Special LED Pattern - Module Identification

The LEDs on a PNC001 module (PNC001-Ax only) can be commanded to repeatedly turn ON
and OFF in a special sequence, to help locate or identify the module:
• First the LEDs are turned on in the following order: OK, LAN, STATUS, CONFIG, 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.
For the -Ax version, the command, blinkId <begin/end> is issued via the Command Line
Interface. Issuing the blinkId begin command starts the identification blink sequencing
while the blinkId end stops the identification blink sequencing. When issued from the
Command Line Interface, the last command session that commands the IDENTIFICATION
blink pattern determines its state (either blinking or stopped). Note that the blinkId
command requires Modify-level access to the Command Line Interface.
5.2.2 Special LED Pattern - Microprocessor
Overtemperature
If the maximum threshold temperature for the microprocessor is exceeded, the PNC001
goes into power-saving mode. While the PNC001 is in an overtemperature condition:
• the LEDs on the PNC001-Ax module behave as follows:
• PORT 1, PORT 2, and STATUS LEDs flash red for 0.5 seconds (all other LEDs off),
then PORT 3 and PORT 4 LEDs flash red for 0.5 seconds (all other LEDs off).
This pattern repeats.
• the LEDs on the PNC001-Bxxx module behave as follows:
• the PORT NUMBER LEDs flash red for 3 seconds and
then all LEDs turn off.
This pattern does not repeat.
The PNC001 stays in power-saving mode until the temperature drops to a safer level. Once
a safe temperature is reached, the PNC001 module restarts. When the PNC001 is restarted,
it retains any entries in its Local Log table and its non-volatile configuration parameters. For
the -Ax version, any debug data in non-volatile storage can be viewed from the Command
Line Interface using the log or show log commands.
Note:
5.2.3

Firmware Update

While the PNC001 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,
Diagnostics
Under certain ambient operating temperatures, the PNC001 may momentarily display
the overtemperature pattern during power up, while it is calibrating its thermal
protection functions. This indication may be ignored, and no overtemperature entry is
added to the Local Log table, the Controller Fault Table or I/O Fault Table.
