6.2 LEDs for Port 0 Serial Port
Some ProLinx modules have three extra serial ports. Each of these serial ports
has two LEDs indicating status.
LED Color Description
Off No activity on the port. Port 0 - ACT
Green Flash The port is either actively transmitting or receiving
data
Off Normal state. When off and Port Active led is
indicating activity, there are no communication errors Port 0 - ERR
Red On or Flashing Activity on this led indicates some communication
error was detected, either during transmit or receive
6.3 4101 Series 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 The Debug/Configuration mode is active (applies to modules that
support pass-through on Debug port - such as DFCM units).
If CFG LED is not on, 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 If Fault LED is on, the Debug/Configuration Mode is active (if the
module supports pass-through on the Debug port - such as DFCM
units).
If the Fault LED is off, 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 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).
