The webletter for Real-Time-Ethernet-Communication with sercos III
Hannover Fair 2009
Numerous members of sercos International are participating in a joint booth at the Hannover Messe (April 20 – 24, 2009), presenting their sercos products and components in an 80 square meter booth, D23 in Hall 9.
On April 21, a press conference and the annual members meeting including the elections of the board will take place.
sercos News 01/2009 available!
Issue 01-2009 of the sercos News is now available. The latest issue of the sercos News contains details about the latest developments of the Real-Time Ethernet System sercos III, plus more.
Axis control module for sercos III
In addition to the three sercos III modules from the Inline I/O product line from Phoenix Contact, the new sercos III module from the Inline Block product line for controlling axes allows two motion axes with different drive technology to be even more flexibly and cost effectively controlled. The axis control module, which also includes an I/O for autonomously controlling the motion axes, can be connected to two drive amplifiers and two incremental encoders for position sensing together with digital I/Os for end position and reference switches.
This makes the module especially suitable for controlling motion where there are no control electronics available with an integrated sercos III interface. In practice these include, in addition to servo valves for pneumatic or hydraulic cylinders, drive amplifiers for electric motors with low power ratings or simple frequency inverter-controlled axes. This means that motion functions without a direct sercos III interface can be coupled in real time to your PLC or motion control system. For the axis control module, the device description files (SDDML), which are requi red for user-friendly parameterization, can be downloaded.
Schleicher Electronic banks on sercos III
Schleicher’s XCx 1100 is a high-speed control system that can be used for a wide range of very demanding applications. The controller runs two operating systems in parallel: the high-precision real-time operating system VxWorks executes the control tasks while Windows XP Embedded is available for applications with an integrated user interface.
The basic XCx 1100 model is equipped with a Celeron M 1.5 GHz, but the controller can be upgraded up to an Intel 2 Core Duo. Featuring a solid state disc with 4 GB memory or more, the XCx 1100 does not require mass storage with rotating mechanical parts and operates without ventilation.Thus, safe and reliable operation is ensured even in rugged environments. The system combines motion control, CNC, and PLC functions according to IEC 61131.
sercos III for IOs, valve terminals and welding tongs
The netIC of the company Hilscher, offered for integration within a device, comes as a plug-in module in the form of a DIL32-IC with dimensions of 21 x 42 mm. For connection to the sercos network only the RJ45 double socket with integrated transformer and LEDs is additionally provided. The module is based on the netX 50 with a sercos III slave stack in Version 1.1. An UART with MODBUS RTU protocol, SPI or I2C is available as serial host interfaces. Other protocols can be implemented on customer request. As an alternative, direct digital I/Os can be actuated via serial shift registers. There is an easy to use tool available for configuration.
Cabling System and Components
HARTING offers the complete range of cabling components for the installation of passive infrastructure according sercos III in industrial and automation environments. The wiring solution is continuous 4- or 8-wired, screened cabling for the connection of automation solutions and controllers suitable in switch cabinets (IP20) as well as in harsh IP 65/IP 67 environments. Basically RJ45 connectors and M12 connectors in D-coding are used. The product range consists of outlets and distribution modules, panel feed-throughs, madeup system cords, connector sets to make-up cables on site, as well as cables for fixed and flexible installation. All components are designed to be modular and can therefore be combined as required by the special installation requirements. System cords and connecting cables can be purchased either as ready made-up and tested or as on-site self assembly sets.
sercos III PCI board with DMA capability
Automata has expanded its product range of sercos III PCI boards by a version with DMA capability. Thanks to this feature the fast data exchange between application and communication board required by real-time Ethernet protocols can be guaranteed.
The board is available with one or two real-time Ethernet interfaces. Both interfaces are compliant to the sercos III, EtherCAT and Powerlink standards. Beside the DMA capability 8 MB FLASH, 4 MB SDRAM and 512 kB NVRAM are present onboard.
