Introduction
Scalibur is a powerful modular controller for Niagara and Sedona. Scalibur stands
for scalability, a major characteristic of this controller. Scalability comprises several
aspects:
1) Scalable IO
A Scalibur station consists of the Scalibur controller and up to 63 terminals of the
modular Inline system. The terminals are available in a wide variety of types:
digital and analog inputs and outputs with different numbers of channels as well
as functional terminals for DALI light control, pulse metering, MBUS or serial
interfaces.
2) Scalable software
Scalibur has been developed primarily for the Niagara framework. Niagara
applications are built with the software tool Niagara Workbench. While Niagara
is very powerful, it is not very well suited for specific real-time applications. In
order to realize such applications with Scalibur too, the controller has the
Sedona framework in parallel to Niagara. Sedona applications run with fixed
cycle times in the millisecond range and are created with the
Niagara Workbench. Beside the separate exclusive use of either framework, the
parallel use of Niagara and Sedona is supported. The Niagara and Sedona
application can communicate to each other with a Sedona driver for Niagara.
3) Scalable licensing
The license model for Scalibur is very flexible: a license comprises a certain
number of data points which can be integrated with Scalibur. These license
packs are available as first-time license (250/500/1250/5000/10000 data points)
or as upgrade license (500/1250/2500 data points). Sedona, as open source
project, doesn’t have any license fees.
4) Scalable IP network
Scalibur contains two logically separated IP interfaces and an integrated
Ethernet switch with four external ports. The configurable assignment of the
Ethernet ports to the separate IP interfaces and the usage of the spanning-tree-
protocol allow flexible topologies like daisy-chain and redundant ring-structures
for both the backbone and the local control network.
