DHCP Dynamic host configuration protocol
MCR Multicast communication relation
RTA Real-time acyclic protocol
Flexible
RT_CLASS_2
Real-time cyclic protocol; Class 2 synchronised
RT_CLASS_UDP Unsynchronised cross-subnet communication between different subnets
The maximum data length for input and output data is 256 bytes each.
3.5 Addressing
Each device in a network is addressed using a MAC address and an IP address, and can be assigned a
symbolic name associated with the MAC address.
•The module must be assigned a static IP address (see Ethernet Device Configuration Tool on page
8), or can be assigned an IP address by the master via DCP. The Profinet Module does not support
DHCP addressing.
•The symbolic name is optional and must be configured within the device.
•The MAC address is fixed within the device and is printed on a label on the front of the module.

6. Packet Structures
NOTE
Some soft starters do not support some functions.
The following functions are only available with Digistart D3 soft starters:
parameter management, dual motor control, digital inputs, jog, current measurement in
amperes, power information, warnings.
6.1 Ensuring Safe and Successful Control
Data written to the Profinet Module will remain in its registers until the data is overwritten or the module is
reinitialised. The Profinet Module will not transfer successive duplicate commands to the soft starter.
NOTE
If the soft starter is started via fieldbus communications but stopped via the keypad or a remote
input, an identical start command cannot be used to restart the starter.
In order to operate safely and successfully in an environment where the soft starter may also be
controlled via the keypad or the remote inputs (as well as via fieldbus communications), a control
command should be immediately followed by a status query to confirm the command has been actioned.
6.2 Control Commands (Write Only)

7. Network Design
The Profinet Module supports star, line and ring topologies.
7.1 Star Topology
In a star network, all controllers and devices connect to a central network switch.
Figure 7-1 Star network topology
14697.A
7.2 Line Topology
In a line network, the controller connects directly to one port of the first Profinet Module. The second
Ethernet port of the Profinet Module connects to another module, which in turn connects to another
module until all devices are connected.

14695.A
NOTE
The Profinet Module has an integrated switch to allow data to pass through in line topology. The
Profinet Module must be receiving control power from the soft starter for the switch to operate.
NOTE
If the connection between two devices is interrupted, the controller cannot communicate with
devices after the interruption point.
NOTE
Each connection adds a delay to communication with the next module.
The maximum number of devices in a line network is 32. Exceeding this number may reduce
the reliability of the network.

7.3 Ring Topology
In a ring topology network, the controller connects to the first Profinet Module, via a network switch. The
second Ethernet port of the Profinet Module connects to another module, which in turn connects to
another module until all devices are connected. The final module connects back to the switch.

NOTE
The network switch must support loss of line detection.
7.4 Combined Topologies
A single network can include both star and line components.
