We're in love with Ignition! Great work, However, we miss a straightforward way to create JSON from OPC/memory tags. [Where: key = tag_name and value = value] We use JSON to connect to our MES. A flat UDT is used, which we'll iterate over.

Presumably, you have the names (as tagpaths) in list form. It is a one-liner to get the corresponding values. It is another one-liner to make a key-value dictionary. Like so: tagValues = [qv.value for qv in system.readBlocking(tagPaths)] tagDict = dict(zip([path.split('/')[-1] for path in tagPath…

It's not every day you get to fix something from Phil ! tagValues = [qv.value for qv in system.tag.readBlocking(tagPaths)] tagDict = dict(zip([path.split('/')[-1] for path in tagPaths], tagValues)) Fixed call to system.tag.readBlocking and missing parenthesis at the end.

You can also right click on a tag or folder and select "Copy JSON" and paste that into a text editor. Export works the same way. Depending on your situation either method may be ideal.
