Hello once again! I have a new one. My customer wants about 100 tags to be recorded into a .csv file, every hour, once each day. I have already set up the tag historian into MariaDB. I also have the reporting module, and logically thought that was the way to go. My issues are, I can't put the volume of tags onto a report table (or can i?). I set up the report DataSource with all the tags and unique key aliases, but I am struggling with "Table" or "Simple Table" components in the designer. I can add columns, but 100? Is there another way, other than the reporting module, or is there another approach WITH the reporting module? I am so very close to having automated .csv logged data. I ran a small data-set as a test with the report module, and the scheduling/saving to file works perfect. Thanks, Tim ---

Don't use the reporting module for this, unless you need graphics to go with the data. If you are aiming for just straight CSV data export, use a gateway scheduled script, and in there make a call to [`system.tag.queryTagHistory`](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-tag/system-tag-queryTagHistory) to pull the data for all the tags that you need. Then, convert the returned dataset to a csv using [`system.dataset.exportCSV`](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-dataset/system-dataset-exportCSV). For best results, create a [project library script](https://www.docs.inductiveautomation.com/docs/8.1/platform/scripting/scripting-in-ignition/project-library#add-a-script), and define the tags to read, as well as all the logic to fetch/convert and export in a function in this library, and call that function from the scheduled gateway script. ---

Hi Ryan, thanks for your response. It looks like there is a steep learning curve for this task. I hoped for something easier to follow. I might just use the report and break the data into smaller chunks, as my customer is one of those do it yesterday types. Maybe I can figure out the scripting after a while. ---

It really isn't too bad going with Ryan's approach both of the functions are well documented, with examples. ---

Honestly, everything in Ignition is a steeper than normal learning curve for me. But there are enough resources from tutorials, docs, forum posts, expert members, that a little trial and error and a little time, you will learn another skill and have a new example for your tool kit of solutions. Then those compound and it gets easier next time. ---

I understand that, and I will be hopefully getting a second project, where I can refine things I have learned into simpler tasks, such as this one. I will get my three log files working neatly, using the reporting module. I don't need to see the data as a PDF, just a .csv I will also create a handful of actual reports. Once the customer is happy, I will have time to learn the script approach, for my next project! Thanks for all your responses. I am half way done with datalog files! Tim
