Title: Basic Data Logger 2
Post by: bkane on February 28, 2018, 02:34:04 PM

Hello

I am attempting to use the data logger 2 to write multiple values to a .csv file. I read in a previous forum post that the data can be separated into different columns using the prefix function. Does this mean I will have to use multiple data loggers for multiple outputs to put them in different columns? Or is there a way to do this using the collection function on the basic data logger 2? Also, sorry for the loaded post, but is there a way to create new .csv files every run? Or will the data logger overwrite the previous file every run?

Thanks

The BasicDatalogger2 will log the value of the items listed in PLCAddressValueItems to the log file as comma separated values.

I was just going to reply to myself that I figured out what I was doing wrong. Thanks though.

But I still need to figure out how to stop writing to one .csv file and to create another one. For example, I want the logger to write to a different file every 24 hours or when I click a button. Is this at all possible?

This is the way i have done that before, just take the "HH-mm" out of the code to make it store to a new file everyday.

Note that this time is coming from the PC this program is running on.

Code: [Select]

    Private Sub BasicDataLogger1_DataChanged(sender As Object, e As Drivers.Common.PlcComEventArgs) Handles BasicDataLogger1.DataChanged

        Dim logstamp As String = ".log"
        Dim timeStamp As String = DateTime.Now.ToString("yy-MM-dd-hh-mm")
        Dim Stamp As String

        Stamp = timeStamp & logstamp

        BasicDataLogger2.FileName = Stamp

    End Sub
