Communication Protocol for Flexible Integration of Flow Meters & Controllers
Modbus RTU
- Flexible systems integration and automation
- Establish master-slave/client-server comms
- Most widely used protocol in manufacturing
- Transfer discrete/analog I/O
- Register data between devices
Overview
Sierra supports Modbus RTU digital communication protocol for flexible integration of our flow meters and controllers into any automation or control system. In the industrial manufacturing environment, Modbus is:
- A de facto standard
- Truly open
- The most widely used network protocol
Modbus is a true lingua franca or common denominator between different measurement and control device manufacturers. For more information on the Modbus digital communication protocol, visit the Modbus organization website.
