<div class="markdown_content"><p>Hello Peter,</p> <p>I don't know if you can find a solution yet, but I'll post an answer here, because it might be useful for someone else.</p> <p>When a M function is called, the <span>[SMC_Interpolator]</span> block will indicate the function number at output <span>[wM]</span>, and then stop all movements and wait for <span>[bAckM]</span>.</p> <p>It is possible to send parameters using <span>[SMC_GetMParameters]</span> too (I didn't get to test this).</p> <p>According to DIN 66025, there are some fixed M-functions (like M30 = end program), but I did not find a definition in the codesys documentation. As far as I tested, the limit for function M would be 2^16.</p> <p>\o_</p></div>
