Link Selector X20HB8884

Systems with redundant cabling can be implemented easily using POWERLINK. Unlike ring redundancy, cable redundancy does not require cable looping, which can sometimes be problematic. This allows the creation of all types of tree structures. When using a device with the link selector function, data is always transferred via the highest quality network lines. The link selector function is integrated in the X20HB8884 compact link selector. This makes it easy to connect any POWERLINK device to a redundant POWERLINK network.

netTAP 100 – IP20 POWERLINK Gateway

Whether a Master or Slave conversion to PROFIBUS, CANopen, DeviceNet, Modbus RTU, ASCII, 3964R or netSCRIPT is needed in your POWERLINK application the industrial gateway series netTAP 100 will provide you a suitable conversion solution for your needs. It features transparent data transfer between the two protocols, is compatible with all major PLCs and is easy to commission with a common configuration tool. netTAP 100 is the protocol converter for sophisticated conversions and supports 2-port Real-Time Ethernet to serial, Fieldbus to Fieldbus, Real-Time Ethernet to Fieldbus and Real-Time Ethernet to Ethernet conversions. It supports slave and master functionality in any combination. Master functionality is unrestricted when licensed. A memory card slot allows the user to save firmware and configuration data on a removable card. In case of failure all that is necessary to bring the plant back on line within seconds is to move the memory card from the old netTAP 100 onto a spare unit. Apart from standard protocols, netTAP 100 supports the creation of serial protocols with the Lua-based scripting language netSCRIPT. A full featured development environment is included within the delivery. It allows the comfortable and rapid programming of any proprietary serial protocol as well as the I/O data pre-processing during the conversion into the other field protocol.

Communication Module (MXI) POWERLINK

The POWERLINK communication module (MXI) allows you to expand your 9400 Servo Drive into an ETHERNET POWERLINK node. The drive can be used as a Controlled Node (CN) or a Managing Node (MN), meaning it can perform motion control tasks without the need for an external control. The integrated 2-way hub enables linear wiring to be implemented without external components. Five LEDs make it easy to diagnose the device and bus states. You set the device address via a DIP switch.

Lenze SE


Lenze offers an external 8-way hub to complement the 2-way hub integrated in the ETHERNET POWERLINK interface modules. This infrastructure component corresponds to a class II repeater in accordance with IEEE802.3/u. It automatically detects whether it is being operated in a 10 Mbps or a 100 Mbps network. Hubs can be cascaded via a special uplink port.

The openHUB is an open-source implementation of an Ethernet Hub that can be used universally in standard Ethernet networks or POWERLINK networks. It is suitable for 100 Mbit/s (Fast Ethernet) networks. VHDL source code of openHUB is available on sourceforge at


In addition to wired communications interfaces such as a digital input and a digital output, 2 x CAN, Ethernet und RS232, the ESX-TC3G also provides a USB interface for service purposes.

For data exchange via radio, an optional 2G/3G mobile radio connection, WLAN and Bluetooth are available. The ESX-TC3G is equipped with a GPS/GLONASS receiver for position determination. The ESX-TC3G is available in two different antenna versions, with integrated antennae or connections for external antennae.

Contactless POWERLINK Data and Power Transmission for Rotating Systems

The contactless data transmission modules for rotating systems are used, among other things, wherever safe data transmission by means of slip rings is no longer ensured, due to large outer diameters of the system and higher data rates.
Key features of the BN 636699:

  • Automatic recognition of the bus speed for Ethernet-based protocols up to a net data rate of 1 Gbit/s, BER lower than 1 x 10 -12
  • Multi-channel design available, also simultaneous transmission of other bus protocols possible in parallel to Powerlink
  • Maximum immunity to interference thanks to the enclosed design, no WiFi
  • Operation independent of the rotational speed and direction of rotation from 0 to 3,000 r/min with constant transmission quality; ready for use directly after the system has been switched on
  • Maximum reliability and service life through maintenance-free operation without abrasion
  • Modules with free inner diameters of up to 300 mm available
  • Combinations with contactless power transmission of up to 300 W at 24VDC available
