CJ-series PROFINET IO Controller Unit Operation Manual for NJ-series CPU Unit (W511)
 IO Controller Status 1
The IO Controller Status 1 word displays the state of the Unit. It shows if the IO Controller can go on
the network and communicate with the current configuration with the IO Devices.
 IO Controller Status 2
The IO Controller Status 2 word displays the state of the Unit’s network interface. It shows if the
Ethernet cable is correctly inserted in the IO Controller and an Ethernet Link could be established to
the connected switch or IO Device. Or that the Ethernet interface of the Unit itself encountered a
problem.
 IO Device Status
The IO Device Status word displays the state of the Unit’s communication to its assigned IO
Devices. Whether all or at least one IO Device that can process output data are connected. And if all
IO Devices configured are supplying valid input data.
If one or more IO Devices have an Alarm then this will also be signalled.
File Read Error If the IO Controller restores a configuration from Compact Flash card in the CPU
and it can not access the configuration file on the Compact Flash card then this
flag is TRUE.
*Limited memory card functionality based on CPU version. Check specification
details for more information.
Error Log Storage Error If a new error needs to be written to the Error Log and the IO Controller does not
succeed in storing this error in the Error Log then this flag is TRUE.
Indicators Description/Correction
Controller is ONLINE Normally the IO Controller is always Online. If the IO Controller has gone Offline
then a severe error has occurred. Check the Unit Status and the Error History to
see the cause. The IO Controller may need to be replaced.
Controller is in Data Exchange The IO Controller is in Data Exchange when it can reach at least one of the config-
ured IO Devices. This shows that the network connection to the IO Devices works.
If some of the IO Devices can not be reached it is a network issue and not an
issue of the IO Controller. If the IO Controller is out of Data Exchange it means
that their is something wrong with the network connection from the IO Controller to
the IO Devices.
Valid Configuration At startup the IO Controller checks if the stored configuration is valid. A new IO
Controller contains no configuration yet so therefore it will show it has no valid
configuration.
If a configuration is not valid it means that means the file could be damaged. It is
possible to download the configuration again with CX-ConfiguratorFDT.
If downloading the configuration to the Unit does not solve the issue then replace
the unit.
Indicators Description/Correction
Link Status The Unit could not establish an ethernet link at 100Mbps, Full Duplex to the con-
nected switch or IO Device. It could be that the Ethernet cable is damaged or not
correctly inserted. Or that the connected device has a fault.
Hardware Error The Ethernet controller of the Unit encountered a problem. It could be because of
faulty access or there where broken messages or interrupted data streams from
the network. This could be caused by external influences on the network.
Configuration Error At startup the IO Controller checks if the stored configuration is valid. A new IO
Controller contains no configuration yet so therefore it will show it has no valid
configuration.
If a configuration is not valid it could be that the file is damaged. It is possible to
download the configuration again with CX-ConfiguratorFDT.
If downloading the configuration to the Unit does not solve the issue then replace
the unit.
