I am trying to create a function block to be able to write the Object Parameters in x70 (eg. H1_limit)

The problem I am running into is I bring the Object name in as string and then try to add what value I want to read and join them together. I get an error because VALUE is a real and TagVal is a string. Is there a way to have the ST recognize this tagVal as an object and read the Value I am trying to get. Below is the ST. 

Thanks

if TAG <>'' Then (*Tag = PIO_SP474_AI1*)

     tagVal := (CONCAT_STR(tag,'.H1_LIMIT'));

      VALUE := tagVal;
else

      Value := -999.9;

end_if;

Hi,

I've just recently started using the RemoteConnect software, so might be barking up the wrong tree, but from what I can see, if you need to specify the Object name via a string, then you might need to use the "OBJ_NameToID" function to get the ID, then you can use the returned ID into the "OBJ_WriteField" function to update the attribute of interest.

Good luck,
