Reach any machine. From anywhere.
Program, diagnose and support PLCs, HMIs and drives on site from your own desk. No site visit, no site VPN, no ports opened on the plant firewall.
Outgoing only
Nothing on the plant network is exposed to the internet.
Access you control
Every session is logged, and removing someone ends their access at once.
No changes to your PLCs
Machines keep their addresses and settings.
From your desk to the machine.
