1.3 Basic Functionality
The Ethernet Port has the following main features.
1. T series computer link protocol transmission (slave port)
The host machine can upload or download user programs, execute control commands, and read or
write register data to a T2N on the 10BASE-T LAN using the T series computer link protocol.
This function can be used simply by making basic settings on the Ethernet Port from the T2N;
there is no need to write special user programs for the T2N.
Computer link protocol uses UDP/IP as the transmission protocol.
UDP/IP: User datagram protocol/Internet protocol.
