10/12/2004 - For the first time during the electronica 2004 in hall A6.420, Unitronic presents an certified Ethernet-Powerlink-complete solution applicable for any kind of control system or field device ready for SOP: the Ethernet-power link interface module Micro WebTarget MWT3/RTE and a high-precision protocol-stack, both by Smart Network Devices. These hard- and software components introduced do not only allow a rapid and safe access to the world of real-time-Ethernet – the certification, moreover, ensures that the Ethernet-Powerlink-specification in the actual version 2.0 is completely and provably adhered to.
Based on the 32-bit-RISC/DSP-communication processor hyNet32XS by Hyperstone and the Embedded Operating System HyNetOS by Smart Network, the MWT3/RTE-board impresses with small dimensions of only 3x4 cm2 as well as with outstanding performance data. Working in master mode (EPL managing node) the CPU is able to serve a fast number of knots with cyclic time of 200µs and less, in slave mode (EPL controlled node) response times of min. 2µs are guaranteed. A hub integrated in the Micro WebTarget takes over the lines wiring significant in automation. The hub’s cycle time is less than 400µs. As a result, 10 times higher cycle times are possible than with any Ethernet-switch.
Further external components – like e.g. normal pc – can be coupled via a third Ethernet-interface so that the MWT3/RTE-board can also be used as a gateway or router. Thereby, a transparent access via TCP/IP from the PC to any network node is also possible in the real-time range.
Due to an internal 128KB memory and the modular structure of the HyNetOS, an external DRAM for slave-knots becomes redundant. The flash-memory can even be resigned, if the knot is booted via network instead of the local flash-memory.
Also with their certified Ethernet-power link-stack Smart Network Devices sets standards. Response times of 2µs and a synchronisation-jitter of <500ns require a high-precision coordination of protocol-software and hardware. During the Ethernet-power link-certification these system parameters are recorded by a high-precision timing-analyser with an accuracy of 20ns and they are logged for every device on a data sheet notarised by a neutral part. Smart Network Devices’ module solution guarantees that these high capacity standards are being observed in practice, too.
For device manufacturers, who build up their products on Smart Network Devices’ technology an Ethernet-Powerlink-certification will be possible from beginning of November 2004 on.
Rolf Breiden has founded Unitronic AG, since 2002 member of the Swedish Holding Lagercrantz Group AB, in 1970. The company’s target is to back-up customers energetic and maker-spanned in German-speaking areas by competent Design-In- and After Sales-Support with the choice and implementation of newest technologies.
Franchise contracts with over 40 leading manufacturers of semiconductors, sensors, displays and modules for telematics, telemetry, navigation and connectivity guarantee an utmost flexibility regarding the choice of products that are best eligible for the customers’ application.
In Germany, 32 employees in six sales offices provide proximity to customers. Since two years Unitronic are also present in Switzerland und Austria with their affiliated companies SECOS GmbH and Novatronic GmbH
Smart Network Devices GmbH
Smart Network Devices GmbH (SND), established in 1999 in Neuss and now situated in Jülich, have developed an innovative technique of their own, that makes it possible to handle complex communication requirements in wired and wireless nets of the future on one single chip (System on Single Chip).
Within shortest, SND advanced to one of the global leading business companies in this scope with cutting edge products like the Embedded-Network-Operating-System HyNetOSTM, the Micro WebTargetTM-Board, the Bluetooth-Board Micro BlueTargetTM as well as divers software-protocol-extensions (e.g. TCP/IP, HTTP, FTP, SSL, SNMP, Bluetooth-protocol-stack) for HyNetOSTM. Today, SND’s solutions allow an effective and platform-independent “Embedded Networking” in fields like Industrial Automations, Facility Management, wireless Infrastructure etc.
