1:N NT Links
In the CP Series, communications are possible with PTs (Programmable Ter-
minals) using NT Links in 1:N mode.
Note
Communications are not possible using the 1:1-mode NT Link protocol.
High-speed NT Links are possible in addition to the previous standard NT
Links by using the PT system menu and the following PLC Setup. High-speed
NT Links are possible, however, only with NS-series PTs or with the NT31(C)-
V2 or NT631(C)-V2 PTs.
