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.
