ISA Automation Week – Nov 5-7

ISA Automation Week is one of the major conferences conducted each year in North American. This year the conference will be held November 5-7 at the Nashville Convention Center, Nashville, TN. The convention center is convenient to reach – just eight miles away from the Nashville International Airport.

A number of standards groups conduct meetings the day before the conference opens. In particular, the ISA104 committee, Device Integration, which I chair, will meet Monday, Nov 4th, from 8:30-10:30 am in the Fisk 2 conference room of the Renaissance Nashville Hotel, 611 Commerce Street (across the street from the convention center). This ISA104 meeting is open to visitors so I would like to invite you to sit in on this meeting if you plan on attending ISA Automation week. One of the highlights of the meeting will be a presentation by Stephen Mitschke, Fieldbus Foundation, on Field Device Integration (FDI) – The Key to Interoperability.

As part of the conference technical program, a number of papers are presented later in the week. On Tuesday, Nov 6, during the afternoon session of Asset Management Track (3:45-5:15 pm), two member of ISA104 – Stephen Mitschke, Fieldbus Foundation, and Ludwig Winkel, Siemens – will present a paper titled FDI Meets Plant’s Device Integration Needs . The paper abstract is:

  •  The future is digital, and digital should be intuitive and easy to use. However, some users of 4-20 mA/HART, FOUNDATION fieldbus, and PROFIBUS devices have to grapple with two sets of files – EDD files and DTM1.2.x software drivers – to integrate devices into their systems. Field Device Integration (FDI) is a new device integration technology based on EDDL, and which includes elements of FDT2, providing a single device package that can be used on any system. The NAMUR chemical industry user organization has released 17 new user requirements for FDI over and above the circa 35 device integration technology requirements in their NE105 recommendation. The FDI technology has been designed to meet these plant needs, which includes investment protection, robustness, easy system administration, easy to use devices, interoperability, and easy migration.

As part of the Secure Wireless Control & Risks Track on Thursday, 7 November 9:15 a.m. – 10:45 a.m., Marty Zielinski, Emerson Process Management, and I will present a paper titled Using Wireless Measurements in Control Applications. The paper abstract is:

  • Wireless transmitters may be preferred in applications where new measurements are required since the cost may be lower than that associated with installing wired transmitters. However, there is a significant difference in the frequency and manner in which a new measurement value is updated by a wired transmitter vs. a wireless transmitter. Such differences must be taken into account when a wireless measurement is used in closed-loop control. In this paper we examine how the PID has been modified to address control applications using wireless devices. The differences between this modified PID, known as the PIDPlus, and the traditional PID are discussed. Test and field test results are presented that show that the same quality control as wired PID can be provided by PIDPlus despite slower, non-periodic wireless measurement update.

You may find these presentations of interest If you want to learn more about the Field Device Integration (FDI) standard, IEC 62769, or are considering using wireless measurements in a control application.
