We Need Your Help
24 Jan, 2012 | Written by Rosemount Analytical | under Uncategorized
Folks, this is Jim Gray, and in this blog I want you to do the talking.
We are in the investigation mode for updating our intrinsically safe two wire analytical transmitter, and we would greatly appreciate your input. What features are important to you and your day-to-day operation? Here are some areas you might consider:
- What could be done with the local operator interface to make it easier to calibrate and configure the transmitter and access diagnostic messages?
- How much information would be useful at the Local Operator Interface (LOI)?
- How much do you rely on a hard copy manual?
- Would it make it easier to have this information available using the LOI?
- How could transmitter installation and sensor replacement be made easier?
- What digital protocols are important?
- Do you access transmitters using the device description or FDT/DTM?
- Are there any features of these protocols that are not presently being implemented, that you feel are important, like control in the field in the case of FOUNDATION Fieldbus
Your thoughts on these or any other aspects of installing and maintaining analytical transmitters would be very much appreciated. If you include the rationale behind your ideas, it might help us find a novel solution to fulfilling your needs. It might also help you win a $100 Best Buy gift card for providing the best feedback!

Hello,
I am a new tech at a 600MW combined cycle power plant for Calpine Corp. I have several issues facing me with 6095 multi variable transmitters with tri-loops, and several 3051C transmitters on our HRSG boiler drum levels. I would hope for some articles covering basic transmitter operation and calibration using field communicators 375, and 475.
Thank you for your time,
Anthony Merlonghi

This is relating to the feedback request from Jim Gray.
◦What could be done with the local operator interface to make it easier to calibrate and configure the transmitter and access diagnostic messages?
**Make an active keypad that will allow quick selection of diagnostic messages like the light sensitive keys on the OCX88
◦How much information would be useful at the Local Operator Interface (LOI)?
**Diagnostic and selectable values to appear on the lower level of the display like the 1056/1066 has.
◦How much do you rely on a hard copy manual?
**Little to none
◦Would it make it easier to have this information available using the LOI?
**The LOI is the first place that people look for diagnostics so I think this is of great value.
◦How could transmitter installation and sensor replacement be made easier?
**Smart capable. If we can work out a way to connect competitive sensors it would make it easier to replace and promote diagnostics that they don’t have.
◦What digital protocols are important?
** FF and Profibus if possible.
◦Do you access transmitters using the device description or FDT/DTM?
**Most are device description because it is simpler to use.
◦Are there any features of these protocols that are not presently being implemented, that you feel are important, like control in the field in the case of FOUNDATION Fieldbus
** I think as soon as you add the protocol it should be standard. I think to promote the power of FF we need to make it more common place.

◦What could be done with the local operator interface to make it easier to calibrate and configure the transmitter and access diagnostic messages?
.- In the oxymitter 4000 when you are doing the calibration you cannot see how much oxygen is reading the analyzer, also It would be useful can see the range in scale mode I mean a small bar showing the range and how much the analyzer is reading.
◦How much information would be useful at the Local Operator Interface (LOI)?
.- The range in graphical mode and numeric
◦How much do you rely on a hard copy manual?
.- I always go to field with the product manual when there is some trouble
◦Would it make it easier to have this information available using the LOI?
.- I think that the LOI is not the right place in order to see the manual, It must be keep in paper. The LOI is very useful in order to see how is working the analyzer.
◦How could transmitter installation and sensor replacement be made easier?
.- We have a OXT4000 installed in our CCR and when we need to change it this is a nightmare for me, I think that you need urgently improve the Isolation valve system, also you must recommend test the oxt4000 before got installed in the process, I always install it like the is installed in a furnace, and I put some patron gases in order to see how is working the analyzer. some years ago I installed a brand new OXT and this did not work.
◦What digital protocols are important?
We only use the 4-20mA, lol
◦Do you access transmitters using the device description or FDT/DTM?
I use DD
◦Are there any features of these protocols that are not presently being implemented, that you feel are important, like control in the field in the case of FOUNDATION Fieldbus
No idea.

What could be done with the local operator interface to make it easier to calibrate and configure the transmitter and access diagnostic messages?
>>>Use large NAMUR NE 107 compliant diagnostics symbols/icons for Maintenance Required, Out of Specification, Check Function, and Failure
Backlit display, on two-wire transmitters, at least on FF which can draw more current
Make sure EDDL includes wizards for standardization/calibration etc. Make sure diagnostics have conditional images for illustration and help text for guidance.
If it has buttons or equivalent (remote control or LOI), consider a short “beeping” when buttons are pressed. Longer beep on errors
How much information would be useful at the Local Operator Interface (LOI)?
>>>Diagnostics to display the cure not long list of symptoms
How much do you rely on a hard copy manual?
>>>It should be intuitive. No manual required for daily operations
Would it make it easier to have this information available using the LOI?
>>>No. Maybe have context sensitive help. If I dwell “too long” on a screen without making the next entry, context sensitive help pops up automatically. Or have a help button.
How could transmitter installation and sensor replacement be made easier?
>>>Reduce number of wires to connect the sensors and eliminate need for special multi-core cable, maybe just two or four cores, regular cable. Maybe the whole transmitter with all signal conditioning and A/D inside a transmitter “head” on the sensor. The regular housing is just as a display and LOI – similar to 3051S-ERS or Raptor 2430 display
What digital protocols are important?
>>>PROFIBUS-PA is common in the water industry. FF is common in oil & gas.
Do you access transmitters using the device description or FDT/DTM?
>>>EDDL. Use eDTM in case host only supports FDT. Make sure EDDL includes wizards for standardization/calibration etc. Make sure diagnostics have conditional images for illustration and help text for guidance.
Are there any features of these protocols that are not presently being implemented, that you feel are important, like control in the field in the case of FOUNDATION Fieldbus
>>>NE 107 “Field Diagnostics”

Hi, We are reviewing the submissions. Thanks for taking the time to respond. Jim will get back to you later this week with any questions/comments and to announce a winner.

Anthony Merlonghi – here is the answer to your question:
There is a support group that is specifically set up to answer technical questions on these devices. Their number is 1 800 999 9307. I would suggest that is a good starting place.
For the 3051C, he can also go to:
a) The Rosemount Quick Installation Guides (QIGs) on their site. These are easy to read and have a good section on how to hook up the 375 / 475 and configure 3051 Devices,
http://www2.emersonprocess.com/siteadmincenter/PM%20Rosemount%20Documents/00825-0100-4001.pdf
b) The “475 in Action” Videos on the fieldcommunicator.com site, http://www2.emersonprocess.com/en-US/brands/Field-Communicator/Pages/ApplicationVideos.aspx
The reference to the 6095 had us stumped, but I spoke to the support group at the number above and we think it is a typo; he probably means the 3095. Again, the 800 number is a great starting place.
