<div class="markdown_content"><p>Hi<br/> A SINT is a short (signed) integer. It is already only 1 byte - so you should have no problem casting it to a byte like so: bMyByte := TO_BYTE(sintMyShortInt);<br/> If you have a regular INT you want to put in 2 bytes - there are a lot of ways you can do this. A Union is certainly one of them. You could have a union with 2 memebers: An array of 2 bytes as one member, and an integer value as another member.</p> <p>Another way would be to look at MEMCPY to put the value into your CAN-message.<br/> .. or create a function to take your input value as input, and giving you 2 individual bytes as output. This could be handy if you need to change the byte-order.</p> <p>Integer data types:<br/> <a href="https://help.codesys.com/webapp/_cds_datatype_integer;product=codesys;version=3.5.17.0" rel="nofollow">https://help.codesys.com/webapp/_cds_datatype_integer;product=codesys;version=3.5.17.0</a></p> <p>-Bjarne</p></div>

<div class="markdown_content"><p>Hi everyone,<br/> I have been doing a project where I have to send CAN messages from WAGO plc pf200 in BYtes. The signed integer needs to be unpacked into two bytes. so far I have tried Union but that has not worked with me</p></div>
