CHAPTER 7 Modbus/BSAP

Configuration

The Raven supports Modbus ASCII, Modbus RTU, BSAP, and can also emulate

other protocols like DF1 or others using its Modbus Variable feature.

Modbus Overview

The Modbus Protocol, developed by Modicon in 1979, provides for client-server

(also referred to as master-slave) communications between intelligent devices. As

a de facto standard, it is the most widely used network protocol in the industrial

manufacturing environment to transfer discrete/analog I/O and register data

between control devices.

Modbus, BSAP, and other Modbus variations are often used in conjunction with

telemetry devices.

This section is just a brief overview of Modbus. For more infor-

mation, refer to your Modbus equipment distributor or manufac-

turer or http://www.modbus.org.
