<div class="markdown_content"><p><em>Originally created by:</em> scott_cunningham</p> <p>One possibility (assuming your IO hardware is based on BOOL assignments) using ST language:</p> <p>You may want to create a FB and use methods instead of a program with actions.</p> <p>This is just one example. Check your hardware mapping - I have one hardware I work with (4 in / 4 out) that uses one BYTE to control the INs and one BTYE to control the OUTs - which would be super easy to turn all on at once (BYTE = 255). But that is not the norm.</p> <p>I think trying to do this with LD would be a bit tedious.</p></div>

<div class="markdown_content"><p>I'm trying to turn on any combination of 128 PLC outputs using 1 variable. I've never done this before so I wanted to see if any one has any suggestions. I would appreciate your input. </p></div>
