WirelessHART networks for process automation
Wireless communication quickly gains relevance in automation applications. For process automation, it is not the amount of data that poses challenges, but the distances to be bridged. Whenever the plant architecture does not allow conventional wiring, values are only accessible through frequent visits to the field.
WirelessHART offers a cost efficient solution. Measured values become available on a regular basis, which leads to increased quality and more economical operation of process plants.
In a WirelessHART based network, every participating device simultaneously works as a signal source and a repeater. Through the routing of the individual signals across the entire network, a wide network structure becomes possible.
WirelessHART products from Pepperl+Fuchs
Pepperl+Fuchs offers several modules to connect sensors to a control system or asset management system with a wireless network. These WirelessHART products support the installation of field devices from different manufacturers without the need for additional wiring effort and costs. A reliable, interference-free communication is established with the following components.
Gateways
The core element and most advanced device within a WirelessHART network is our WirelessHART gateway, which establishes the wireless connection to the network. It offers one or more interfaces for host systems (RS 485, Ethernet, PROFIBUS) and is equipped with “Network Manager” and "Security Manager".
Adapters
WirelessHART adapters can be connected to every conventional HART or 4 mA … 20 mA field device directly or with a short cable. They read the data of the field device via HART or translate the 4 mA … 20 mA signal to a digital value and transmit the data to the WirelessHART network. These highly flexible solutions turn every field device into a WirelessHART field device.
Temperature Converter
The WirelessHART temperature converter is a field device that is already equipped with a WirelessHART interface. In this case, the 4 mA…20 mA interface is replaced by an antenna.
3-D Simulation
Wireless Network Checker (WiNC) from Pepperl+Fuchs consists of two software programs. With these programs, you can create a virtual model of your plant and quickly generate a three-dimensional simulation of your WirelessHART network. This enables you to simulate and verify the radio wave propagation of individual devices and their interoperation inside a network.
Accessories
Pepperl+Fuchs offers a variety of accessories for WirelessHART installations. The portfolio consists of antennas, adapters, coaxial cables, and surge protectors.
