Overview
The PROFIBUS Communication Unit and the Configuration DTM provide
extensive means for troubleshooting, which can be used to quickly determine
errors in the Unit, in the SmartSlice I/O configuration, and/or in the network.
Troubleshooting on the
GRT1-PRT Unit
For troubleshooting purposes, the following error indicators can be used:
• LED indicators on the front of the Unit
Three red error LED indicators and four status LED indicators show Unit
and SmartSlice I/O system status and errors.
• The Error Log collects error codes for various error events. The Error Log
can be retrieved using the GRT1-PRT DTM.
• PROFIBUS errors
DP-V1 commands provide defined response codes, which can indicate
specific errors.
This section provides a number of procedures for troubleshooting, based on
the error indicators listed above.

Troubleshooting using the LED Indicators
The figure below shows the available LED indicators on the PROFIBUS Com-
munication Unit and on the SmartSlice I/O system attached to it. The GRT1-
PRT and the SmartSlice I/O Units are operating normally when all of the LED
indicators are lit green.
Note
Not shown in the figure above is a Turnback Unit. The Turnback Unit also pro-
vides I/O PWR, UNIT PWR and TS LED Indicators.
The LED indicators can be used to determine the following categories of
errors
• Power errors
• Startup errors
• SmartSlice I/O Unit errors
• PROFIBUS errors
RUN LED: Indicates the status of the PROFIBUS Communication Unit.
ERR LED: Indicates the status of PROFIBUS Communication Unit.
BF LED: Indicates the status of the PROFIBUS Communication
TS LED: Indicates the status of the SmartSlice I/O System.
UNIT PWR: Indicates the status of the Unit power supply.
I/O PWR: Indicates the status of the I/O power supply.
TS LEDs: Indicate the status of each SmartSlice I/O Unit.
