Firmware Updates
The PAC8000 PROFINET Scanner enters firmware update mode when commanded to do so
from the Winloader update utility, or if a firmware component is corrupted or invalid.
In firmware update mode, the PNS module blinks its LEDs in a special pattern as described
previously, and its Ethernet ports are not operational.
If the PNS is currently in use by an IO-Controller and the controller is in Run mode, all
attempts to update the PNS firmware are rejected.
If the PNS has experienced a fatal error, the module goes to an LED blink code error
condition and does not communicate with Winloader, causing Winloader to return a timeout
failure indication. The module must be restarted or power-cycled before reattempting the
update.
When the firmware update is completed and the PNS is rebooted, its previous connections
are re-established and control resumes.
2.11.1

PAC8000 PROFINET Scanner does not support firmware updates for IO modules.
