making a parameter file

rhikp — Wed, 25 Mar 2009 12:49:41 GMT

I am using the modbus example.vi to read parameters over modbus. I want to modify this file to read multiple parameters from, for example a spreadsheet. Is there any tutorials/examples i can use to do this? or can anyone give me advice?

My absolute favorite method for reading parameters is to use a windows configuration (.ini) file. There are lots of examples of this as well as Excel. Go to Help-->Find Examples

Thanks Matt for the reply. was cosidring using a .csv or ini file but i am really confused on how to implement this with my modbus example. I am really new to labview and struggle. I want to make a table that contains parameter address, address type, etc and feed these values into the bundle in my vi. Is this possible and if so how do I do it? I can attach part of the parameter list if it would be of help?

There's a bunch of vi's for configuration files -- all ready made for you. They really do make your life easier.

If you need help understanding them, look through the examples. Start by going to help and typing configuration file or ini file. If that doesn't work, let me know.

thank you for the link. It seems to be of use however i cannot open the .vi files as I am using labview 8.0 and the files are created in labview 8.2. Is it possible to get these fgiles in my version?

If you follow the link to: http://zone.ni.com/devzone/cda/epd/p/id/4776 you will see a zip file that is compatable with LabVIEW 7.1. You can open that with LabVIEW 8.0 and compile for version 8.0 using Tools>>Mass Compile.

I got those files to work. I attached this to the modbus example vi and i can use it to read one parameter. How can i modify it to read multiple parameters? I want to be able to further down the line add additional parameters to the config file and not have to modify the labview code. any suggestions?

thanks again for the links!!!

Use additional Read Key vi's. If that isn't enough, post your vi and the ini file.

(Of course, you'll also have to add matching lines to your .ini file)
