SCADA Applications Over MOTOTRBO


The Tallysman TW200 SCADA Device provides secure and reliable end-to end SCADA and Telemetry communication over Motorola MOTOTRBO™ radio systems. The TW200 provides serial port (RS232) pass-thru connectivity for Remote Terminal Equipment (RTU) and Supervisory Control and Supervision systems (SCS).

The TW200 support 300 byte data payloads. Transmissions are triggered in response to a SCS poll or an autonomous alarm event triggered by an RTU. The time to complete a typical system poll and receive a RTU response is less than 3 seconds.

The SCS Control Station radio is configured to “broadcast” messages in a point to multi-point configuration. RTUs receive all messages and respond only if the data payload addressing matches their own.
