The ideal wireless technology for your application

In practice, various wireless technologies have proved suitable for a range of applications. Phoenix Contact provides industrial-grade wireless solutions suitable for your applications.

  • WLAN IEEE 802.11: Wireless Ethernet – for high-performance industrial-grade Ethernet networks
  • Bluetooth:: Wireless Ethernet and Wireless I/O – for transmitting control data in factory automation
  • Trusted Wireless: Wireless I/O and Wireless Serial – for signal and data transmission in large-scale systems
  • WirelessHART: Wireless Serial – for signal transmission in the process industry with proven HART communication

IWLAN – Industrial Wireless LAN

Industrial Wireless LAN, or Industrial WLAN or IWLAN for short, allows easy wireless connection in PROFINET, EtherNet/IP™, or Modbus/TCP networks, and is often also called Wireless Ethernet. IWLAN is characterized by the fact that geographically large networks can be constructed with several devices. One particular asset they have is roaming, thanks to which freely mobile devices in a large WLAN network can make their wireless connection automatically to the access point with the best wireless signal.
This makes IWLAN perfect for applications such as driverless transport systems and warehouse shuttles, electric monorail systems, and operating machinery and systems via tablet and smartphone. With PROFIsafe, even safety-related applications can be controlled via wireless. Phoenix Contact provides a variety of different IWLAN products for different applications.

Industrial Bluetooth

Bluetooth is known primarily from the fields of mobile communication and computer accessories, but has also become established as a communication option in the field of machine building and systems manufacturing. Bluetooth is extremely robust against disruptions in the frequency band and enables reliable operation in parallel with other Bluetooth or WLAN applications. This means that Bluetooth can be used to establish very reliable wireless connections, which are essential for safety communication (PROFIsafe, SafetyBridge, etc.), among others. Bluetooth is particularly suitable for small, static wireless network applications with a small number of devices (point-to-point application and small networks with up to seven devices). Overall, Bluetooth is exceptionally well suited for transferring Ethernet and PROFINET data and I/O signals to mobile or rotating machine parts.

WirelessHART is a subset of the HART 7 standard and is an energy-efficient wireless technology designed for wireless process measurement applications, eliminating traditional 4...20 mA signal wires. The main feature of WirelessHART is its ability to set up and configure meshed networks autonomously. This enables every end device in the network to communicate redundantly via several different paths. Fully meshed networks are also self-healing, which guarantees long-term reliability and predictability, even under changing environmental conditions. Moreover, the WirelessHART standard allows reliable parallel operation, chronologically synchronized communication for fault-free wireless channel management, and secure transmission of information.

WirelessHART adapter

Easy integration of field devices – thanks to WirelessHART adapter

WirelessHART adapter – Connect remote field devices to the network

The WirelessHART adapter is the clever alternative to cable-based HART programming. Simply connect the WirelessHART adapter directly to the field device or to any accessible point in the analog loop, and just like that, it’s part of your network. The power supply of the WirelessHART adapter is flexible and can be adapted to your requirements.

  • Reduce installation costs by using a 4…20 mA loop-powered power supply, or use a separate DC power supply as an alternative
  • Connect up to four HART devices per adapter without a 4…20 mA signal with multidrop mode: The adapter is supplied via a separate DC voltage, and the connected devices are then supplied by the adapter
  • Integrate 4…20 mA devices that are not HART-compatible into a WirelessHART network: The connected devices are supplied via the power loop of the adapter, after which the power loop is measured and transmitted as a process value
  • Programming with a HART programming tool: Connected HART devices can be programmed directly without having to reconnect the programming tool

WirelessHART gateway – integrate difficult-to-access sensors into your network

The WirelessHART gateway allows you to integrate hard-to-reach sensors into your network with very little effort. In accordance with the HART standard, the system consists of an access point, a network manager, and a gateway. The access point establishes the connection to the various devices wirelessly. The network manager is the software that controls the meshed network, optimizes data traffic, and ensures security and authentication for field devices. The gateway is the portal between the system network or host system and the WirelessHART network. It includes the physical Ethernet interface as well as the Modbus/TCP protocol.

  • Easily connect up to 250 WirelessHART field devices via the Ethernet port or the integrated WLAN client transceiver
  • Integrate devices into all common asset management systems using Modbus/TCP
