1.4 Basic Functionality
(2) T series/PC link protocol transmission
1
The S controller can use the T series/PC link protocol to read or write register data on
another S controller on the 10BASE5/2 LAN or to the PROSEC-T3H/T2N.
The S controller user programs for reading and writing are necessary to use the host
functions.
Only the basic EN311 settings performed from the T3H are required to use the slave
functions, and no special user programs are required on the T3H.
PC link protocol transmission uses UDP/IP as the transmission protocol.
UDP/IP: User Datagram Protocol/Internet Protocol.
