Forum Post: Emerson Ovation DEH - Feedback control loops

Anand — Wed, 19 Jun 2013 12:00:00 GMT

In the Ovation based DEH for Steam Turbine Controller, there are feedback control loops like MW Controller and Imp Pressure Controller. When none of these feedback control loops is 'IN', how is the setpoint for Governing Valves derived?

Forum Post: DeltaV response time

Pun — Tue, 18 Jun 2013 16:20:00 GMT

Hi Can the DeltaV controller able to handle following response time:

1.Digital SOE inputs scan rate 0.001 second.

2. Modulating control logic and calculations process at every 0.5 second with the capability to process at least 10 percent of the logic at a 0.1 second interval.

3. Alarm display and operator command respond in not more than 1 sec

Forum Post: Surge arrestors and proplus

Pun — Tue, 18 Jun 2013 15:50:00 GMT

Hi,

I need advise for following:

1. In FPSO, is it necessary to provide surge protector for every i/o ? Is there anyway we can cut the cost by providing less number of surge arrestors, maybe just to power supply?

2. Can DeltaV have 2 proplus on same deltaV network to act as redunancy?

You may have seen the news of a next generation of portable vibration analyzer, the CSI 2140 Machinery Health Analyzer. Portable vibration analyzers are great for providing advance warning of machinery failures as part of a predictive maintenance program. The CSI 2140 provides a significant technology improvement over the CSI 2130, long known for its [...]

Forum Post: RE: SOE, AMS, OPc and Historian

Andre Dicaire — Mon, 17 Jun 2013 15:40:00 GMT

My thoughts on this:

1. The Pro Plus includes a license for the Event Chronicle, and AMS is expected to be installed on the Por Plus. The SOE database is an option on the Event Chronicle. There is no issue running these together from a compatibility perspective. For small systems (< 2000 DST's), we consolidate AMS and the Event Journal on the Pro Plus Workstation. As Youssef mentions, you want to be careful running all possible applications on the same box. You can enable the Historian on the Pro Plus, and it is limited to 250 tags. If you want to run VCAT or Terminal Services, you have to run the Pro Plus on a Server Platform. All these software are tested to run together. But you should consider two things: System Performance and Availability. AMS and the Event Chronicle databases are separate from the Pro Plus engineering functions. You should consider moving these to a dedicated App Station, both for performance on the Pro Plus and for seperation of these tasks. If you have need for a limited number of concurrent Engineering sessions, you can add RDP services to your Pro Plus (server). If you want RDP Operator Stations, which run 24/7, you should dedicate an RDP server so that the pro plus is not critical to operations, allowing for easier system upgrades and maintenance.

2. An OPC server is also available at 250 tags on the Pro Plus, but can be increased to 500 OPC tags with the EXCEL ADDIN license.

3. Yes, for 2 or more years. Disk space is your limiting factor. The DeltaV Historian supports long term data storage and PHV provides the tools to quickly view data back in time. As explained in some of these other threads, you need to move active datasets to extended Data sets, and then it is simply a matter of Hard Disk space. DeltaV Continuous Historian uses compression to optimize data storage, so that large time spans can be stored with minimal disk resources. This is a major feature of DeltaV over some of our competitors. Note that if a user prefers to use PI Enterprise, DeltaV PHV can access data stored in PI, provided the PI tags match the DeltaV hitorical parameter tags.

4. Yes, and it is very easy. PHV supports command line parameters to allow it to be launched in context, and some of these deal with start and end times. PHV also provides easy scrolling in time. Data access of back in time data is very fast.

5 Youssef covered this well. The DeltaV Continous Historian comes with a single user OPCHDA server. This allows one client application at a time. If concurrent access is needed (say an Enterprise scanner and a user client application) then you will need to add OPCHDA clients to the Historian. The Excel Add in for historical data does not use the OPCHDA server, so access is allowed while the OPCHDA server is connected to a scanner.

The History Analysis Webserver allows access to both the Event CHronicle and Continuous Historian, as well as the Batch Historian (if present) to allow historical data analysys, and this also provides tools for exporting history data to Excel. This is intended primarily for data analysis, and remote access via the web service for secure connections through the enterprise firewalls.

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.
