Terry Blevins — Mon, 17 Jun 2013 12:00:00 GMT

The ISA104 Device Integration committee was established to develop or adopt, and to facilitate the application of standards and technical reports that represent device and interface descriptions for access of field devices in automation systems. In 2012 the scope of the committee was expanded to include the promotion of the Field Device Integration (FDI) standard, …

SGA, you can e-mail me at my sign-in name at aol.com to let me know what features of DeltaV your database uses. My utility only handles features that I've seen in an FHX file. I haven't seen batch features in an FHX file, so the utility does not support them. Wireless I/O is a work in progress, but I hope to have full support for it soon.

Forum Post: RE: FHX to XML converter

Jack_France — Fri, 07 Jun 2013 09:39:00 GMT

Hi István

I'm glad that everything is back in order.

No reverse tool for two reasons:

-1 - I do not want to take responsibility for import problem in DB - too risky

-2 - In the FHX file, some items contain binary data (normal or not, I do not know how) encountered in the definition of material manufacturer. When FHX treatment to XML, these items are treated as abnormalities and resulted in replacement of the symbols (a triangle) and documented comments with binary values encountered.

These data must be manual processing (if they are interesting).

Thank you for this previous link about conversion, but sending confidential industrial configuration to the net is risky and is not suitable for large files such as a full DB that can be up to several hundred of Mb.

I test my converter with full DB export FHX file up to 218 Mb (near 15 minutes treatment).

When processing large files, we sometimes feel that the tool is fixed (stall) and seems to bug, but to avoid consuming too much memory, it processes with smallest data packets as possible, but it is sometimes necessary to grow its buffer to retrieve very large indivisible sequences, giving the impression of not advancing, but I've never had a crash.

Finally, about Emerson conversion tools provided (with no result waranty) in the deltav/bin folder, I have never generate a valid XML file with it (truncated datas, no information about successfull or abnormal completition and so on)

Yes, providing you don’t exceed the OPC point count for the application station. Pi would be another client to the DeltaV OPC server just as OPC Mirror is a client.

Forum Post: RE: Proplus download error

István Orbán — Wed, 05 Jun 2013 12:03:00 GMT

Hi,

I recently ran into the same message. It happened after I reassigned an equipment module to one controller to the other. I ran into some problems, I deleted the module from the old controller and then tried to download it to the new controller (from DeltaV Explorer). I solved it by downloading the module from Control Studio.

I would say that the cause had something to do with linked composites: some of the composites which were on the old controller were not downloaded to the new controller before downloading the equipment module, so it did not find their definitions and the download failed.

So, basically I am still not sure about the cause but the solution seems to be to download the faulty module from control studio.

Forum Post: RE: Water density calculation given pressure and temperature.

LouHeavner — Wed, 05 Jun 2013 05:19:00 GMT

I don’t know the application that spawned the original request, but happened on the same need for water density, recently. It was a waste heat steam generator application and we had to provide 3 element steam drum level control. There is more than one way to configure this, of course, but we were essentially using feed forward to the level controller PID loop effectively ratioing boiler feedwater volumetric flow (GPM) to produced steam mass flow (KPPH). We had to provide a feed forward gain and it depends on the density of the boiler feedwater. In our case the temperature doesn’t vary enough to warrant dynamically updating the FF gain, but in some applications it might.

"These laws would be useful if I needed equations relating to gases."some of these laws also apply to liquids.

Could you give some more information about the process you want to measure.

The weight(mass) of the water stays the same, only the volume changes when the temperature changes.

If you use a PD measurement then you will get the correction automaticly ?

If you use height measurement then it´s and other thing..

If you are able to install the opc client on the dv opc server, ensure the client is set to run under the authority of a OS user that has link to deltav application user capable of reading /writing the parameters/fields for the areas in which the values reside. Typically, the user will have the operate key sitewide.

In the DeltaV control system, this information is provided using a robustness plot that shows gain margin and phase margin as illustrated below. Information on this type …

Forum Post: RE: safety functionality to detect if a manual valve is open or closed

mohdismail.khan — Fri, 31 May 2013 06:16:00 GMT

You need to purchase a 1420 Smart Wireless Gateway to gather data from the Fisher 4320 Wireless Position Monitor devices and pass to the control system.

Please note that one 1420 Smart Wireless Gateway can cater upto 100 wireless devices!

You can read further about the 1420 Smart Wireless Gateway capabilities at the below link

www2.emersonprocess.com/.../SmartWirelessGateway.aspx

You can learn more about Emerson Smart Wireless at the below link

www2.emersonprocess.com/.../WirelessHomePage-Flash.aspx

You can check first if there is a mounting kit already available for the size, model and brand of the valve you are using in your plant. As I wrote earlier, we already have predesigned mounting kits available for major valve brands.

In case it is not available, a new mounting kit can be custom made for your need.

I hope this would help you better understand about the feasibility of the technology.
