Q:
What new technologies are influencing programmable logic controller design?
33 answers
Answers:
In my day to day, the networking technologies are most important to PLC design. Being able to easily pass information and control to a computer both locally and globally is at the forefront of my design work.

Q:
From your perspective, which companies are creating the most innovative programmable logic controllers?
44 answers
Answers:
I like ABB for their ease of use. Setting up a plc or drive is simple and their integration of ideas that make life easier in engineering and the field are cutting edge; (i.e. the ethernet cable extension for the drive controller so programming can be done through the keypad without crouching into the drive space).
~Ken S, Controls Engineer, Cumming, GA
Tridium, Deos, Alerton, TREND CONTROLS, TAC,... all these companies have advantages, and also disadvantages
