<div class="markdown_content"><p>You can also use a pointer to an array of word and stick the high and low word in there and then have a pointer do dword with the address of the low word.<br/> And I think there are functions blocks in the OSCAT library for that or from some manufacturers e.g. Wago.</p> <p>Sent from my SM-G935F using Tapatalk</p></div>

<div class="markdown_content"><p>First of all I say I just started with codesys and although I love it I am very newbie.<br/> I have a doubt and managed to read modbus both ip and rtu. But the records I use are usually double records, now what I do is that I read them individually and put them together in a function that multiplies by 65536 the high part and the low part. Can you do this codesys only in some way ???</p> <p>Greetings, excuse my bad English.</p> <p>greetings and congratulations on the product and forum</p> <p>regards,</p></div>
