Answers:
One step visual integration. Although ABB (and Siemens) have a fairly simple interface (I actually prefer Siemens use of Java Applets to ABB's Codesys Visualization) I would like to be able to quickly and efficiently use pre-programmed applets and objects to create the visuals for the programs.
~Ken S, Controls Engineer, Cumming, GA
Programmable in Java, Javascript etc. Dynamic memory allocation. Support simulink code i.e. code generation. Open protocols like JSON etc.
~Mattias Wallinius, Engineering Consultant, Lund, Sweden
Simpler I/O connectivity. Most I/O nowadays use some sort of cable and sub base and the sub bases take up a lot of panel space.

Answers:
Don't spend money you don't have to. Sure, the new ABB 590 series is great and will do things that some tablet PCs won't, but if you're just controlling a can-opener, you don't need the extras. Engineer effectively, but keep cost in mind ... we have a soft spot for the cool stuff and it can be difficult to say no to the latest and greatest electronics.
~Ken S, Controls Engineer, Cumming, GA
Make sure about sourcing and sinking cards, especially when upgrading from let say a MEDOC to a AB PLC, it is very important! And make sure you understand each card before purchasing (just the basic uses), it saves money
~Louis D, Progress specialist Engineer, Vereeniging, South Africa
Don't be dazzled with specifications from non-established manufacturers or by cheaper equipment from manufacturers who don't have extensive worldwide support and infrastructure.
~Greg D, Sneior Control Systems Engineer, Cedar Rapids, IA
Watch IO count per channel, Excessive IO on one or more channels can bottleneck the entire system.
~Jude W, Controls System Developer, Walton, KY
Please make the communication between PLC and other devices as user friendly as possible.
~Rohini Kp, Technical Support, Mumbai, India
Price don't reflect ease of use. Always save using different revisions.
~Derek J, Engineer, Lincoln, NE
Price is not the most important. A reliable sistem more important
~Santosa V, Research & Development, Pontianak, Indonesia
