WirelessHART is the first open and interoperable wireless communication standard designed to address the critical needs of process industry users—reliable, robust and secure wireless communication in real world industrial plant applications.

The combination of HART plus wireless is a major step for the industry. WirelessHART provides new capabilities for users to get information on process parameters and to monitor the performance of plant assets in areas that have previously been technically or cost-effectively difficult to achieve. It extends the Power of HART into areas that were difficult to reach with conventional wired systems and provides low cost digital access to installed HART devices.

A backward compatible extension to the HART Protocol, WirelessHART provides the same user experience, ease-of-use, flexibility and friendliness that users expect from HART-enabled products.

WirelessHART

• provides an alternate method for Users to access measurement and monitoring information for existing HART-enabled devices
• enables a cost-effective alternative to adding new or additional measurements to a control, asset management, safety or other system
• delivers new device power options for additional devices
• includes new low risk and low investment options for non-wireless devices
• has no impact on current HART-enabled devices or existing 4-20mA measurement and control loops

WirelessHART Features

Process Monitoring
WirelessHART dramatically reduces the cost and complexity of installing and commissioning HART-enabled devices. This enables a new range of monitoring control applications that were impractical or impossible with wired technology.

New Measurement or Monitoring Points
Add measurements that were too costly to implement with wires.

Access to multivariable information
Retrofit existing HART devices with WirelessHART adapters to digitally access all variables – without touching the existing 4-20mA connection.

Eliminate error-prone and expensive manual processes
Automate the collection of non-critical measurements and integrate with data historians or device maintenance applications.

Device Status and Diagnostics

WirelessHART is a simple and cost-effective way to gain full digital access to valuable HART information.

Status and Diagnostic Alerts
Combining WirelessHART with newly added publishing features in HART provides a very effective alerting solution. WirelessHART devices can publish on a schedule or on exception. Published information may include device malfunction, Primary Variable (PV) analog output saturated, fixed or out of limits, configuration change, cold start and more.

Field Device Diagnostics and Troubleshooting
These commands include: perform loop test, initiate self test, get more status available information, set primary variable units, set damping value, loop current alarm action and more.

Commissioning
Device setup and commissioning is faster when similar configuration parameters are the same for multiple devices. Configuration tools allow fast and easy configuration duplication that greatly minimizes device setup errors and facilitates fast device commissioning. Device configuration can be done with a handheld configurator, a PC running configuration software or a device management application.
