Overview
The Gateway has several useful LED indicators. These indicators can be
used for troubleshooting and checking the operation.
These LED indicators are:
• RUN, indicates normal operation.
• ERR, fatal error.
• FCOM, Host Link / Compoway-F communication.
• FERR, communication error with Host Link or Compoway-F.
• COMM, communication with PROFIBUS master.
• BF, all communication with the PROFIBUS master has lost or configura-
tion/parameter error occurs.

Troubleshooting Using LED Indicators
As mentioned before the LED indicators are very useful to get a correct diag-
nosis of the Unit. These LED’s can be categorized into 3 categories.
1.
Unit LED indicators.
2.
Communication with Compoway-F or Host Link LED indicators.
3.
PROFIBUS communication LED indicators.

Unit Led Indicators
The Unit LED’s indicate the status of the Gateway. These are the two highest
LED’s. In the next table there is an overview of all possible LED states of the
two Unit LED’s. A description of the error and a possible solution to solve the
error.
4-2-2
Compoway-F or Host Link LED Indicators
The Unit LED indicators show the status of the communication with compo-
way-F or Host Link. These are the two LED’s in the middle. In the next table
there is an overview of all possible LED states of the two Compoway-F or
Host Link LED’s. A description of the error and a possible solution to solve the
error.
