TIA Portal v13 download to TP700

I am currently trying to download an updated program to a Siemens TP700 using TIA portal v13. I am trying to do this through a VPN connection from my office to a job site. The TP700 does not show up as an accessible device, although I can ping it. I originally downloaded the program while I was onsite, but now need to make an update. I have confirmed that the correct port numbers are open in the VPN. I have been able to update an older version HMI panel using WinCC flex 2008 sp3 over this same VPN connection. Any suggestions as to what the issue may be?

You need to make sure you are downloading via Ethernet, not via Profinet (PN/IE). This setting needs to match in the control panel of the TP700 and the download window of WinCC.

The PN service is great for downloading on the local network, and especially for the initial setup of equipment. It is capable of searching the HW on the local network, and identifying compatible equipment there. You have the option to flash LED's on the equipment to ensure that you have selected the correct equipment. However, the downside is that it can only search or download to the LOCAL network. Profinet is not a routable protocol, because it operates at layer 2 instead of layer 3 of the network. Most VPN systems only allow for Layer 3 access.

The Ethernet download method, however, uses standard TCP/IP and can be routed to a distant system though a VPN. The downside is that you need to know the exact IP address of the target panel. Once the system is set up the first time, this is usully true. Everything should match what you have configured in the project.

I usually use the PN/IE downloads as I am first commissioning a cell, and then I switch to the Ethernet driver if I expect to do any remote commissioning later on.

Thanks for the feedback I will give that a try

Deselect the "show compatible devices" in the transfer dialog.

Thanks for the replies, using the suggestions I have been able to connect to and update the TP700's
