"Hello everyone,
I'm currently trying to establish a connection between TIA Portal and a PLC Siemens using Radmin VPN. I have configured the VPN connection successfully and can access other devices on the network, but I'm having trouble communicating with the PLC through TIA Portal.
I've assigned a static IP to the PLC and made sure it's on the same subnet as the virtual network created by Radmin VPN. However, I still can't detect the PLC in TIA Portal.
Has anyone encountered a similar issue or have any suggestions on how to troubleshoot this problem? Any help would be greatly appreciated.
Thank you!"
On all computers must be installed Radmin VPN. All of them must be logged into the desired network in the radmin vpn program itself. Then you will need to check port which uses software or application.
