How to create a variable in the PLC and set its AT property on Omron NJ1400?

[ottobolyos]

Here’s a quote from README.md:

• FINS works with PLC Addresses. NJ and NX PLCs do NOT have direct addresses to addresses like DM or E0_, E1_.
  • In order to use C Series addresses in an N Series PLC, you will need to create a variable in the PLC and set its AT property. E.G. If you want to read and write 40 WDs from E0_9000 ~ E0_9039 then you need to add a TAG like this TAG_NAME ARRAY[0..39] Of WORD %E0_9000
    

How do I do this for Omron NJ1400?

At the moment, I am successfully connected to the PLC, however, I cannot get the data (there is no output to the debug console; I am trying to read global.ProductCount.Count1 address if that matters):

Thank you in advance! 🙏

Update

First I tried to hard-code the address value into th FINS read node, then there was no error. However, when I use msg.topic set to global.ProductCount.Count1 in the timestamp node, it now throws an error: address is not valid. I suspect it is related to the fact the AT property is not yet set.

I'm not 100% certain NJ 1400 supports fins access but if it does you MUST set at column with a valid address as shown in the readme.

Check the ethernet settings - look for "fins"
