<div class="markdown_content"><p>The word output is sometimes strangely formatted.<br/> but in general the conversion like ndzied tells is working,<br/> Inputs are sometimes shifted so will need special attention before scaling.</p> <p>Have a look at the oscat library with many functions for this.</p></div>

<div class="markdown_content"><p>The standard includes a REAL_TO_WORD() function. You only need to check with your hardware documentation to see what numerical value corresponds to the real world voltage or current signals.</p> <p>Usually you perform a scaling function first to create the number you need to send to the analog output, for instance, a 12 bit analog output would likely take numbers from 0 to 4095.</p></div>

<div class="markdown_content"><p>Most of the libraries for analog processing ( 0-10V, 4-20mA…) are using “real” as output. For an analog output module you need a datatype “word”. How can I easily convert real to word?<br/> Does a library exist with a function REAL_TO_WORD function?</p> <p>I think it must be also possible with pointers but have anyone experience with it and/or having a example program?</p></div>
