Intelligent sensor networks form the backbone of IIoT. Industrial Ethernet encoders can play here a particular key role, provided they are "equipped" accordingly. The sensors manufacturer Kübler equipped its Sendix F58 industrial Ethernet encoder family with the OPC-UA interface.
OPC-UA is establishing itself as an important interface within the framework of IIoT, in particular for cross-system communication (from machine to machine and from machine to the cloud). OPC-UA can forward machine data and has the distinctive feature of describing these machines semantically in a legible way. It therefore meets an important requirement for IIoT communication.
Kübler's Sendix Industrial Ethernet encoders can be upgraded additionally with this interface. These encoders therefore also offer the OPC-UA interface in addition to classical industrial Ethernet interfaces such as Profinet, EtherCAT or EtherNet/IP.
The encoder transmits both protocols simultaneously using the same connection, which allows, with a simple switch, sending data to the control as well as e. g. to a web server or to the cloud. This allows sending very easily condition monitoring data such as the temperature, error messages, operating times, voltage supply to the cloud. Intelligent "predictive maintenance" can therefore be implemented very easily in your SCADA concepts. Since every web-capable handheld device can be used to carry out important settings, configuring the encoder through OPC-UA becomes very simple. Service technicians can this way use their smartphone to set e.g. the preset value, the working range, the resolution of the encoder.
The optical absolute Singleturn and Multiturn Sendix F58 EtherNet/IP encoders with a diameter of 58 mm have been designed for time-critical applications. In addition to supporting plant performance and availability, their specific features also greatly contribute to save time and costs.
Equipped with their robust Safety-Lock™ bearing design, these encoders withstand installation errors, shocks and vibrations. Position value transmission is 5 times faster than common market encoders, therefore ensuring more performance. RPI time is only 1 ms. This feature allows operating this encoder in time-critical applications up to a 1,000 Hz update frequency. The fast start-up is another strong point of the encoder. It takes place immediately after applying the supply voltage. Therefore, nothing stands in the way of an increase of plant performance, of plant availability and of the reduction of costsensitive standstills. Cyclic services allow fast and easy commissioning and configuration, saving costs and time.
Thanks to the implementation of DLR (Device Level Ring) a single cable break does not lead to plant stoppage. Ring redundancy is ensured. These absolute Singleturn and Multiturn Sendix encoders are available in solid shaft or blind hollow shaft version. The blind hollow shaft has a diameter of 15 mm. Their IP65 protection level and their wide temperature range from -40°C…+80°C allow operating these encoders reliably also in harsh environmental conditions. Thanks to their optical sensors, these devices are 100% insensitive to magnetic fields. Total resolution is 32 bits. The devices are ODVA-certified.
