Heidenhain Corp.'sEIB 741 is a network-capable measuring solution that removes the requirement of
a PC interface card that is usually necessary when connecting measurement
apparatus to an industrial PC or laptop.
A maximum of four Heidenhain encoders, either with sinusoidal incremental signals (1Vpp) or with EnDat
interfaces (EnDat 2.1 and EnDat 2.1), can be connected to the EIB 741. This
external interface box subdivides the periods of the incremental signals up to
4096-fold for measured-value generation. The integrated measured-value memory
enables the EIB 741 to save up to 250,000 measured values per axis. Internal or
external triggers can be used for axis-specific storage of the measured values.
A standard Ethernet interface using TCP/IP or UDP
communication is standard for data output. This permits the direct connection
to the PC or laptop. 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 is included
in the items supplied in order to process the measured values on the PC. The
driver software facilitates programming as well as includes programming
examples demonstrating the performance range of the EIB 741.
Two EIB 741 interface boxes can fit next to each other
within a standard 19-inch housing, occupying one height unit. Multiple boxes
can also be daisy-chained in other configurations.
The EIB 741
is useful for inspection stations and multipoint inspection apparatuses as well
as for mobile data acquisition, such as in machine inspection and
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
