PID Loop Tuning

In your recent "How Software Tools Simplify Loop Tuning" article [Control Engineering, Nov. 1997, p. 89] you imply that ExperTune connects only to PLCs. ExperTune has a DDE connection that connects directly to Fisher/Provox (via SIU, HDL), Honeywell TDC systems (using GUS workstations), and Bailey DCS (via SIU).

In your recent "How Software Tools Simplify Loop Tuning" article [ Control Engineering , Nov. 1997, p. 89] you imply that ExperTune connects only to PLCs. ExperTune has a DDE connection that connects directly to Fisher/Provox (via SIU, HDL), Honeywell TDC systems (using GUS workstations), and Bailey DCS (via SIU). For single-loop controllers ExperTune also has a standalone data acquisition unit, that periodically samples analog values of process and control variables directly from the controller's I/O ports.

You fairly assess that "ExperTune does all the work." You did not mention that ExperTune has advanced analysis available: power spectra and auto/cross correlation, Bode plots, and first or second order filter design.

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.
