14-2-1 Overview
14-2 Program-free Communications with
Programmable Terminals
Communications without special communications programming is possible between a CP2E CPU Unit
and a Programmable Terminal (PT) by using the Host Link or 1:N NT Link protocol.
Connect the serial port of the CP2E CPU Unit and PT with Host Link or NT Link (1:N) communication
mode, and connect the CP2E CPU Unit and PT 1:1 as shown below.
z Connectable Programmable Terminals (PTs)
High-speed Links (115,200 bps) can be used with NB-series, NS-series, or NV-series PTs.
Precautions for Correct UsePrecautions for Correct Use
• Communications are not possible for CP2E CPU Units using the 1:1 NT Link protocol. Do not
connect more than one PT to a CP2E CPU Unit even if the 1:N NT Link protocol is used.
• SAP (Smart Active Parts) on NS-series PTs cannot be used for CP2E CPU Units.
