Vigilant IO-NET Programmable Control System (PA0498)

IO-NET is a low cost, distributed, field programmable control system that combines flexible control with networking communication facilities. It handles small or large numbers of inputs and/or outputs, whether concentrated at a single location or distributed over a wide area. All inputs are multilevel and can therefore provide the line supervision of input wiring often required for alarm applications. In addition, the IO-NET Controller can receive high level communications from a fire alarm system and use that information as additional input conditions for control logic. This combination of features makes IO-NET suitable for a wide range of control and telemetry applications: e.g. Alarm monitoring, AS 1668 Fire Fan Control, Mimic display of alarms, PLC with remote indication, Point-to-point telemetry, Remote annunciation, Stand-alone PLC. IO-NET uses a proprietary, token-passing bus communication protocol that ensures efficient network operation. Peer to peer communication is easily achieved as no “master” station is required to control network traffic. The network continues to function quickly even when the volume of information to be transmitted is high. A 2 wire (data only) or a 3 wire (data and power supply), multi-dropped connection is the standard IO-NET system communications medium without special cables. Data speeds are selectable from 1200 to 9600 baud. RS485, modem, radio, and fibre optic communications may also be used. An IO-NET System consists of at least one Controller. The Controller is connected to Termination Boards using flat ribbon cable looms. If connection to fire indicator panel communications is required then a RZDU to RS232 interface is also needed.
