Remote access to Siemens plcs through 3/4G

Hi,

We have a plant running with 4 Siemens 315-2DP.

At the moment I have set up a Westermo switch, in which we can connect through a VPN. In order for us to do this the company that owns the plant have to plug the ethernet cable into their main router, otherwise we are physically disconnected from Internet. It is their policy to do this for security purposes. They do not want to have a constant connection to Internet through their router.

I would like to do it differently. I would like to connect our plcs directly to Internet.

The plcs have Ethernet CP343-1 Lean cards in their racks.

Do you know if there is any device I can connect to the Siemens rack, which has a SIM card so that I can get online through 3/4G ?

I would like to monitor the plcs, and run a webbrowser on the Siemens panels that we have there.

Anyone who knows if this is possible ?

Thanks !

Phoenix Contact MGuard has a 3G router, not exactly simple to set up, but get in touch with your local Phoenix rep and they'll help you. Good Luck.

First, I would say that you shouldn't try to go around the plant's wishes. If they are uncomfortable having the machines connected to the internet, they might have a reason.

Second, cell modems work well in theory, but in practice, they often have bad coverage inside plants. At least here in the US, most factories are built like bomb shelters (actually, most of the old ones ARE bomb shelters), and you couldn't get a cell signal inside to save your life.

Third, if you're already using Siemens PLC's, you might want to ask your Siemens rep what options they have. I've seen them marketing cell modems here in the US. I assume they work with many countries' phone networks.

Give call to LMC, they have helped me out with similar requests in the past. But as mentioned above, I would not go against company policy..

Hei Orense,

You may wanna have a look at the Netbiter EC350, it has a feature called remote access and it will estblish a VPN tunnel to the Netbiter hardware (on site). One of the nice features is that you get 1Gb/month.
