<div class="markdown_content"><p>Thanks I-Campbell, your explanation helped me to understand an alias assignment isn't what I had figured out.<br/> I thought the alias could be assigned to the array elements, not to the array itself.<br/> Is this possible in anyway though? (assigning alias to array elements)</p></div>

<div class="markdown_content"><p>Alias means "another name for".<br/> Alias in CODESYS is a user defined data type (DUT).<br/> So if you make ThirtyTwoBytes an Alias of ARRAY <span>[0..31]</span> OF BYTE, you can declare myVar : ThirtyTwoBytes; or myVar1 : ARRAY <span>[0..31]</span> OF BYTE; and they'll be the same data type.</p> <p>I know another programming software where you have alias variables, but in CODESYS you have alias types.</p></div>

<div class="markdown_content"><p>Hi everybody,<br/> The Codesys online help isn't helping me too much to understand what an "Alias" is.<br/> Could someone perhaps show me a little example of an implementation of it?<br/> Particularly it interests me concerning arrays...<br/> Thanks in advance,<br/> Rob</p> <p><img alt="IMG: Capture1.PNG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4972"/></p></div>
