Subscriber
The subscribers evaluate the broadcast telegrams sent from the publishers, and use the
data which has been received as setpoints. These setpoints of the publisher are used in
addition to the setpoints received from the master, corresponding to the configured telegram
structure (p0922).
Links and taps
The links configured in the subscriber (connections to publisher) contain the following
information:
● From which publisher is the input data received?
● What is the content of the input data?
● Where are the additional setpoints received?
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 setpoint via a tap.
Links are possible on the drive unit itself. This internal link corresponds, as far as the timing
is concerned, to a link via PROFIBUS.
Requirements
The following requirements should be observed for the "direct data exchange" function:
● STARTER as of Version 4.2
● Configuration:
– Drive ES Basic, Drive ES SIMATIC or Drive ES PCS7 as of Version 5.3 SP3
– Alternatively using a GSD file
● The maximum number of process data per drive can be identified from the value in r2050
– minus the resources that have already been used
● A maximum of 16 links to publishers
Applications
For example, the following applications can be implemented using the "direct data
exchange" function:
● Specifying binector connections from another slave
