2. T series/PC link protocol transmission
The T2N can use the T series/PC link protocol to read or write register data on another T2N on the
10BASE-T LAN.
While T2N user programs for reading and writing are necessary to use the host functions, only the
basic Ethernet Port settings performed from the T2N are required to use the slave functions, and no
special user programs are required on the T2N.
PC link protocol transmission uses UDP/IP as the transmission protocol.
