Full Control From Anywhere
Every ControlByWeb smart relay is powered by a built-in web server. You can set up, monitor, and manage your relay using a standard web browser. Relays are also capable of sending email notifications and logging data, giving you access to the information you need, where and when you need it.
No-Code Programming
Many IIoT devices require extensive programming knowledge to set up and manage. ControlByWeb PLCs allow you to create custom “tasks” using intuitive drop-down menus—no additional software required. Try out one of our control page demos below and see how easy it is for yourself!
Peer-to-Peer Communication
Expand your I/O capability with the power of P2P communication, available on all ControlByWeb relays and PLCs. Control and monitor I/O on other 400 Series products and assign any device as master. It’s all the capability of a local installation with the flexibility of remote monitoring and control.
