Windows Embedded CE 6.0 Professional operation system (MICROSOFT)

Windows Embedded CE 6.0 R3 is a real-time operating system for a wide range of small-footprint consumer and enterprise devices. Development tools like Platform Builder, a Visual Studio 2005 plug in, provide an integrated development environment (IDE) that enables you to build applications and Windows Embedded CE operating system software in a familiar environment.o.

EtherCAT communication channel between CNC and its peripheries (BECKHOFF)

EtherCAT is the open real-time Ethernet network originally developed by Beckhoff. EtherCAT sets new standards for real-time performance and topology flexibility.

The EtherCAT technology overcomes the system limitations of other Ethernet solutions. The Ethernet packet is no longer received, then interpreted and copied as process data at every connection. Instead, the Ethernet frame is processed on the fly, the newly developed FMMU (fieldbus memory management unit) in each slave node reads the data addressed to it, while the telegram is forwarded to the next device. Similarly, input data is inserted while the telegram passes through. The telegrams are only delayed by a few nanoseconds.

EtherCAT reaches new dimensions in network performance. Thanks to FMMU in the slave nodes and DMA access to the network card in the master, the complete protocol processing takes place within hardware and is thus independent of the run-time of protocol stacks, CPU performance or software implementation. The update time for 1000 distributed I/Os is only 30 µs. Up to 1486 bytes of process data can be exchanged with a single Ethernet frame – this is equivalent to almost 12000 digital inputs and outputs. The transfer of this data quantity only takes 300 µs.

EnDat22 (physical) absolute measurement system (HEIDENHAIN)

The EnDat interface from HEIDENHAIN is a digital, bidirectional interface for encoders. It is capable both of transmitting position values from incremental and absolute encoders as well as transmitting or updating information stored in the encoder, or saving new information. Thanks to the serial transmission method only four signal lines are required. The data are transmitted in synchronism with the clock signal from the subsequent electronics. The type of transmission (position values, parameters, diagnostics, etc.) is selected by mode commands that the subsequent electronics send to the encoder.

This bidirectional EnDat 2.2 interface is now available with a clock frequency of 16 MHz for high-response applications with direct drives, especially those found in the electronics industry. The increase from 8 MHz to 16 MHz significantly reduces the access time to the position value, and makes shorter cycle times possible. This means that EnDat 2.2 is now the fastest purely serial interface for position encoders based on the RS 485 transmission characteristics.

NCT-201 Control System

The new NCT 201 control’s CPU is conveniently located behind the large 19” LCD monitor. The monitor features a user friendly touchscreen for easy operation. If preferred other optional pointing devices (mouse, track ball, touchpad) can be connected using the 4 USB ports provided at the right side of the screen. The CPU features the newest 1.8 GHz Intel® Atom™ low energy consumption microprocessor and therefore does not require external cooling fan. The Windows CE CPU connects to the peripheries via super fast EtherCAT bus, and with one ETHERNET cable the operator panel can be connected to a computer network. The system program of the NCT 201 fits WINDOWS CE operation system perfectly, exploiting it to its full potential, such as its professional file management, computer peripheries management (data storage devices, printers, data input peripheries, pointing devices, etc.), and other services (network, internet, remote machines, picture and video displaying, playing sound files, etc.).

The CNC control and operator’s panel assembly is offered as a stylish closed boxed unit that can be fixed to a pendant, no more sheet metal work is needed. If preferred it can be built in to a front machine panel, as it is customary with CNC control panels. NCT provides its customers with fixtures (built in frame, screws, supporting arm, suspending arm and rotating or pivoting joints) for the professional construction of any installation design.

Components

Op-panel-201

The NCT 201 control can be connected to any custom machine keyboard, it is not necessary to buy the NCT operator panel. The flexible system allows the users to create their own machine interface via the Input/Output PLC lines, in which they can optionally combine the touch screen’s virtual buttons with the custom machine panel’s real buttons. The NCT 201 optional machine operator’s panel matches the monitor module in size, style and color. It is also perfectly compatible with the monitor when they are built-in or on a supporting arm, as they form an integrated system. The NCT 201 operator panel features 20 programmable user buttons besides the standard operating devices by NCT (handwheel, feeding override, jog, mode buttons, emergency stop button, etc.). The transparent button covers pop out on the operator side, allowing for an easy insertion of machine specific titles under them. Every Fanuc size button on the NCT control panel has LED lighting that can be easily seen from every direction.

In the standard version the operator can use the virtual keyboard on the touchscreen monitor for data input. The keyboard image on the monitor only appears and takes up space when it is needed for data input. As it is merely virtual, it is easily adjustable for different languages, which the operator can easily change if needed. The size and placement of the buttons makes the data input very comfortable. The speaker at the bottom of the panel emits a clicking sound when the buttons are touched. In order to protect the touch screen a self-adhesive screen protector foil is used. Since the usage of virtual keyboard does not cause mechanical deformation, they cannot wear out, only the foil can become dull, or scratched, both of which can be solved by replacing the screen protector every once a while.

If the operator prefers a QWERTY keyboard, that can easily be connected via any of the 4 USB ports. The wired or wireless keyboard can be located in a fixed drawer under the NCT control panel and the machine keyboard, in an ergonomically comfortable position. A shelf can also be provided under the keyboard for documents, such as workpiece drawings program prints, etc.. For the wireless keyboard offered by NCT, we also provide foil cover, which can protect the keyboard from moisture and dust ensuring a long service life. Naturally flexible industrial keyboards can be used as well.

Peripheries will be connected to the NCT 201 CPU via EtherCAT (industrial ETHERNET). The peripheries can be NCT IO units, NCT drives, or they can be other standard EtherCAT peripheries from other manufacturers as well (e.g.: BECKHOFF, YASKAVA, ABB, HITACHI, BAUMÜLLER, LENZE, SEW, WAGO, etc.). The “high-speed rail” system is designed the way that behind the EtherCAT connection lead unit different I/O units of different functions and sizes (like railway carriages) can be connected via an LVSD bus and a flat cable. This assembled “train” is mounted on an OMEGA rail, frequently used in the construction of electrical cabinets. Presently 12 types of “carriages” of different functions are offered by us, but we are expanding the selection, and our customers can request custom “carriages” as well.
