Subscribers The subscribers evaluate the broadcast telegrams, sent from the pu-
blishers, and use the data which has been received as setpoints.
The setpoints are used, in addition to the setpoints received from the
master, corresponding to the configured telegram structure (P0915).
Links and taps The links configured in the subscriber (connection to publisher) contain
the following information:
S
S
S
Several taps are possible within a link. Several input data or input data
areas, which are not associated with one another, can be used as set-
point via a tap.
Links are possible to the device itself. This means, e.g. that for a two–
axis module, data can be transferred from drive A to B. This internal
link corresponds, as far as the timing is concerned, to a link via
PROFIBUS.
