Module Identification
The LEDs on a PNS module can be commanded to repeatedly turn ON and OFF in a special
sequence, to help locate or identify the module.
Revision Axxx:
•
•
Revision Bxxx or later:
•
•
The Module Identification LED Pattern is initiated by the PROFINET DCP Identify Device
command. Module Identification can be initiated using the PAC Machine Edition Discovery
Tool by refreshing the device list, double clicking on the RX3i PNS module, and clicking the
Identify Device button on the PNS properties pop-up window.
Microprocessor Over Temperature
If the maximum threshold temperature for the PNS's microprocessor is crossed, the PNS
goes into power-saving mode. While the PNS is in an over-temperature condition, the
following blink patterns are alternated on units Rev. -Axxx:
•
•
Rev. -Bxxx unit will turn all LEDs off. The PNS stays in power-saving mode until the
temperature drops to a safer level. Once a safe temperature is reached, the PNS module
restarts.
Note:
Firmware Update
While the PNS Rev. -Axxx is in firmware update mode, the OK, LAN, and STATUS LEDs blink
Green for 0.5 seconds and then off for 0.5 seconds in unison. During firmware update
operation, the ports are disabled, so all the PORT LEDs are off and the CONNECT LED is off.
The USB LED operates normally displaying the condition of the USB port.
LED Operation and Connector Details
First the green LEDs are turned on in the following circular order: OK, LAN, STATUS,
CONN, PORT 4, PORT 3, PORT 2, PORT 1. There is a short delay between turning on
each LED.
The LEDs are then turned off in the same order. There is a short time delay between
turning off each LED.
First the green port speed LEDs are turned on in a circular order. There is a short delay
between turning on each LED.
The LEDs are then turned off in the same order. There is a short time delay between
turning off each LED.
PORT "1", PORT "2", and STATUS LEDs turn on RED for 0.5 seconds (all other LEDs
off)
Then PORT "3" and PORT "4" LEDs turn on RED for 0.5 seconds (all other LEDs off)
Under certain ambient operating temperatures, the PNS may momentarily display the over
temperature pattern during power-up while it is calibrating its thermal protection functions.
This indication can be ignored.
