As udshred points out, you need to decode the model number which is stamped on the nameplate, which Rosemount refers to as ordering information in their manuals. The digit after the 3051CD is the range code, as shown in the screen shot from the manual. If you power it up and check it via...

The older OPC DA reported data when the data moved outside a noise band around the last reported point; data within the noise was not reported. I missed that webinar on the basics of OPC UA, but I'll assume OPC UA does the same thing as OPC DA. Your explanation does not mention missing data...

Use the on-line Modbus poll user manual at the link above. Scroll down to section 5 Read/Write Definition where it shows the set-up parameters and right at the top is the Slave ID setting.

In other HMI products, an X-Y plot is produced by specifying one array for the X axis and another array for the Y axis. Historically, it was called an X-Y plot, as opposed to a Y-t trend.

There is no means of assigning a slave ID in Modbus Poll because Modbus Poll is a Modbus Master/Client program. on-line Modbus poll user manual Modbus master/client software applications NEVER have a slave ID because they are not slaves. You need a Modbus Slave application if you need to...

I'm on page one, and you're page 8. The typical application for DRS is hydrostatic liquid level measurement, where the slave goes up top and measures the vapor space pressure (in your case a vacuum) and the master is mounted down low and measures the combined vessel pressure and hydrostatic...

That's gotta be a DCS because the graph has no units. I flunk students who fail to use use units. 74.98 what? 82.93 what?

Do you possibly mean 'interlocks' or 'permissives', instead of 'inhibitions'?

Not to your point, but a personal anecdote about a dead weight tester as perceived by an electronics guy. My dad got his ham radio operator license at age 9, in 1929 and built most of his own ham equipment from scratch. In his electrical engineering program in college, he was in a work-study...

I have no idea what the image that you posted means. What are those numbers and where do they come from? What did you expect the numbers to be and how do the numbers vary from what you expected?

The register addressing for Micromotion appears to be consolidated into a single reference manual at this link: https://i.postimg.cc/yYV1LdNh/Micromotion-register-list-mixes-Holding-and-Input-Registers.jpg Unfortunately, the manual is arranged by the values' number format - Floating point...

I didn't even know Badger had a Coriolis line, so I have no experience, but before I buy stuff I at least skim read through the user manual because that's what I'd have to rely on to make the thing work. Here's some of the things the CRL-UM-00038-EN-10 user manual revealed that I noted. -...

I somehow overlooked this article on troubleshooting FF. https://control.com/textbook/foundation-fieldbus-instrumentation/h1-ff-segment-troubleshooting/ The article mentions Relcom who manufactures Fieldbus testers. Relcom products I worked on uP boards in the late 1970's and can say that...

How informative it was to read your post - with all the things you've done to attempt to resolve the FF comm problem. There might be someone out there with the same positioners that will show up and comment, but if the situation had been solved, one would think that word would have traveled...

Have you contacted Honeywell's service group? It's a paid service, but I believe that there are still one or two service guys around who worked on S9000's.

Have you tried all the start register values on either side of the target? (3)0019, (3)0020 and (3)0021 (3)0022 Reading only 2 registers? Can you do a single shot poll rather than sequential polls or the polling way down to make sure the slave (or the master) isn't choking. I can't...

Which answer here do you think fits the test question best? https://www.allinterview.com/showanswers/143291/use-of-glycol-filling-in-seal-pot-or-condensate-pot-in-instrument-impluse-line.html

With regards to serial communication Both ends need to have the same physical hardware bus layer. RS-485 is one such physical hardware bus layer that allows for point-to-point communications with suitable protocol and applications implemnentation. Both ends need firmware software to regulate...

I don't get why any engineered product would ground an RTD lead. The beauty of an RTD is that it be inherently isolated, because the measurement relies on a constant current 'excitation' source so that the resulting voltage drop can be 'read'. The resistance wire, which is wound element...

1. Input vs Holding Registers The Modbus documentation has some factual errors with regards to Input vs Holding Registers. Their use of the expression 40022 for a register address (page 8) is incorrect because the leading numeral 4 in the expression is a Modbus spec/convention that defines a...
