<div class="markdown_content"><p>Our machine is set up using persistent-retain variables which are entered into the PLC during start-up.<br/> We are very worried about losing them after a hardware or software fault.</p> <p>So we go into 'PLC-Browser' and 'SaveRetain' to a CF-card file.<br/> We can then read the file from PLC to PC using 'Read File from PLC', or write it back using 'Write file to PLC' and refresh variables using 'RestoreRetain'.<br/> All of this works very well!<br/> But it would be nice to be able to read the values of the file into our machine database.<br/> But we do not know how to read the persistent-variable values out of the file.<br/> Can anybody help ?</p></div>
