how can I do to visualise my modbus registers on a chart?

[BlueEyed]

hello people, i have a labview project, and i'm trying to visualise the data in my registers with a chart but i can not link the chart to the modbus data out.

i will attach my project, so u can see what is my problem.Also i have to put this data that i'm reading from my Modbus instrument into some kind of report and to read it with Microsoft Excel, is that posible? can I extract and read them with excel?

Thank you in advance and a good day to you all.

- You need to convert your array into a cluster otherwise if you feed an array to the waveform chart, it treats it as a single plot with multiple points. You just have to use the Array to Cluster node (Programming -> Cluster...).

- Yes, this is possible. Search through the forums and the Example Finder. If you are not able to find anything concrete, post back.

I have tried to convert it but no result:(

Can i change that type of value from the chart: double [64-bit real (~15 digit precision)] ?

You need to understand what you are doing. Doesn't the cluster that's output from the VI have a Data array element? Isn't that what you want to see on the waveform chart?

Well, if you need the data array from the cluster, then you need to use the Unbundle function. After that, you can use the Array to Cluster node to view the data on the Waveform Chart.

ok i think this is it.Thank you verry much, now i can see the data on the chart, but how can i do to make those excel reports?

my project has to monitor some registers, and i have to put the results into some kind of reports.  so can you teach me how to do that?

Try searching through the forums and having a look in the File I/O palette. There is a Write to Spreadsheet File VI that could help you create a .csv file which can be opened in Excel.
