Hi Willem, that would be great … and I wanted to say … probably not post that on this public list. I can forward that to some more protected Lists and we can hand that out to people that are part of the project only.

However, this makes things easier, I guess. We can just fire up a separate PLC4X OpenVPN server directly on our router and route both PLC/HMI. I can share the configs with you when finished?

Perhaps that would be something worth investigating? https://openvpn.net/cloud-vpn/pricing/ Chris From: Christofer Dutz <christofer.d...@c-ware.de> Date: Monday, 21.

Unfortunately, I should probably take the VPN documentation offline as this was the state when I was still at codecentric. I do have my own VPN equipment setup here, but all PLCs are now attached to my Fischertechnik factory and changes to the PLC programming could have mechanically fatal implications. So, I’m not giving out access to the public, like I did when there were just a bunch of PLCs hanging on a wall ;-) The other thing is that the factory is very bright, so I tend to turn it off and only turn it on if I’m working on it. Using lightbulbs and photo-resistors does have its disadvantages over laser light barriers. So, I guess we’d probably have to setup something new.

Now you bring hardware to the table I would like to offer our hardware to the project. I've seen a small VPN network which could be extended with the following hardware. - S7314-C PN/DP - TP700 Comfort Currently I do approach these devices over OpenVPN myself as they are mounted on our development wall in the office. If desired, we could extend it with a site-to-site connection?

I am sure Cesar, the author of the Subscription part of S7 will be able to help you. As a first suggestion, I think you can’t just subscribe to changes of any normal PLC areas. I do think this is a completely different set of fields with a different syntax. Chris From: Willem Remie <w.re...@remsol.nl> Date: Sunday, 20.
