Connection

4.2 Network Connection

4.2.1 Ethernet Ports

The device has 2 Ethernet ports. If only 1 connection is
required, either port can be used.

4.2.2 Cables

4 4
Suitable cables for PROFINET Module connection:
•
Category 5
•
Category 5e
•
Category 6
•
Category 6e

4.2.3 EMC Precautions

To minimize electromagnetic interference, Ethernet cables
should be separated from motor and mains cables by
200 mm (7.9 in).
The Ethernet cable must cross the motor and mains cables
at an angle of 90°.
≥ 200 mm

4.2.4 Network Establishment

The controller must establish communication directly with
each device before the device can participate in the
network.

4.3 Communication Protocols

LC-RPC Connectionless remote procedure call
DCP Discovery and configuration protocol
LLDP Link layer discovery protocol
MRP Media redundancy protocol
RTC Real-time cyclic protocol; Class 1 and 2 (unsynchronized),
Class 3 (synchronized)
SNMP Simple network management protocol
Table 4.2 PROFINET-supported Protocols
DHCP Dynamic host configuration protocol
MCR Multicast communication relation
RTA Real-time acyclic protocol
Flexible Real-time cyclic protocol; Class 2
RT_CLASS_2 synchronized
RT_CLASS_UDP Unsynchronized cross-subnet communi-
cation between different subnets
Table 4.3 Protocols not Supported by PROFINET
The maximum data length for input and output data is 256
bytes each.

4.4 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 chapter 5.1 Ethernet Device Configuration Tool)
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.
