1. Programming PLCs: Keep the documentation clear and simple

Poor programmable logic controller documentation and housekeeping can lead to unnecessary troubleshooting and downtime. Keep it simple in order to avoid the possible risks and confusion. 

2. Smart I/O systems vs. fieldbus networks

New configurable I/O systems bring greater flexibility to conventional instrumentation. How do they stand up to fieldbus networking for capabilities and convenience? 

3. Programming in motion

Case study: Automated Industrial Machinery (AIM Inc.) moved from an analog interface to servo amplifiers to a digital motion control network to reduce wiring and simplify programming. It used IEC 61131-3 compliant software and industry-standard PLCOpen function blocks. See examples. 

4. 7 things noncontrol people should know about control engineers

A few basic differences between control engineers and others in the plant can hinder progress toward optimization. Start a conversation to improve communications and controls. See examples and career advice. Send a link to these seven things other people should know about control engineers, so they understand.

5. Centralized controls: Smart software, networks trump smart hardware

Machine architectures require many field devices. For easier system design, engineers should select a core control platform that minimizes complexity, with a unified software platform and network. More streamlined hardware and networking architectures are easier to implement, support, and maintain. 

The list was developed using CFE Media's web analytics for stories viewed on controleng.com, June 2-8, for articles published within the last two months.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
