Additionally, Niagara provides powerful tools to analyze the communication in
connected automation networks.
Before starting a detailed analysis, make sure that the device is properly wired,
supplied and has finished booting. Check especially

if all IO terminals are properly interlocked and connected by their feather
keys/keyways

if the mounting rail is properly grounded

if the functional earth connector of the device is connected using a 1.5 mm²
(AWG ) wire with the mounting rail via a earthing clamp

if the LEDs UM, US, UL are permanently on

if the power supply voltage is within the allowed tolerance range

A good indicator are the tree software status LEDs (see 3.3.3). Only if they
are regularly blinking, the boot process has finished.
5.3.1 SCA System Shell / Commissioning Website is not accessible
Both of these need an USB cable from the PC USB port to the Mini USB port of the
Scalibur.
Please verify that the cable is not damaged and is properly plugged into both
sockets.
Check if the Device Manager shows the device
Remote NDIS Compatible Device
is
shown as
Network adapter
. If not, re-install the device driver (see 3.2.5).
5.3.2 IP Address unknown
The IP addresses of the Scalibur can be shown and modified via the SCA System
Shell or the commissioning website. Both accesses work independent of the current
IP settings via a local USB connection (see 4).
5.3.3 No IP Communication
The command ping allows to test the Ethernet connection between two devices. The
SCA System Shell provides a ping function.
Please check first the proper connection of the Scalibur to the Ethernet using the
Ethernet status LEDs.
Then, the IP addresses and subnet masks of all devices that shall communicate with
each other. Especially ensure unique IP addresses and proper subnet settings.
5.3.4 Unknown Niagara Platform Access Credentials
If the access credentials are lost, they can be reset to their default value (user
sysmik / password intesa ) with the Service button (see 3.3.6). The Scalibur has to
be restarted and the Service button must be pressed at the right moment.
