4.2.8 Profibus DP Cyclic Data

The cyclic data is a fast process data transfer between the Profibus DP master and the slave, which occurs once in
every DP cycle. EntelliPro ES is a modular device supporting up to 144 bytes of input data and 18 bytes of output data.
Modules define a block size of input and output data to be read by the master, starting from offset zero. During the
network configuration session, modules with varying sizes of input data are provided in the GSD file.
The following table shows the EntelliPro ES cyclic input and output data provided in the GSD file. Refer to section
4.2.10 for an example of master configuration.

4.2.9 Diagnostic Data

EntelliPro ES supports both slave mandatory – 6-bytes system wide standardized – and slave specific extended
diagnostic data. The table below shows the system standard diagnostic 6-bytes.
