Hi all, I am trying to connect to some existing S7-300 via an existing SIMATIC NET OPC UA server using the Ignition OPC UA client. I am following this guide [Siemens S7-300/SIMATIC NET OPC Addressing in Ignition | DMC, Inc.](https://www.dmcinfo.com/latest-thinking/blog/id/10192/siemens-s7-300simatic-net-opc-addressing-in-ignition) and it has worked for all of the data types but I am not sure how to address a string data type. Anyone have experience with this? ---

Doesn't the SIMATIC NET OPC UA server expose tags via browsing using their symbolic names? ---

Yes that can be enabled but unfortunately this old PLC is using symbolic names with "." and can't be exposed so I have to use the direct addressing method like in the article.
