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).

SCADA Systems ‘Dampen’ Infrastructure Problems

The southern tip of California's Marin county is separated from the city of San Francisco by the most famous mile-long strip of steel and concrete in the world. Yet, within a 10-minute walk of the Golden Gate's Marin terminus begins a county-wide network of California Wildlife Service signs warning against mountain lion attacks.

ISA TECH/97 Highlights From Anaheim, Calif., Day Three

OPC on the ISA TECH/97 Floor OLE for Process Control (OPC) was demonstrated on the floor at ISA TECH/97. Based on Microsoft’s component object model technology, OPC allows components in a networked system to share process data. The Microsoft and OPC booths demonstrated the interoperability of products from 16 foundation members. The booth demonstrations show real-time data flowing between hardware such as programmable logic controllers and distributed I/O from various manufacturers to human-machine interface and supervisory control and data acquisition software systems over Ethernet using TCP/IP.

ISA TECH/97 Highlights From Anaheim, Calif., Day Two

Boeing Explores Development of ‘Smart’ Transducer Bus Lee Eccles of Boeing Commercial Airplane Co. began his presentation in the ‘Use of Automation to Enhance Productivity in the Aerospace Industry’ by asking the question ‘why bother?’ In structural sensing and testing of airplane wings and fuselages at Boeing, a lot of effort goes into simply setting up the test. Structures for destructive testing of a wing or testing flight-control actuators require huge setup times.
