F&eIT Protocol Specifications
The sudden spread of the Internet has resulted in networks springing up in a wide range of fields.
This, in turn, has resulted in the appearance of many information devices that make use of this
infrastructure. Yet, it is a fact that interconnectivity - the greatest advantage of networks - is not being
used to its fullest. CONTEC sees networks as a prime part of the system bus concept and has
developed distributed monitor & control networks that organically integrate various applications from
corporate offices through to field applications.
