4.16.4.1 General information
The X20DS1828 module is equipped with a HIPERFACE encoder interface. This module can be used to evaluate
encoders installed in motors from other manufacturers as well as encoders for external axes (encoders that scan
any machine movement). The input signals are monitored, making it possible to detect open or shorted lines as
well as encoder supply failures.

HIPERFACE
HIPERFACE is a standard developed by Max Stegmann GmbH (
), which like EnDat incorporates
the advantages of absolute and incremental position measurement while also offering a read/write parameter
memory in the encoder. With absolute position measurement (the absolute position is sampled serially), a homing
procedure is usually not required. Where necessary, a multi-turn encoder should be installed. To save costs, a
single-turn encoder and a reference switch can also be used. In this case, a homing procedure must be carried out.
The incremental process allows the short delay times necessary for position measurement on drives with excep-
tional dynamic properties. With the sinusoidal incremental signal and the fine resolution in the HIPERFACE mod-
ule, a very high positioning resolution is achieved in spite of the moderate signal frequencies used.
NetTime position timestamp
Highly dynamic positioning tasks require not only the position value, but also the exact time at which the position
was determined. The module has a NetTime function for this, which adds a timestamp to the recorded position
with microsecond accuracy.
The module provides the PLC with the position value and timestamp as absolute time value. The NetTime mech-
anisms ensure that the PLC NetTime clock and the local NetTime clock on the module have exactly the same
absolute time at all times.
