We see from your search that you're looking for information on the term "Digital Communications",
and we have a large number of manufacturers' news releases and technical articles here on Processingtalk which will be of interest.
Let me be your guide.
Start with
the news release Eurotherm market success with EPower controllers from
Eurotherm, which we summarised at the time by saying "Eurotherm has thrown down the gauntlet to other power controller suppliers with the launch of its new range of EPower Controllers, which set a new standard in efficiency and flexibility".
The day before,
we featured the news release A SmarT dosing and filling controller for Europe! from
Penko Engineering: "Don't you ever wish for a simple controller that will just do what you want instead of forcing you into complicated programming, wasted time and excessive expense? SmarT is what you are looking for".
In January 2008, we covered the news from Control Techniques
concerning its Digitax ST
- take a look at Control Techniques launches new servo family
which says: "A new range of servo-drives, the Digitax ST, is launched with unprecedented connectivity, feedback options, intelligence and functionality, targeting the general machinery automation market".
Take a look also at the news release from National Instruments, Teaching analogue and digital communications,
as well as Modbus white paper available from Moore Industries from Moore Industries International,
and Coal-fired power plant reduces costs with Foxboro from Invensys Foxboro.
