Invensys supports a large number of SCADA systems products supporting the supervisory control of many large infrastructure projects. The products themselves have extended life-cycle support.  These products are supported through last time buys, re-design and other means of functional replacement to make sure end of life components are available to enable manufacture to proceed throughout the service life of the products. 


This post is a fictionalized story of the kind of issues that are considered when doing upgrades for systems installations. Any resemblance to a particular site, people or customer is purely coincidental and the story could be set anywhere and in reality might result in a totally different outcome.
