<div class="markdown_content"><p>Hi,<br/> what about using a SQL database for read/write instead of importing the complete arrays?</p> <p>Have a look in the store and search for "SQL".</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> 87skier</p> <p>Hello,</p> <p>I am writing a PLC program to manipulate large 2d arrays, about 100x100. I need to import the values (mostly of the form 1.234e5) into my program at startup but not sure of the best way to do it. I have them stored in CSV files and can alter them to fit the needs of the PLC.</p> <p>The system needs to be reasonably flexible. Mainly, it needs to be changeable without having to manually copy in thousands of lines of a multi-dimensional array.</p> <p>Any suggestions here?</p> <p>Thank you</p></div>
