The top 5 most read articles online, from May 1-7 for Control Engineering, covered DCS migration, the programmable controller’s origins, human-robot collaboration, safety integrity levels, and manufacturers not embracing IIoT. Links to each article below. 

1. Four things to remember about DCS migration

Whether it’s a refinery, chemical plant, or other process-related facility, the primary control system must operate efficiently, safely, and economically. If it doesn’t, perhaps it’s time for an upgrade.

2. Origins of the programmable controller and its potential future

The programmable logic controller (PLC) went through a lot of trial-and-error in its early inception. It has continued to develop since the 1970’s and the market is now converging toward Ethernet/IP-based control networks.

3. Robots, humans coming closer to each other

Hannover Messe 2017 opening a high-tech event with Schunk winning the 2017 Hermes Award for its collaborative robot and Poland, the event’s partner nation, emphasizing innovation.

4. Determine safety integrity level for a process application

Safety instrumented systems (SIS) are installed in process plants to mitigate process hazards and they must be assigned a target safety integrity level (SIL) during the process to determine what needs to be done next.

5. Manufacturers still not embracing IIoT

Seven manufacturing market trends for 2017, according to IHS Markit report at Hannover Messe, include more growth and an attention shift from remote cloud-based analytics to local and edge computing.

The list was developed using CFE Media’s web analytics for stories viewed on, May 1-7, for articles published within the last two months.
