<div class="markdown_content"><p><em>Originally created by:</em> Nicolai_Hanssing</p> <p>Hi,</p> <p>I am currently working with a PLC-Open implementation that does not support hardware limit-switches in the Target.</p> <p>Is there anyway that I can map/update the limit-switch structure in user application-space?<br/> Paramenter #1206 AXIS_REF.bHWLimitEnable must ofcourse be true, but where and how it the pointer-mapping and/or update for these inputs done?</p> <p>I need this on a modulo-configered axis, which is actually a linear axis, but needs modulo-positioning due to absolute position excceding 2^31 increments which is not handled correctly in PLC-Open Softmotion.</p> <p>Right now I have my own handling implemented, but I would like to also pass limit-switches to the Softmotion-library to have 'belt &amp; suspenders' solution.</p> <p>Regards<br/> Nicolai Hanssing</p></div>
