Programmable Terminal
Data can be exchanged
with PTs without using a
communications program
in the CPU Unit.
Note
Only one PT can be
connected when
using a 1:N NT
Link. It is not possi-
ble to connect two
PTs.

instructions are executed
in the ladder program in
the CPU Unit to transmit
data from the transmis-
sion port or read data in
the reception port.
