EIB 700 Series

The EIB 700 series are external evaluationelectronics for precise position
measurement, especially for inspection
stations and multipoint inspection
apparatuses as well as for mobile dataacquisition, e.g. during machine calibration.

The EIB 700 series subdivides the signal
periods of the incremental signals up to4096-fold for measured value generation.
The deviations within one signal period are
reduced by the automatic adjustment of
the sinusoidal incremental signals.

The EIB 700 series are ideal for
applications requiring high-resolution
encoder signals and fast measured-valueacquisition. In addition, Ethernet
transmission enables the use of switchesor hubs for the interconnection of multiple
evaluation units. It is also possible to use
WLAN transmission, for example.

The integrated measured-value memory
enables the EIB 700 series to save typically
250 000 measured values per axis. Internalor external triggers can be used for axisspecific storage of the measured values.

The EIB 700 series are suitable for thefollowing supply voltages:
EIB 741: 100 V AC to 240 V
EIB 742: 24 V DCUp to four HEIDENHAIN encoders can beconnected to the EIB 700 either withsinusoidal incremental signals ( 1 VPP; 11 µAPP) or with EnDat interfaces(EnDat 2.1 and EnDat 2.2).

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

Driver software for Windows, Linux andLabVIEW as well as example programs andthe EIB application software are included in
the items supplied, in order to process themeasured values on the PC. The driver
software enables customers to easily
programming their own applications. In
addition, example programs demonstrate
the capabilities of the EIB 700 series. The
EIB application software serves forcommissioning and demonstrating thecapabilities of the EIB 700 series. This
software is made available in the sourcecode and can serve as a platform for thedevelopment of one’s own applications.
Due to their dimensions, two evaluationelectronics of the EIB 700 fit next to eachother into a 19-inch housing. They occupy
one height unit.

Software
EIB application software

The EIB application software covers twoapplications:
Initial service and demonstration of theEIB 74x• Easy configuration of the settingsrequired to operate the EIB 74x (such as
input interface, data packets, operating
mode, trigger settings, etc.)• Administration of one or more EIB 74xunits• Simple representation of the positionstransmitted by the EIB 74x• Settings can be saved so that different
application projects can be managed
The user’s guide provides moreinformation.

Platform for customer applications
The EIB application software is madeavailable in the source code. Based on thisapplication, customers can quickly realize
their own applications. The application
software was programmed with C++/CLI
and Windows Forms in Visual Studio 2008.
This programming environment is widelyused in technical application programming,but does not necessarily provide state-ofthe-art operating techniques like those inWindows 10, for example. However, thecustomer can adapt the program to othergraphic user interfaces.
