Troubleshooting the operation of the DNP Slave 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.
6.1 Base Module LEDs
LED State Description
Off Power is not connected to the power terminals. This LED is hardware
driven, so it only requires power to operate. Power
Green Solid Power is connected to the power terminals. Verify that the other LEDs
for operational and functional status.
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 the configuration mode. The configuration file is being
read and 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. Check
configuration.
Err
Solid Red This condition is indicative of a large number of errors in the
application interface communications. The module's error flag is
cleared at the start of each command (master/client) or receipt of data
(slave/adapter/server).
