But if you truly are getting that precise I doubt it then you probably want to send your data in 32 bit long integer format, scaled by a scale factor. Will your instrument be able to acutally measure that accurately? The number of significant digits you show is almost ridiculous. Can some one help us on this? Scroll to continue with content. Some of you have must have had some experience on handling this king of values. We have floating point values like I like to know which is the best method, function code to do this. We are designing a instrument to measure voltage and current. For a better experience, please enable JavaScript in your browser before proceeding. Was this information helpful? Not Helpful.Latest Projects Education. To use a snippet, right-click the image, save it to your computer, and drag the file onto your LabVIEW diagram. The least significant bits are stored in the first register. Figure 1 below shows how floating point numbers are defined using IEEE standard.

#Modbus float format how to

Modbus does not declare a standard how to represent floating point numbers, so it is possible that a device handles floating point numbers differently than LabVIEW. Currently the most significant bytes are placed in the first register, how can I swap the bytes for my application? Solution Since Modbus uses bit registers to hold values, bit floating point numbers must split between two registers. This solution might also apply to other similar products or applications. Reported In shows products that are verified to work for the solution described in this article. This content is not available in your preferred language.

#Modbus float format manuals

Since Elmer manuals seem to be very hard to find on the web, could yopu [please give us more infoprmation about their claim to use bit registers over Modbus?

How to Swap Registers for Modbus Floating Point Values Or, in other cases, the REAL bit value was multiplied by a certain exponent of 10, transmitted as a bit integer that you had to divide by the same original multiplier. If I poll a 32b register with a value ofthe node-red poll send me an array with.

#Modbus float format update

Update 3 : maybe it will help you, but the weird thing about my plc is that the right value is in the array when dealing with 32b registers. Why the others are changing? A real mystery for me. Assuming this is in a recent version of node-red PPz which version is it? PPz in the functions use node. Try to remember the asynchronous nature of node-red and how object references work in JavaScript. How is it possible? Writy fnp0 javax net ssl sslhandshakeexception pkix path building I really don't know why those 2 lines are needed, but without: no results. Stranger, with 2 polls with the same code, I obtain 2 sets of variable values The value set in my modbus register is Ok, I'm a real newbie and I added what I found around here. It seems that for me the code is not that difficult However, very strange to me, the result varies with every poll even the data in the register is fixed for my test. See this thread read it all there are some pointers in there that might help. That's the reason I set the value of Easier to remember. When I debug in node-red, I obtain an array: but I'm stuck to convert this to a readable precise value of I have no probs with int16 registers because they are 16bits obviously but need to find a function to convert negative values to readable ones I found here a function but the result seems weird imprecise.
