Note 1: Use a CPM2C-CN111 or CS1W-CN114/118 Connecting Cable, CPM1-CIF01
RS-232C Adapter, or CPM1-CIF11 RS-422A Adapter to connect.
2: CPU Units of CVM1/CV-series PLCs without the suffix -EV@ cannot be connected.
The RS-485 interface (2-wire method) provided by NS-series PTs is for connecting to an
OMRON Temperature Controller. Do not connect it to an NS-series PT or PLCs using RS-485.
Settings at the Host
When using the RS-422A type host link method, the settings shown below must be made at
the host (depending on the unit, some of these settings may not be necessary, or settings not
shown here may be necessary).

Note 1: Set the Host Link communications speed (baud rate) to 9600 bps or 19200 bps with
the Communications Setting menu item in the CX-Designer and the System Menu
for the NS-series PT. For details, refer to 1-4 Settings for Host Link.
2: The 1-to-N setting enables using a BCC (Block Check Character). It is not actually
possible to connect more than one NS-series PT in a single Host Link.
The setting methods for each type of unit are described in the following.
