LED indicators provide a means of monitoring the operation of the system and
individual ports. There are extremely useful for troubleshooting. The gateway
provides LEDs to help monitor each port. In addition, system configuration errors,
application errors, and fault indications are all indicated by LEDs, providing alerts
to possible problems.
6.1
Common gateway LEDs
LED State
Description
Off
Power is not connected to the power terminals or source is insufficient
to properly power the gateway (800mA at 24vdc minimum required)
Power

Off Normal
operation.
Fault
Red Solid
A critical error has occurred. Program executable has failed or has
been user-terminated and is no longer running. Press Reset p/b or

operation.
Cfg
Amber Solid The unit is in configuration mode. The configuration file is currently
being downloaded or, after power-up, is being read, the unit is
implementing the configuration values, and initializing the hardware.
This will occur during power cycle, or after pressing the reset button. It
also occurs after a cold/warm boot command is received.
Off Normal
operation.
Flashing
An error condition has been detected and is occurring on one of the
application ports. Check configuration and troubleshoot for
communication errors.
Err
Solid Red
This error flag is cleared at the start of each command attempt
(master/client) or on each receipt of data (slave/adapter/server); so, if
this condition exists, it indicates a large number of errors are occurring
in the application (due to bad configuration) or on one or more ports
(network communication failures).
