LED
Description
Ok
The module LED will provide information regarding the system-level operation
of the module. Thus, if the LED is red then the module is not operating
correctly. For example, if the module application firmware has been corrupted
or there is a hardware fault the module will have a red Module LED.
If the LED is green (flashing), then the module has booted and is running
correctly
without
any application configuration loaded.
If the LED is green (solid), then the module has booted and is running correctly
with
application configuration loaded.
A / B
The Ethernet LED will light up when an Ethernet link has been detected (by
plugging in a connected Ethernet cable). The LED will flash every time traffic
was detected.
This module has two Ethernet ports A and B. Each LEDs represents each
specific port.
Run
This LED will indicate the PROFIBUS operating mode when in Master mode
(Note that in Slave mode this LED is N/A).
Master
Solid Red
– The PROFIBUS network is in STOP mode.
Flashing Green
– The PROFIBUS network is in CLEAR mode.
Solid Green
– The PROFIBUS network is in OPERATE mode.
Off - The PROFIBUS network is OFFLINE.
Slave
Off
– For Slave mode this LED is N/A.
