Fast Communication between Automation and Field Devices: MODBUS

The MODBUS protocol is a communication protocol based on master/slave or client/server architecture. The primary purpose of the protocol is facilitating reliable, fast communication between automation and field devices.

Advantages with MODBUS:

  • Uniform data exchange compliant with standards
  • Very fast data transmission
  • Independent of technology and manufacturer

MODBUS Explained Simply

The well-established MODBUS protocol has become the de facto standard. It extends the MODBUS protocol familiar since 1979 for programmable logic controllers. The advantage: MODBUS is a streamlined protocol that ensures ultra-fast ETHERNET data transmission. A manufacturer-independent data structure also permits communication between devices from different manufacturers.
