Hi Cesar, Thanks for your response and willingness to help.
I'm using the example provided `HelloPlc4xSubscription --connection-string s7://10.15.72.50 --tag-addresses %DB1:0:WORD` Currently the following setup is installed at our office; - CPU 314C-2 PN/DP (10.15.72.50) - CP 343-1 Lean (10.15.72.51) - TP700 Comfort (10.15.72.52) We are working to setup VPN such that we can grant you access. I will send the configuration separately once finished. Chris could you please add me to the Slack channel as well?

I will test it with a S7-400 CPU, so I will need the model and firmware version of your CPU in order to keep track. Grateful for your support.
