Troubleshooting the operation of the DNP Master port can be performed using
several methods.
The first and quickest is to scan the LEDs on the module to determine the
existence and possibly the cause of a problem. This section provides insight into
the operation of the Serial Port status LEDs. Information on the module’s other
LEDs can be found in the ProLinx Reference Guide.
5.1 Common module LEDs
LED State Description
Off Power is not connected to the power terminals or source is insufficient
to properly power the module (800mA at 24vdc minimum required) Power
Green Solid Power is connected to the power terminals. Verify that the other LEDs
for operational and functional status come on briefly after power-up
(check for burned-out LEDs).
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
cycle power to clear error. If not, use the Debug procedures described
later in this manual.
Off Normal 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).
