4.1.4 LED
Indicators
LEDs provide visual indications of potential problems. The following LEDs are
fundamental to all ProLinx modules.
Base gateway 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. Check 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
R
ESET
p/b or
cycle power to clear error. If it does not clear after a reset, 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
R
ESET
button. It occurs after a cold/warm boot command
is received. It also occurs when a configuration is being downloaded.
Off Normal
operation.
Flashing
An error condition has been detected and is occurring. Check
configuration. May also indicate intermittent or periodic
communications errors on any application network port.
Err
Solid Red
This condition indicates of a large number of application
communications errors. The gateway's error flag is cleared at the start
of each command (master/client) or receipt of data
(slave/adapter/server) and set on whenever an error occurs. If this LED
stays on all the time, it indicates a complete loss of communication on
one or more application communication ports.
Mini-DIN 8 Serial Port
LED State
Description
Off
Normal state. When off and Port Active LED indicates activity,
there are no communication errors.
ERR
Red On or
Flashing
Activity on this LED indicates that some communication error
was detected, either during transmit or receive. To determine
the exact error, use the Debug port procedures described in
this section.
Off
No activity on this port.
ACT (Active)
Flashing Green
The port is either actively transmitting or receiving data.
