Posted 30 Jul 2021 https://www.ewon.biz/products/cosy https://www.tosibox.com/product/lock500/ VPN is by far the easiest method. If you have a PC with Sysmac Studio installed, you can use Teamviewer. I haven't tried this but here is a link from MyOmron. https://www.myomron.com/modules/KB/file_d.php?id=743 Share this post Link to post Share on other sites
Posted 30 Jul 2021 (edited) Hi @IO_Rack We have regularly used the VPN to access PLCs for programming changes but I am confused how I can use the same method to connect to PLCs together? I'm guessing there is away of setting up port forwarding on both routers if I have a static IP at each side? What I am trying to do is basically send alarm data to a second PLC which is approximately 50Kms, and have this warn the operator and slow down the equipment.
