Description
IP Address
Used to select the IP address of the Ethernet driver that will listen to data.
By default, an Ethernet driver in
FactoryTalk Linx
 attempts to listen on all IP addresses assigned to the workstation, and the Ethernet network browse executes a subnet broadcast over all network interface cards associated with the workstation. If you want an Ethernet driver to attempt to listen only on one specific IP address, and if you want the browse that is associated with that driver to broadcast only on that IP address's subnet, then click on that IP address.
Tip:
 The selection of a specific IP address is not compatible with DHCP due to the fact that DHCP may reassign the IP address.
If multiple IP addresses are assigned to a single NIC (Network Interface Card), then any other EtherNet/IP application offering similar configurability could be associated with a different IP address. The workstation would thus appear more than once in the EtherNet/IP browse, with each application displaying independently under its own IP address.
Tip:
 Be careful when using the
Copy from Design to Runtime
 button in the
FactoryTalk Linx
 Communication Setup editor. When a configuration containing an Ethernet driver associated with a specific IP address is applied to a workstation for which that IP address is invalid, the Ethernet driver will not listen on the EtherNet/IP encapsulation ports, and thus will not show up in a browse.
MAC Address
Multiple IP addresses can be assigned to a single NIC.
Listen on EtherNet/IP encapsulated ports
Used to enable or disable the Ethernet driver to listen on the Ethernet/IP UDP and TCP ports, and thus be visible during a browse.
Tip:
  • You must enable this command to receive data from
    ControlLogix
    , controllers via an unsolicited message.
  • Clear the check box to allow another application to acquire the UDP port.
  • The EtherNet/IP Encapsulation Protocol defines a reserved UDP port (number AF12 hexadecimal; number 44818 decimal) which every EtherNet/IP device must support for the device to display in a browse. By default,
    FactoryTalk Linx
     doesn’t listen on this port until the checkbox is selected.
  • Other EtherNet/IP applications (such as
    RSLinx Classic
    ) running on a workstation can also listen on this port, resulting in a race condition: the application that starts first acquires the port, and that application's identity is the one exposed to a browse. Since that application also acquires the matching EtherNet/IP TCP port (also number AF12 hexadecimal; number 44818 decimal), all EtherNet/IP communications will be directed to that application.
