Control Ready Performance For Wireless Networks
The future of wireless process control
The future is here. Plants are now controlling and evaluating critical processes over wireless networks; both need to be as reliable as wired networks for effective plant operation. With superior latency and reliability, Honeywell's OneWireless™ solution was built from the ground up for control-ready performance.
FACT
Honeywell customers are already running open-loop control and critical monitoring applications with transmitters operating at a 1 second or 5 second update rate.
Robust control-ready performance with OneWireless
Globally, Honeywell OneWireless has given end users like you the confidence to implement wireless across the enterprise. Just as the change from pneumatic and analog to digital architectures enabled operational improvements, the dramatic benefits of wireless will take performance to the next level, with Honeywell in the vanguard of that movement.
Manufacturers seeking the best wireless network and device performance, as well as future scalability and protection of their technology investments, will opt for Honeywell’s OneWireless solution. With superior latency and reliability, it leads the way in controlling production processes over wireless networks.

Network latency
A major roadblock to the implementation of wireless control in industrial plant applications is the issue of network latency. During a tank overflow situation, for example, a 30-second delay in data updating is clearly unacceptable. In fact, any wireless mesh network that suffers from latency issues is unacceptable for use in a control situation.
A multi-hop wireless mesh network, such as that employed by others, has increased potential for latency in communication since data may have to jump from device to device before reaching a gateway. This situation can also increase transit time in data reporting. By contrast, Honeywell’s OneWirelessTM solution provides high reliability and throughput, as well as superior determinism and latency control, in order to support multiple-use applications.
FACT
The competition’s data update rates range from 8 to 12 seconds; Honeywell OneWireless supports 1-second reporting with latency control and the ability to configure sensors on the same network at different rates.
Industrial Wireless Standards - ISA100.11a & WirelessHART Protocols
When considering a wireless solution for industrial process control, flexibility, scalability and investment protection are extremely important. Today, two major wireless protocols exist: International Society of Automation's ISA100.11a standard and IEC 62591 WirelessHART specification.
FACT
The user-driven ISA100.11a standard handles a much higher volume of process data, and ensures interoperability between wireless field instruments from different vendors.
ISA100.11a protocol represents a comprehensive industrial wireless approach that serves a broad, facility-wide wireless network for both process and discrete manufacturing. The technology is designed to meld various specifications such as FOUNDATION Fieldbus, Modbus, Profibus, HART and Common Industrial Protocol (CIP). It supports a wireless platform for diverse operations on the plant or factory floor and enables an open and interoperable application environment, while at the same time providing a robust backhaul to the Process Control Network (PCN). It can emulate legacy application layers for any wired fieldbus, and integrate with existing control systems. You can reuse proven tools and interfaces to reduce development and testing time—resulting in faster and less expensive implementations.
WirelessHART, part of the HART 7 specification, is an open communication standard for transmission of HART messages over wireless instead of a 4-20 mA or RS484 medium, and uses the same command structure found in 4-20 mA-based HART devices.
The user-driven ISA100.11a standard handles a much higher volume of process data, and ensures interoperability between wireless field instruments from different vendors. Honeywell's OneWireless was built from the ground up to support the ISA wireless protocol to safeguard your wireless investment.
