONLINE mode.
TRUE: Turned ON by the Unit if it is currently in
ONLINE mode. In this case
*_OfflineSta
will be
OFF.
ONLINE means that the CJ1W-PNT21 is capa-
ble of communicating on the network.
The unit can not communicate on the network if
hardware errors occur during startup or normal
operation.
*_OfflineSta
BOOL
RO
Controller is in
OFFLINE
mode
FALSE: Turned OFF by the Unit if it is currently
not in OFFLINE mode.
TRUE: Turned ON by the Unit if it is currently in
ONLINE mode. In this case *_OnlineSta will be
turned OFF. OFFLINE means that the CJ1W-
PNT21 is currently not capable of communicat-
ing on the network. The unit cannot communi-
cate on the network if hardware errors occur
during startup or normal operation.
*_DatXchgSta
BOOL
RO
Controller in
Data
Exchange
mode
FALSE: Turned OFF by the Unit if none of the IO
Devices are providing valid input data to the Unit.
TRUE: Turned ON by the Unit if at least one of
the IO Devices is providing valid input data to the
Unit.
*_ValidCfgSta
BOOL
RO
Unit contains a
valid configu-
ration
FALSE: Turned OFF by the Unit if it has not been
configured correctly.
TRUE: Turned ON by the Unit if it is able to use
the internally stored configuration data indicating
the Unit contains valid PROFINET IO Configura-
tion data. With this configuration data the IO
Controller can parameterize the allocated IO
Devices and start exchanging I/O data.
*_OutDatValSta
BOOL
RO
Valid output
data
FALSE: Turned OFF by the Unit if the data sent
to the IO Devices is marked as invalid.
TRUE: Turned ON by the Unit if the data sent to
the IO Devices is marked as valid.
*_LinkSta
BOOL
RO
Link Status
FALSE: Turned OFF by the Unit if there is an
Ethernet cable connected to the port of the IO
Controller and a link was successfully created to
an IO Device, switch or other Ethernet device.
TRUE: Set ON by the Unit if there is no Ethernet
cable connected to the port of the IO Controller
or a link could not be successfully created to an
IO Device, switch or other Ethernet device. If the
unit cannot establish a link with another device at
100Mbps full-duplex then this bit will be set.
*_HwErr
BOOL
RO
Hardware
Error
FALSE: Turned OFF by the Unit of no hardware
errors have occurred.
TRUE: Turned ON by the Unit if hardware errors
have occurred on the bus, e.g. faults when
accessing the Ethernet controller or interrupted
data streams and broken messages.
*_CfgErr
BOOL
RO
Configuration
Error
FALSE: Turned OFF by the Unit if no Configura-
tion error has been detected.
TRUE: Turned ON by the Unit if one or more
Configuration errors have been detected in the
contents of the Configuration set.
