and activate the ethernet interface channel 1
Bring the ECS Slave to Pre-Operational state. TwinCAT writes EoE startup parameter (MAC and IP) in the statechange form Init to Pre-Operational to the ECS Slave. After that EoE is ready.
The example demonstrates the TCP/UDP server and client ability of the socket interface. For the opposite part, any TCP/UDP server respectively client can be used, for example Socket Test shown below.

use the same IP like in TwinCAT
The configuration of the socket interface is done by hSockCtrl[] table in AppSockIf_DemoApplicationFunctions.c. Several instances may be created, thus an amount of combination of TCP/UDP servers and clients can be implemented, the limitation of the instances is given by BACKLOG define, the bigger the BACKLOG, the fewer instances are possible.
