Example for reading a parameter via MOVILINK
®
The following tables give an example of the structure of the WRITE.request and
READ.response user data for reading an individual parameter via the MOVILINK
®
parameter channel. In this example, the firmware of the MFE fieldbus interface is read.
Positive MOVILINK
®
parameterization response
The table shows the READ.response user data with the positive response data of the
parameter setting request. The parameter value for index 8300 (firmware version) is
returned as an example.
