Access Datalogging

[sopenco]

Maybe there is already a feature I can't find in Advanced HMI to do this, and if I'm missing it pardon me for posting.  I think it would be awesome if there were a module that allowed a VB-idiot like myself to just drop in tags or addresses with labels and a log interval and have the HMI update an MS Access file periodically.  I'm sure it's been done by somebody, and it's probably not too difficult for a person who actually knows VB.  It would certainly be nice to be able to get away from FTView SE HMI's!!!!  Cheers, and keep up the terrific project development!

Database logging is unfortunately one of the most complicated tasks when doing in VB.NET. It's not something that can be explained in a single post, but you can look at the Entity Framework for .NET to give you an idea of where to start. It is the .NET way of interfacing to a database:

However, there is a BasicDataLogger component currently in testing that logs to text files. Next to follow will be an AdvancedDataLogger that will log to a database table.

Hey, I appreciate your reply and suggestions!  I'm surprised to hear the datalogging from over .NET is so difficult - you would think Microsoft would make it easier for their products to communicate with one another.  I think tht'll be just one more reason for me to stick to programming PLC's and leave the PC stuff to the PRO's!

I do have a SimpleDataLogger component that is also in testing. It simply connects to a single register and can be set to write the data to a text file either on a time interval or on change of data.

Hi Dusy, can you share that?
