PLC vs. DCS - Competing Process Control Philosophy
Automation.com, October 2011
By Bill Lydon
The idea of using a PLC-based system rather than a DCS has become a philosophical and technical debate in the industry. DCSs have been the primary solution for process automation but now many PLC vendors are arguing that a single integrated architecture based on PLCs and/or PACs is the best approach to total plant automation.

The Perils of a DIY Distributed Control System  
Automation.com, September 2011
By Tim Sweet, Honeywell Process Solutions
For certain industries, a distributed control system (DCS) provides substantially more value as the basis for automating the plant than a programmable logic controller (PLC)-based system. When PLCs and HMI software packages are integrated, the result looks a lot like a DCS. But, all is not as it seems.
