Description

Designed specifically for SCADA and process control applications with a Star topology, the TC8916 Broadcast & Receive Device broadcasts & receives information from remote devices. Transparent to all data sent in either direction, it is typically used to link SCADA Hosts to remote terminal units (RTUs) or programmable logic devices (PLCs) via fiber optic or metallic cable.

The host port on the TC8916 receives a broadcast message from the host controller and broadcasts the message out through up to 23 ports at the same time. The broadcast message (sent by SCADA HOST) has embedded Identification (ID) numbers for each RTU. Only the RTU that matches this ID number will respond.

The TC8916 supports data rates up to 120 Kbps and is compatible with both RS-232 and RS-422 interfaces. Interfaces can be mixed or matched in increments of four.

Typical Application (Application Questions)

The TC8916 is often used in SCADA applications with a Star topology to link a SCADA Host to RTUs. The TC8916ís RS-232/RS- 422 user ports can be extended with the use of a fiber modem or multiplexer. When the Host Polling Device sends information to the TC8916 via the RS-232/RS-422 Host Port, it will broadcast to each of the RS-232/RS-422 user ports. The addressed remote device(s) will then respond back to the Host Device.
