We can offer customers using our HMI screens remote access through TCP/IP ethernet allowing you to duplicate all your HMI screens easily on your smart phone/tablet. Full interaction or just monitoring options are possible for each individual HMI's...allowing you to police who can view and who can interact with the screens.
We can also supply and install RF modbus communications where serial/ethernet LAN is unavailable. Working ranges up to 2KM without a repeater is potentially possible and up to 8KM is potentially possible with a well placed repeater.
We are also actively looking into reliable 3G and 4G communication possibilities so watch this space.
