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.
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
● Firmware as of Version 1.2
● 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
For example, the following applications can be implemented using the "direct data
exchange" function:
● Axis couplings
● Specifying binector connections from another slave
