MP Series Controller LEDs
There are five LEDs on the front panel of the MP Series controller.

The MP Series controller Ethernet and Status indicators comprise two LEDs (green/yellow and green/red respectively) in one structure.
The LEDs indicate status of the MP Series controller and the ongoing communication.
Status LED
The MP Series controller Status LED indicates the condition of the device.

LED Patterns |
Condition |
|
Green, constant |
Normal operation, status OK MP Series controller firmware application running |
|
Green, flashing (~1 Hz) |
Device restarting, wait MP Series controller firmware application running |
|
Red, constant |
Detected error, attention required |
|
Red, flashing (~1 Hz) |
Device operates, but a problem needs attention |
|
Red/green, flashing (~1 Hz) |
MP Series controller I/O board receiving software upgrade, wait Do not interrupt power to the controller. For more information, see the following Important note. |
|
Amber, constant |
MP Series controller firmware boot applet running |
|
Amber, flash |
Device restarting, wait MP Series controller firmware boot applet started |
|
Amber/green, flashing (~1 Hz) |
MP Series controller firmware is being upgraded. It is typically the firmware main application, but it can also be a boot applet. |
Avoid power interruptions to the device during the brief period when the Status LED is flashing red and green. An interruption causes problems with the I/O processor upgrade and can result in corrupt firmware. You can view the evidence of a corrupt processor when the device reports itself as an “MP-C-15A.” A corrupt I/O processor can lead to the loss of the reset button and/or I/O functionality, as well as the inability to upgrade the I/O processor and/or the device.
Sensor Bus LEDs
The Sensor Bus LEDs indicate the condition of the sensor bus data communication.
