connecte to HMI/PLC over internet and programme
Posted: Wed Oct 17, 2018 11:01 am
Hello all,
I have a scenario where I need to programme and configure industrial devices like PLC, HMI and many more devices on remote site(manufacturing unit). this not the only case, this type of configurations I need to do very frequently on various manufacturing locations, I want to install small RAS PI box with all configurations read and than I must be able to connected to any device when needed.
but in this situation conditions are
1. no one on remote site is available who can connect their PLC, HMI to a laptop.
2. no port forwarding and static ip need on remote site(manufacturing location).
3. no human interaction to connect to vpn.
But, yes internet connectivity is available.
I need bi directional traffic where office computers and access that PLC and HMI as like they connected in Local Lan and can work on that.
What I was thinking as part of this solution is as below,
possibility-1
1. configure softether vpn server on one of my PC at my office(it can possibly be on cloud also, if needed).
2. on remote site, use RAS PI computer installed with soft-ether client(this box is connected to internet and also to PLC, HMI) and connect that in bridge mode to soft ether vpn server configured at office.
3. at office technical person will connect to the same soft ether vpn server in bridge mode.
now both the client can communicate with each other in bi directional mode.
possibility-2
1. configure softether vpn server on one of my PC at my office(it can possibly be on cloud also, if needed).
2. on remote site put dd wrt router/open vpn supported router and connect it in bridge to soft server.
3. at office technical person will connect to the same soft ether vpn server in bridge mode.
trying to RAS PI box with router.
need your input on both the possible solutions I thought.
Guide me if anyone has worked on Ras PI with soft ether.
I am new here and first time doing this type of configurations, need your suggestions that it can work or not as per my scenario.
