1:1 NT Links
The NT Link communications protocol was developed to enable high-speed
communications between PLC and Programmable Terminals (PTs). There are
two communications modes supported by the NT Link protocol: 1:1 NT Links,
in which one PLC is connected to one PT, and 1:N NT Links, in which one
PLC is connected to more than one PT.
Connections
With the NT Link protocol, the PLC auto-
matically responds to commands sent
from the PT, so no communications pro-
gramming is required in the CP1L.
