Integration in a PROFINET-network
The force measuring amplifiers of the EMGZ490A series were design to work in an
PROFINET-network whereas the amplifier acts as an IO-device (Slave) and die IO-
Controller (or PLC) as a master.
5.1
PROFINET Interface
PROFINET RT is supported. The corresponding communication profile will be selected by
the IO-controller (Master) via GSD. The EMGZ490A transmits the feedback value in Digit
and the Status/Error information Byte. In addition parameters like Offset feedback,
Gain feedback, Filter feedback, Filter analogue output and Scaling of the output can be
set.
