Redundant wireless system

Honeywell's OneWireless R120 features a redundant wireless system gateway (WSG), a critical prerequisite for wireless process control.

The WSG manages data between wireless field instrumentation and the plant's process control network (PCN). It serves as a backup gateway to ensure that data is always delivered even if the main gateway malfunctions or fails. Paired with existing OneWireless redundancy features, this approach creates an industrial wireless system with hardware and radio-frequency redundancy from the field instrument to the PCN connection. Additionally, failure recovery features help prevent data loss and the network can recover in less than two seconds from any field hardware failure.

The system can accommodate multiple communication protocols and field devices on a single network to help improve overall plant safety, reliability and efficiency. Each gateway can support up to 100 transmitters, and a single OneWireless server can support up to 40 gateways.

The system includes several other enhancements that improve the network scalability and reliability such as adaptive transmit power control for XYR 6000 field instruments. This feature saves battery power and minimises radio interference by enabling field devices to use the least amount of power possible to transmit signals to OneWireless multinodes, or access points.

OneWireless products now ship with OneWireless R120 software or firmware. Any existing OneWireless devices installed at user sites can be easily upgraded by an over-the-air software update to support the new functionality while supporting current investments.
