Standards based wireless moves forward...

...aha! You thought I meant ISA100, didn't you?  Well, there are other standards-based wireless efforts underway that impact directly the field sensor space in the process industries. None of them are as far along as ISA100.11a, or WirelessHART, and none are backed by any major sensor or transmitter or controls...

You heard it here first-- ISA and HART agree to collaborate

As I told you all in this blog after ISA, the fix is in. There will not be, God willing and the creek don't rise, another fieldbus war around the wireless standards for industrial plants. Here's the official release from ISA and HART Communication Foundation: ISA and HART Communication Foundation...

But where's the OTHER wireless press release?

You know, the one where ISA and the HCF jointly announce that WirelessHART is going to become part of the ISA100.11a standard? The one that announces the end to the wireless war? Why haven't we seen that one? We know there's a deal. I have described it in this blog.

Just to keep us all honest, HCF brings out the elephant guns again.

Last week, as this blog reported, those responsible for way, way more than 50% of the revenue of the entire automation industry trooped into the SP100 meeting and made their feelings known. Whether it was because of them, or despite them, we arrived at a consensus compromise.

One last thing from the SP100 closing plenary...here's the deal...

At the SP100 Closing Plenary, SP100 co-chair Wayne Manges announced the compromise to include the WirelessHART specification into ISA10.11a as "inclusion by accommodation in Release 1," using a dual network, single gateway model, and considering interchangeability in Release 2. "Unless," he clarified, "there are technical reasons why interchangeability is not possible.

Honeywell is on board at SP100

In an interview this morning, Honeywell's Global Wireless Director, Jeff Becker, went on the record to declare, "We are fully in support of the compromise worked out by the SP100 dot11a committee. We understand it to be a dual-network single gateway compromise in Release 1 moving to complete interchangeability and...

The ISA SP100 Plenary Session convenes...

Wayne Manges and Pat Schweitzer convened the plenary meeting by going over the groundrules. Nick Sands from DuPont and the Standards and Practices Board, who with Marty Zielinski of Emerson Process Management, is the Managing Director of SP100, gave an inspiring little talk about what "consensus" really means and warned the...

Does SP100 WANT to accomodate WirelessHART?

That appears to be the real issue. Several of the most technical members of the committee have explained that they believe that it is relatively minor impact on ISA100 to accommodate WirelessHART. "I am not hearing anybody suggesting that SP100 should be adopting WirelessHART without any changes.

Can SP100 merge with WirelessHART?

After a parade of speakers from the HART Board of Directors, including Peter Zornio from Emerson, Gareth Johnson and Pat Cashwell from ABB, and speakers from Siemens and Endress+Hauser strongly recommended that at the very least, ISA100 incorporate the WirelessHART standard and at best, recommended that WirelessHART be adopted as...

PTO, FF and HCF put more pressure on wireless cooperation

In a joint press release to be issued this morning, the Fieldbus Foundation, HART Communication Foundation, and the Profibus Nutzeroganization (PTO) will announce the formation of a "Wireless Collaboration Team" aimed at producing a single "common interface to a wireless gateway." The release says that the three organizations "have also agreed...
