Technological advancements in process monitoring, control and industrial automation over the past decades have contributed greatly to improve the productivity of virtually all manufacturing industries throughout the world.
While 90% of global production is still controlled by analog instrumentation, almost all the controls installed as a part of a new plant or plant expansion are Digital Control Systems DCS connected by digital networks.
Nowadays, in this era of digital buses, one can plug in a laptop or use a wireless hand tool to instantly establish access to all the data, displays and intelligence that resides anywhere on the DCS network. This capability, in combination with the self-tuning, self-diagnosing and optimizing features of modern process control, makes both startup activity and operational routines much easier and more efficient. !! gg
