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 information,
refer to your Modbus equipment distributor or manufacturer or http://
