CX-ConfiguratorFDT provides several means to troubleshoot either the CJ1WPNT21 PROFINET IO
Controller Unit, the IO Devices or the network. The means all rely on features discussed in the pre-
vious section.
 Troubleshooting the IO Controller Unit
To troubleshoot the IO Controller Unit or the network, the IO Controller DTM Diagnosis User Inter-
face provides a help in determining problems. The figure below shows the Diagnosis for the IO Con-
troller Status item of the IO Controller DTM Diagnosis User Interface.
The indicators shown in the (example) figure above are all related to Device Variable flags in the
Unit Status, the IO Controller Status 1 and the IO Device Status areas.

Unit Status
The table below lists combinations of indicators with information on possible problems. They are
derived from the Unit Status. If one of the errors occur then there is a problem with the IO Controller
itself and the unit may need to be replaced.
7-2-2 Troubleshooting the Network using CX-ConfiguratorFDT
Indicators Description/Correction
Unit Error The Unit Error flag is TRUE if the unit has an error (if one of the other error flags in
the Unit Status is TRUE).
Controller Error The Controller Error Flag is TRUE if one of the IO Controller Status 2 error flags is
TRUE.
Error Log contains errors When a new error is logged in the Error Log then this flag is TRUE. After reading
or clearing the Error Log this flag is FALSE. Reading or Clearing the Error Log can
be done or by the Diagnosis Error History of the IO Controller DTM or by using the
appropriate message command.
Configuration Transfer in progress During download of a new configuration from the IO Controller DTM to the IO Con-
troller this flag is TRUE.
Local Configuration Storage Error After the download of a new configuration the IO Controller will store the configu-
ration in its memory. If it does not succeed then this flag is TRUE. Try to download
the configuration again. If the problem persists the replace the IO Controller.
Local Configuration Load Error During startup of the IO Controller loads the configuration from memory. If it does
not succeed then this flag is TRUE. Try to download the configuration again. If the
problem persists the replace the IO Controller.
