Device communication systems
The device 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 device supports the Modbus protocol, an industry standard used by SCADA and HMI
systems. The device uses Modbus to communicate via the RS-485 port.
The standard unit may also be enhanced with Siemens SmartLinx communication modules
that provide an interface to popular industrial communication systems.
This manual only describes the built-in communications. Please consult the appropriate
SmartLinx manual for other information.
