OneWireless R120 process control system

Honeywell has introduced the latest version of its OneWireless industrial mesh network system for manufacturing facilities. OneWireless R120 is claimed to feature the process industry's first redundant wireless system gateway, a prerequisite for wireless process control.

The gateway manages data between wireless field instrumentation and the plant's process control network. 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 creates what is claimed to be the first industrial wireless system with complete hardware and radio-frequency redundancy from the field instrument to the PCN connection. 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 thousands of 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 server can support up to 40 gateways. It includes several other enhancements that improve the network scalability and reliability such as adaptive transmit power control for XYR 6000 field instruments. This saves battery power and minimises radio interference by enabling field devices to use the least power possible to transmit signals to multinodes or access points.
