Overview
Note
The CJ1W-PNT21 PROFINET IO Controller Unit and the Configuration
software package provides extensive means for troubleshooting, which can be
used to quickly determine errors in the Unit, in the configuration, in the
network, and/or in IO Devices, allocated to the Unit.
For troubleshooting purposes, the following error indicators can be used:
•
•
•
•
•
n = CIO 1500 + (25 x unit number)
This section provides a number of procedures for troubleshooting, based on
the error indicators listed above.
The Configuration software, i.e. CX-ConfiguatorFDT, the PROFINET IO
Controller DTM and the Generic IO Device DTM provide several mechanisms
for error detection and correction:
•
•
The PROFINET IO Controller DTM and the Generic IO Device DTM provide
diagnostics information windows, which can display:
•
•
•
LED indicators on the front of the Unit
Two red/green and two yellow status LED indicators to show the Unit’s and
PROFINET IO network status and errors.
PROFINET IO errors
The PROFINET IO Configurator or DTMs can be used to find detailed
information about the errors on the PROFINET IO network.
CIO Words
Unit Status (CIO Word n + 4) containing status and error flags of the Unit,
and IO Controller Status 1 and 2 (CIO Word n+5 and n+6) containing error
information about the PROFINEt IO network and the PROFINET IO
functions of the Unit.
The Error Log collects error codes for various error events. Serious errors
are stored in non-volatile memory and can be retrieved, even after a Unit
power down.
FINS command provide defined response codes, which can indicate
specific errors.
Errors occurring in CX-ConfiguratorFDT are displayed in pop-up message
windows and/or the error log window. The contents of the error log window
can be copied to the clipboard to allow analysis afterwards.
CX-ConfiguratorFDT provides a FDT communication log window, which
can be copied to the clipboard. Analysis of this communication may provide
additional information in case errors occur.
Indications of errors in the PROFINET IO interface of the Unit
Indications of errors in the communication between the PROFINET IO
Controller Unit and IO Devices.
Indications of errors in the IO Devices, allocated to the PROFINET IO
Master Unit.
