<div class="markdown_content"><p>Is it possible to map array element to a EtherCAT Slave variable. I am trying to communicate with a EtherCAT HMI to read the floating variable. So I need to convert them in codesys from udint to real using arrays and union. I am trying to do with array. But I can't able to map them in I/O Mapping to EtherCAT Slave. Is there anyway I can map the array element to the EtherCAT HMI Variable?.</p></div>
