Need some direction on creating a report

I need to create a report that will display the lowest value that a tag registered throughout an entire day, along with the time that occurred. On top of that I need to display this information for the entire month.

I really do not know how to approach this at the moment.

I thought about using the standard report type since I believe it dumps all the available data into the report, and then possibly using a macro within the excel spreadsheet to pick out the lowest value from each day, grabbing the date/time stamp as well. I am not entirely sure how to do this, I do know how to view the macro thanks to the Developers guide.

Then I need a single excel spreadsheet for each month displaying the lowest value and time from each day. So again maybe its possible to append the report that is ran each day into the previous days report. 1st of the month starts a new report. Possible, I don't know.

Is there a way to view the SRC files for the various report types available by default in VTSCADA?

Thanks!

So I've been playing with the creating my own report type following the instructions in help files "Common Features of a Report Module". I've edited the example to provide the lowest value over a 24 hour period. The time column shows 0 though. I also want to poll the time of the lowest value and display it in place of the current time column.

The instructions say that you can retrieve more than one mode in a single GetLog statement and to do that to pass an array of values in as the mode parameter. I got as far as making Mode an array.

Hopefully someone will be able to help me with this.

I edited the example and figured out how to do the arrays for the mode. Everything complies and a report is created but the data fields are blank.

Well I eventually figured out how to make this work.

I had to use separate GetLog instructions to get both the lowest value and the time that the lowest value occurred. I just could not get it to work with using a single GetLog instruction and using arrays for the Mode and Name fields. Followed a few examples but could not get it to work. I could get it to poll for a single date, but would not work for a group of dates like an entire month.

This is the working code. You can select multiple tags and it will create additional columns showing the lowest value and the date-time the lowest value occurred.
