You can configure the communication relationships between DP slaves using the
internode communication function, e.g.:
½ "Broadcast principle": One master drive specifies a master setpoint for all slave
drives.
½ "Peer-to-peer principle": A setpoint is forwarded from one drive to the next.
A communication relationship is also referred to as a "channel" or "link".

The MICROMASTER4 has a total of 4 words of receive data (setpoints) and 4
words of transmit data (actual values).
A source-destination relationship can be defined for this type of data word, e.g.
setpoint 1 is sent by DP master; setpoint 2 is sent by an internode-capable slave
and not by the DP master.

A broadcast channel which the DP master and any number of DP slaves can
receive, i.e. a maximum of 4 data words on MICROMASTER4
1XPEHURIUHFHLYHFKDQQHOV
Maximum four, i.e. the four setpoints could come from four different sources on the
PROFIBUS.

½ STEP 7, version 5.1 and later
½ Drive ES SIMATIC V5.1
½ S7 PROFIBUS master system with "Equidistance" capability (clocking)
½ Internode-capable DP slaves as communication partners
(e.g. drives or ET200)
Internode communication is programmed with the SlaveOM in the "Configuration"
screen.
The sequence of configuring operations is described in the documentation for Drive
ES SIMATIC.
