Siemens tag address syntax in OPC Item Path

Ignition
1

OPC Item Path - ns=1;s=[Packer]DB20,DBW100 is not getting the tag data from the Siemens S7-1500.
Device Connections - The Siemens S7 shows Connected
Siemens Rack 0, slot 0
S7 Tag address - %DB20.DBW100 (INT)
Tried Data types W, I, D, DI, and DBW

more system info:
the PLC IP address is on a different subnet from the the Ignition server so the connection is thru an Edge Router X.
Ignition version 7.9
The Ignition driver adds the port 102
Port forwarding in the router does not include the :102
Tag Quality shows Bad or Error Configuration

thank you for solution suggestions

no responses?!?!?!
Is it the router config, PLC comm setup or the Ignition S7driver?

I would guess this should be ns=1;s=[Packer]DB20,W10, based on the format described in IA's manual.

BTW:

This is a volunteer forum, not official IA support. If you want an assured response, open a support ticket.

make sure your Siemens PLC has the box checked for Activate OPC UA Client!

? Are you not using IA's own driver? (That's what your OPC Item Path looks like.)

The machine builder did not check the Activate OPC UA Client checkbox in TIA Portal. I discovered it after installing trial version of TIA. Been troubleshooting this for weeks. Nobody here knew enough about Ignition and Siemens. Thanks Phil, Phil

You may not want, what appears to be a phone number available to the public. So might want to edit the post and remove that.

One of the reasons I don't reply via email.
