Integration Ready
We support HTTP GET, XML, JSON, SNMP, Modbus TCP/IP, and our Cloud API with more on the way.
No-Code Programmable Logic
Our intuitive Task Builder empowers you to build custom logic using drop-down menus in an if-this-then-that flow.
P2P Networking & Remote I/O
Devices can communicate through Peer-to-Peer (P2P) networking to share I/O among other ControlByWeb controllers, assign any device as master, set up multiple masters, and link remote inputs and relay control.
Email Notifications
Stay in control of operations with real-time monitoring. Add intelligence to your emails through programmable logic to instantly send notifications to the right people and eliminate false alarms.
Easy-to-Use Embedded UI
Our devices come with a simple embedded user interface that will enable you to easily monitor, manage, and control ControlByWeb PLCs from any standard web browser.
Data Logging
Enjoy scheduled and conditional logging with email and FTP log exports. Add the optional ControlByWeb Cloud for remote access and downloadable logs.
Cloud Compatible
Enhance your capabilities with the ControlByWeb Cloud. Gain enhanced features such as simplified remote device access, data logging, and advanced analytics.
Trusted Device Security
Our controllers have no built-in OS or file system, making them less prone to vulnerabilities. Third-party consultants and government agencies test the cybersecurity of our controllers.
IIoT Monitoring & Control
Access the device directly through an assigned IP address. Set up your network settings the way you want, to limit or allow remote access through the cloud.
