Function Manual
640 Function Manual, 06/2012, 6SL3097-4AB10-0BP4
Links and taps
The links configured in the subscriber (connections to publisher) contain the following
information:
● From which publisher is input data received?
● Which input data are there?
● 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.
Prerequisites and supplementary conditions
The following supplementary conditions should be observed for the "slave-to-slave
communication" function:
● STARTER Version 4.2 or higher
● Drive ES Basic version 5.3 SP3 or higher
● Firmware version 4.3 or higher
● The maximum number of process data per drive can be identified from the value in r2050
– minus the resources that have already been used
● 4 links to publishers
Applications
For example, the following applications can be implemented using the "slave-to-slave
communication" function:
● Axis couplings (this is practical for isochronous mode)
● Specifying binector connections from another slave
