Heidenhain: Evaluation Electronics EIB700 (EIB741 & EIB742)

Evaluation Electronics for Metrological Applications

Evaluation Electronics for metrological applications offer numerous functions for measured data acquisition and statistical evaluation of measured values.

QUADRA-CHEK evaluation electronics for profile projectors, measuring microscopes, 2-D and video measuring machines as well as CMMs measure points on 2-D contours, depending on the version either automatically or manually by crosshairs, by optical edge detection or by video camera with real-time display of the live image and integrated image processing. For 3-D contours, such as planes, cylinders, cones and spheres, the measurement points are saved by probing with a touch probe.

In the optional CNC version, they also operate as full-fledged controls for axis positioning and can automatically execute measuring programs.

EIB 700 | The evaluation unit with measured-value memory

The EIB 700 evaluation electronics feature connections for four axes. They are ideal for precise position measurement in particular for inspection stations and multipoint inspection apparatuses as well as for mobile data acquisition, such as in machine calibration.

The EIB 700 series is ideal for applications requiring high-resolution encoder signals and fast measured-value acquisition. Ethernet transmission also enables you to use switches or hubs for connecting more than one EIB. It is also possible to use WLAN transmission, for example.

Execution

The EIB 700 features a bench-top housing. With an accessory mounting bracket it can also be easily built into a 19-inch housing. It is designed for the following voltage supplies:

Functions

The EIB 700 subdivides the periods of the incremental signals up to 4096-fold for measured-value generation. The deviations within one signal period are automatically reduced by adjustment of the sinusoidal incremental signals.

The integrated measured-value memory enables the EIB 700 series to save typically 250 000 measured values per axis. Internal or external triggers can be used for axis specific storage of the measured values. The interval counter permits position dependent triggering in connection with an incremental encoder on axis 1. In addition, the signals of axis 1 are interpolated and forwarded to a position counter. Triggering pulses are generated either at a certain position or equidistantly in adjustable intervals. They begin after an adjustable start position has been traversed and continue in both counting directions. The trigger pulses can be used for triggering further EIB internal axes or also over a trigger output.

Data Interface

A standard Ethernet interface using TCP/IP or UDP communication is available for data output. This permits direct connection to a PC, laptop or industrial PC. The type of measured-value transfer can be selected through the operating mode (transfer of individual values, block transfer, or transfer upon software request).

Driver software for Windows, Linux and LabVIEW as well as example programs and the EIB application software are included in the items supplied, in order to process the measured values on the PC. The driver software enables customers to easily program their own applications. In addition, example programs demonstrate the capabilities of the EIB 700 series. The EIB application software serves for commissioning and demonstrating the capabilities of the EIB 700 series. This software is made available as source code and can serve as a platform for the development of one’s own applications.

The range of features can be enhanced by updating the firmware.
