Abstract Bubbles


Sigma is an independent supplier of Process Control and Factory Automation solutions. We embrace technologies and systems with an open systems approach, which enables industrial systems to be engineered for the future.

This is typically characterised by the use of IEC 61131.3 programming environment, the use of distributed peripheral bus systems, device oriented control networks and the use of pre engineered library of device blocks - reusable software.
