FactoryTalk Linx and FactoryTalk Logix Echo binding to port 44818

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 browse. By default,

FactoryTalk Linx

doesn't listen on this port until the

Listen on EtherNet/IP encapsulated ports

checkbox is selected.

FactoryTalk Edge Gateway

running on a workstation can also listen on this port, resulting in a race condition: the application that starts first aquires the port, and that application's identity is the one exposed to a browse. Since the

FactoryTalk Edge Gateway

application also acquires the matching EtherNet/IP TCP port (number AF12 hexadecimal; number 44818 decimal), all EtherNet/IP communications will be directed to

FactoryTalk Edge Gateway

.

This port is occupied by

FactoryTalk Logix Echo

also. So, when the user uses the

FactoryTalk Logix Echo

to simulate RA controllers and selects

Smart Detection

then the

Auto device and model

does not work and no devices are discovered. Workaround for this is to open the

Windows Task Manager

, then in the

Processes

tab , select the

FactoryTalk Logix Echo

and Click

End Task

.

Perform the following steps to prevent FactoryTalk Linx from binding to port 44818:
