TBox combines alarm notification, data logging, integral web server, IP telemetry, and programmable automation in a single, rugged package. TBox uniquely supports a broad range of core functionality.

The benefits of TBox:

Using push messaging via e-mail, FTP, and SMS text, TBox will immediately notify users of alarms and live conditions in a reliable manner that minimizes communications networking costs.

For compatibility with existing systems, TBox also supports “pull” messaging using SCADA protocols such as Modbus.

An integral web server allows TBox to manage Internet and intranet communications without a front end device and provides a very inexpensive HMI for operations and maintenance.

Programmable Automation using IEC 61131-3 Ladder Diagram, Basic, and Microsoft Windows Automation environments expedite configuration of automation tasks and custom calculations for virtually any remote asset or process.

Alarm management and data logging provide live information and historical data to multiple recipients.

Multi-communications via a choice of integral, communication options provide broad compatibility and mean that all remote sites are accessible. TBox communications capabilities allow use in IP forwarding and intelligent sensor gateway applications.

TBox MS combines the power of the Internet with modular-based architecture to create a class-leading remote control and automation solution.


The TBox LT2's all-in-one architecture provides up to 50% cost savings over other solutions that combine PLC, communications, & SCADA.
