System Overview 2-21
Modbus
Modbus is a protocol that allows for communication between
multiple devices connected to the same network, and is often used
to connect a supervisory computer with a remote terminal unit
(RTU) in supervisory control and data acquisition (SCADA)
systems. ADS uses Modbus to make information available to RTUs
or SCADA systems directly.
FlowShark models AG-M, CG, CG-1, CL, CS, BG, and BL support
Modbus ASCII communication. Refer to Chapter 9, Modbus, for
more information on the installation and configuration of a
FlowShark monitor supporting Modbus communications.
Note: FlowShark models AG, AL, and AS can support
Modbus with the installation of a retrofit kit to add external
power and provide external cabling.
