5.4 Cyclic data transmission
DP-V0 describes the cyclic data transmission in the PROFIBUS
®
.
5.4.1 Overview of the data objects
The data objects are summarised into modules and their configura‐
tion identifier – see following table. The configuration identifier
allows modules to be excluded from cyclic data transmission
during configuration to avoid unnecessarily burdening cyclic data
transmission.
