Technical cornerstones
In order to achieve the shared objectives of operators and owners of automation systems,
we need a suitable stable technical foundation.
This foundation comprises 4 basic properties which are common to all Saia PCD® controllers.
1
Modularity in hardware and function enables high flexibility and adaptability at any time
during the lifecycle of 15…20 years.
2
Maximum portability: The project’s application software can be ported over all device
classes and device generations throughout the lifecycle; even by the owner/operator
alone.
3
Complete openness in communication. All device functions and data can be seen from
the outside and used. Complete openness also in licensing the SBC software tools,
because SBC software tools are available to anyone.
4
Standard technology only: The ICA functions of Saia PCD® devices are implemented using
standardized technology that is in common use and is recognized around the world
(web + IT). We do not use proprietary technologies. Saia PCD® S-Bus is the exception.
We need this in order to get right into the core of the Saia PCD® devices, e.g. debugging.
Shared objectives
Being able to understand and assess products and their integration into systems is essential.
Knowing what objectives they were created to achieve helps accomplish this. These objectives
should largely be identical to those of operators, planners and integrators of ICA systems.
Shared objectives bring everyone together – just as the shared methods and values of the
companies involved make collaboration easier and ensure success. The following two pages
provide a short overview of this.

other protocols can also be implemented later as a PLC program
