LED Indicators

Troubleshooting can be performed using several methods.
The first and quickest is to scan the LEDs on the gateway to determine the
existence and possibly the cause of a problem. The gateway's LEDs provide
valuable information such as

The state of each port

System configuration errors

Application errors

Fault indications

Description
Power is not connected to the power terminals or source is
insufficient to properly power the gateway (208 mA at 24 VDC is
required).
Power is connected to the power terminals.
Normal operation.
A critical error has occurred. Program executable has failed or
has been user-terminated and is no longer running. Press
theResetbutton or cycle power to clear the error.
Normal operation.
The unit is in configuration mode. Either a configuration error
exists, or the configuration file is currently being downloaded or
read. After power-up, the configuration is read, and the unit
implements the configuration values and initializes the hardware.
This occurs during power cycle or after the Reset button is
pressed.
Normal operation.
An error condition has been detected and is occurring on one of
the application ports. Check configuration and troubleshoot for
communication errors.
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).
