About This Manual This manual describes how to program the Technosoft intelligent drives equipped with EtherCAT® communication interface. These drives support CAN application protocol over EtherCAT® (CoE) in conformance with CiA 402 device profile. The manual presents the object dictionary associated with this profile. The manual also explains how to combine the Technosoft Motion Language and the CoE commands in order to distribute the application between the EtherCAT® master and the Technosoft drives. In order to operate the Technosoft drives with EtherCAT® communication, you need to pass through 3 steps: Step 1 Hardware installation Step 2 Drive commissioning using initially the Technosoft EasySetUp or EasyMotion Studio software platforms and later via an EtherCAT® master Step 3 Motion programming using one of the options: A. An EtherCAT® master B. The drive built-in motion controller executing a Technosoft Motion Language (TML) program developed using Technosoft EasyMotion Studio software C. A distributed control approach which combines the above options, like for example a master calling motion functions programmed on the drives in TML This manual covers steps 2 and 3. For step 1, refer to the Technical Reference manual specific for each drive. Scope of This Manual This manual applies to all Technosoft intelligent drives having an EtherCAT® communication interface. © Technosoft 2014 III CoE programming Notational Conventions This document uses the following conventions: AL – Application Layer CoE - CAN application protocol over EtherCAT® ControlWord.5 – bit 5 of ControlWord data ESM – EtherCAT® State Machine IP - interpolated IU – drive/motor internal units TML – Technosoft Motion Language CSP – Cyclic Synchronous Position CSV – Cyclic Synchronous Velocity CST – Cyclic Synchronous Torque X1 – Subindex 1 of object 60C1h - Interpolation data record X2 – Subindex 2 of object 60C1h - Interpolation data record Trademarks EtherCAT® is registered trademark and patented technology, licensed by Beckhoff Automation GmbH, Germany Related Documentation Technical Reference Manual of each intelligent drive with EtherCAT® interface – provides information needed for hardware installation: technical data, connectors pin assignment, wiring diagrams plus a detailed presentation of drive setup procedure. Help of the EasySetUp software – describes how to use EasySetUp to quickly setup any Technosoft drive for your application using only 2 dialogues. The output of EasySetUp is a set of setup data that can be downloaded into the drive EEPROM or saved on a PC file. At power-on, the drive is initialized with the setup data read from its EEPROM. With EasySetUp it is also possible to retrieve the complete setup information from a previously programmed drive. EasySetUp can be downloaded free of charge from Technosoft web page Motion Programming using EasyMotion Studio (part no. P091.034.ESM.UM.xxxx) – describes how to use the EasyMotion Studio to create motion programs using the Technosoft Motion Language (TML). EasyMotion Studio platform includes EasySetUp for the drive/motor setup, and a Motion Wizard for the motion programming. The Motion Wizard provides a simple, graphical way of creating motion programs and automatically generates all the TML instructions. With EasyMotion Studio you can fully benefit from a key advantage of Technosoft drives – © Technosoft 2014 IV CoE programming their capability to execute complex motions without requiring an external motion controller, thanks to their built-in motion controller. A demo version of EasyMotion Studio (with the corresponding EasySetUp part fully functional) can be downloaded free of charge from Technosoft web page.

Note: Most of the documentation here is directly stolen from the CANopen Wikipedia page. This documentation is a work in progress. Feedback and revisions are most welcome! CANopen is a communication protocol and device profile specification for embedded systems used in automation. In terms of the OSI model, CANopen implements the layers above and including the network layer. The CANopen standard consists of an addressing scheme, several small communication protocols and an application layer defined by a device profile. The communication protocols have support for network management, device monitoring and communication between nodes, including a simple transport layer for message segmentation/desegmentation.

  • Ethercat the New Standard for Measurement Applications Central Backbone for Distributed Systems
    C5.2 EtherCAT The new standard for measurement applications Central backbone for distributed systems Dr. Kessel, Jens-Achim ADDITIVE Soft- und Hardware für Technik und Wissenschaft GmbH Max-Planck-Str. 22b, 61381 Friedrichsdorf Abstract In the past years EtherCAT has become a world wide accepted new standard in automation and control. In November 2003 the EtherCAT Technology Group (ETG) was founded and it has grown up to about 900 members from 45 countries in January, 2009. EtherCAT was designed and developed as an open high performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet technology to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. Once the new standard was introduced for automation and control, it became interesting, too, to use Eth- erCAT also for distributed systems in measurement applications. This paper takes a focus on the special properties of EtherCAT with respect to the usability in measure- ment applications. It shows the capabilities of EtherCAT as a powerful backbone, replacing classical net- works based on CAN or ProfiBUS. In particular aspects of synchronisation and real-time-processing in combination with the compact data packaging are interesting for measurement applications with a big number of distributed analog channels. E.g. in applications where torque and speed of rotating parts are picked up just to measure, to detect or even to prevent oscillations, it is very important to synchronize the sampling of data at the distributed converter modules. Only this allows then to calculate exact phase in- formation from the measured signals and evaluate and prepare the data according to the requirements of an application on top.
