Saia-Burgess Controls - PLC Values and culture

Value and culture of a PLC company
We develop our products so that they give our customers direct added value when they use them, by earning them money for a very long time.

This requires products with a long lifecycle of problem-free, reliable operation. Previously installed products must always be capable of adaptation to changed needs. Investments made by the customer should not be constantly wiped out by incompatibilities or forced innovations that no-one requested.

This is why we attach such great importance to PLC-based technology, with its sustained customer benefit and ease of upgrade. For more than 50 years, our company has remained true to these values.

Since application settings all too often fail to behave in accordance with the standards, we made Saia® PCD1,2,3 control technology more robust against interference than the CE standard requires. We set high standards for ourselves. This brings our customers greater security and peace of mind.

CE Norm

Alongside the strict IEC 61131-2 PLC hardware standard, Saia® PCD control technology also meets the stringent requirements of various testing authorities for marine engineering.

IEC EN 61131-2: Design- and productionquality This standard defines in 150 pages how electronic items should be developed and produced to satisfy PLC quality requirements. It ensures, among other things, that service is possible even without specialists. Look out for the extension «-2». Many suppliers only work to PLC standard 61131-3. But that standard only defines the programming type, regardless of the hardware/design quality. In addition, standard 61131-3 does not specify the portability of application software from one device series to another, nor from one hardware version to the next.

View of lifecycle for Saia® PCD control equipment
Compatibility and free portability safeguarded over an entire product generation.

Control and automation electronics should have the same lifecycle as the installation technology. Within this cycle, it must always remain adjustable and expandable. It should therefore be modular and in PLC quality.		The compatibility and free portability of system/machine software is safeguarded over an entire product generation of 18 to 25 years. This will only work if one develops all the engineering software oneself, relying consistently on «interpreted program code». This requires rather more hardware resources, but allows user software to be portable across several controller generations.
