Software Overview
Scalibur is using a Linux operating system, which runs several applications in
parallel.

Scalibur software structure
2.2.1
Scalibur System Shell
The Scalibur System Shell is accessible only via the local USB-OTG port, and is
used during commissioning to configure basic settings like IP address, or as
maintenance access if IP address or passwords have been lost.
2.2.2
IO Server
The IO server controls the modular Inline terminals of the Scalibur station and
manages concurrent accesses to the hardware data points. Niagara and the IO
server communicate via an TCP connection. This allows to control IOs remotely
from another Niagara station. The remote access can be limited or disabled by the
setting of the IP address of the controlling station.
2.2.3
Commissioning Web Server
The commissioning web server is exclusively accessible via the local USB-OTG
port. It presents web pages to commission the device: setting IP addresses and time
zone, reading state of inputs and setting output states of the data points of the local
IO terminals for test purposes.
2.2.4
Sedona Virtual Machine
The Sedona virtual machine (SVM) runs the Sedona application in real-time with
configurable cycle time. The Niagara Workbench connects to the SVM to modify the
application, load updates, or create backups of the application. Platform specific kits
provide access to the IO terminals, and also to system settings like IP addresses
