Related ISSUE #33

Hello @PLCHome, thank you! Sorry for the delayed answer - i am rarely on the site of my customer to test.

I tested it and get the error "is nan is not defined."

Also i creadet my own package "node-red-contrib-ads-read", which works fine. I will delete it as soon as your package ist working on our installation.

In picture you can see my flow.

Unfortunately, I can't see why. Can you post the flow as json.

Hi,

I have this same problem. There´s the flow below.

My problem is that I have so old PLC that it doesn´t allow variable names to fetch or send.

Did someone ever managed to solve this issue? I have the same "is nan is not defined." issue when reading using index. When I read using the varname it works fine.

I managed to make it run. I found the bug and I'll submit a PR.
