Notes:
NET 1:
Ethernet interface cannot be used for programming and debugging Nexto Series CPUs.
Gratuitous ARP:
NET1 Ethernet interface sends spontaneously ARP type packets in broadcast, informing its IP and MAC
address for all devices interconnected to the network. These packets are sent during the download of a new application by the
MasterTool IEC XE software and in the startup of a NX5000 interface. 5 ARP commands are sent, with an initial interval of 200
ms, doubling the interval between every new triggered command, totalizing 3 s. Example: First trigger occurs at time 0, the
second one at 200 ms, the third one at 600 ms and so forth until the fifth trigger occurs at time 3 s.
