HydroRanger 200 Communication Systems
The HydroRanger 200 is an integrated level controller capable of communicating process
information to a Supervisory Control and Data Acquisition (SCADA) system, via a serial
device such as a radio modem, leased line, or dial-up modem.
The HydroRanger 200 supports the following two communication protocols:
Modbus
Modbus is an industry standard protocol used by SCADA and HMI systems. The
HydroRanger 200 uses Modbus to communicate via the RS-485 port. For a description of
the Modbus protocol, contact your local Schneider representative.
Dolphin
Dolphin is a proprietary Siemens Milltronics protocol designed to be used with Dolphin
Plus.
