Overview
The CS1/CJ1W-PRM21 PROFIBUS Master Unit and the Configuration soft-
ware package provides extensive means for troubleshooting, which can be
used to quickly determine errors in the Unit, in the configuration, in the net-
work, and/or in remote slave devices, allocated to the Unit. For troubleshoot-
ing the Master units, refer to the CS1/CJ1W-PRM21 PROFIBUS Master Units
Operation Manual (W409-E2-
@
).
Troubleshooting the
Configuration Software
The Configuration software, i.e. CX-Profibus, the PROFIBUS Master DTMs
and the Generic Slave DTM provide several mechanisms for error detection
and correction:
• Errors occurring in CX-Profibus are displayed in pop-up message win-
dows and/or the error log window. The contents of the error log window
can be copied to the clipboard to allow analysis afterwards.
• CX-Profibus provides a FDT communication log window, which can be
copied to the clipboard. Analysis of this communication may provide addi-
tional information in case errors occur.
Troubleshooting the
network
The PROFIBUS Master DTM and the Generic Slave DTM diagnostics infor-
mation windows, which can display:
• Indications of errors in the PROFIBUS interface of the Unit
• Indications of errors in the communication between the PROFIBUS Mas-
ter Unit and remote slave devices.
• Indications of errors in the remote slave devices, allocated to the PROFI-
BUS Master Unit.
The CX-Profibus and DTM capabilities for troubleshooting are extensively dis-
cussed in
