Subscriber
The subscribers evaluate the broadcast telegrams, sent from the publishers, 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
(p0922).
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 do the additional setpoints come in?
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 to the device itself. This means, e.g. for a Double Motor 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.
Prerequisites and supplementary conditions
The following supplementary conditions should be observed for the "slave-to-slave
communication" function:
● Drive ES Basic V5.3 SP3 or higher
● Firmware version V4.3 or higher
● Number of process data, max. per drive
● Number of links to publishers
● Number of taps per link
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
