<div class="markdown_content"><p>Actually, I learned today - when right clicking on the very top of the project tree, there is a "edit IO mappings" command that gives csv import/export to all mappings.</p></div>

<div class="markdown_content"><p>Is there a way do define the Modbus slave mappings in , and import them from, say MS Excel?</p> <p>If I have 400 objects with a few words each, like command mask word and some parameters, then what if I want to expand or modify my data set at a later time? Seems like a lot of work to edit the mapping table manually.<br/> Is there a way to define the mappings in StructuredText code programatically?<br/> It tried some "REFERENCE TO" juggeling, but that was not allowed.<br/> The Holding Registers must be writable from code so it does not really help to define a seperate array and simply mirror from that to code variables either, IMHO.</p> <p>Any hints?</p></div>
