Strategic or mission-critical embedded computing projects can have a lifetime measurable in years or even decades. Throughout that time, there is a continuous requirement of maintaining and improving the performance of the total system; ensuring that it is always able to be serviced and supported, preferably at minimum cost and with minimum disruption. This white paper describes GE Fanuc Embedded Systems’ approach to providing that cost-effective, long-term support, with emphasis on minimizing the impact of component obsolescence.
