Do PLCs eliminate need for a DCS?
A PLC for process control can appear to be less expensive, but… Bill Lydon, contributing editor at Automation.com has talked with a number of control engineers that are trying to sort out this issue to make decisions.
In the past it was fairly easy to determine whether a PLC or a DCS was right for an application but in recent years this has become more difficult. It is argued that more powerful PLC products coupled with new software tools provide an integrated process control system rivaling a distributed control system (DCS) for process control applications.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
