Firmware Updates
The PROFINET Scanner enters firmware update mode when commanded to do so from the
Winloader update utility, or if a firmware component is corrupt or invalid.
In firmware update mode, the PROFINET Scanner module blinks its LEDs in a special pattern
as described previously, and its Ethernet ports are not operational.
If the PROFINET Scanner is currently in use by an IO-Controller and the controller is in Run
mode, all attempts to update the PROFINET scanner firmware are rejected.
If the PROFINET Scanner 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 PROFINET Scanner is rebooted, its previous
connections are re-established and control resumes.
Firmware Update for Modules in the Remote Node
VersaMax modules in the remote node that support firmware updates can be updated via the
PROFINET Scanner using Winloader. The computer running Winloader attaches to the USB
port on the PROFINET Scanner. The module being updated is described by its slot location in
the VersaMax node.
A module cannot be updated while the PROFINET Scanner is actively communicating with an
IO Controller that is in Run mode. If the IO Controller is not in Run mode, communications with
the IO Controller are stopped, the update proceeds, and communications are rejected until the
update is complete.
During the I/O module firmware upgrade process, the CONNECT LED blinks Amber to indicate
that the PROFINET connections are being blocked for the update. The module's Ethernet ports
remain operational and its other LEDs continue to operate normally. The PROFINET Scanner
sets module outputs to their configured defaults.
When the firmware update on a module has completed, previous connections are re-established
and control resumes.
