6.3.1.7 Network

This chapter includes all object types needed to represent the physical network topology of a PROFINET network.

Figure 18 shows an example which illustrates the relations between network objects of a single port PROFINET device and a 4 port Ethernet switch.

The Ethernet interface, ports and cables are represented by objects in the address space. This Ethernet objects relate to each other by CommLinkTo references. This enables the OPC UA Server to represent the physical network topology of the PROFINET network.

6.3.1.7.1 IPnInterfaceType

The BrowseName of an interface object instance shall be the PROFINET interface id with the range 1..16 in decimal number string format.

The NameOfStation variable may be set with the SetNameOfStation method. Nevertheless, the variable itself shall always be read-only.

The CommLinkTo reference points to an EthernetInterfaceType object instance. An object of the IPv4FeatureType must be implemented in this EthernetInterfaceType object instance.

Mapping to PROFINET properties:

6.3.1.7.1.1 SetNameOfStation Method

This optional method writes the NameOfStation remanent to the PROFINET device and sets the NameOfStation variable accordingly.

Signature

	SetNameOfStation (
		[in]	String NameOfStation
		);
	

Method Result Codes

6.3.1.7.2 PnInterfaceContainerType

The <Interfaces> shall have the references defined in Table 53 and Table 54.

6.3.1.7.3 PnPortType

The PnPortType Object Type includes the port specific data of a port submodule.

A PnRealSubmoduleType instance representing a port submodule has an IsPnPort reference to a PnPortType object instance.

Mapping to PROFINET properties:

6.3.1.7.4 PnPortContainerType

6.3.1.7.5 PnPortStatisticType

The port statistic counters can be read from a PROFINET device with the Read PD Port Statistic PROFINET service.

6.3.1.7.6 NetworkComponentType

The NetworkComponentType is the abstract base ObjectType for different types of network components.

The Enabled variable indicates if the network component is activated (Enabled == True) or deactivated (Enabled == False).

6.3.1.7.7 EthernetInterfaceType

The EthernetInterfaceType is used to represent Ethernet network interfaces.

The MacAddress Variable is read only and represents the unique Layer2 source MAC address of the related interface.

Mapping to PROFINET properties:

6.3.1.7.8 EthernetPortType

The EthernetPortType is used to represent Ethernet ports.

The PhysAddress Variable is read only and contains a MAC address representing the Port.

6.3.1.7.9 NetworkComponentFeatureType

The NetworkComponentFeatureType is the abstract base ObjectType for different types of network components.

6.3.1.7.10 IPv4FeatureType

The IPv4FeatureType is used to represent IPv4 settings of a network interface.

Mapping to PROFINET properties:

The IpAddress Variable describes the IPv4 address on the interface.

The SubnetMask Variable describes the IPv4 Subnet mask on the interface.

The DefaultGateway Variable describes the IPv4 address of the default gateway.

The DhcpEnabled Variable specifies whether the DHCPv4 Client functionality for this interface is enabled.
