This section provides details on the networks for hosts that can be used with NS-series PTs.
2-1-1 Communications Types and Connection Methods
• Communications Ports and Methods
All NS-series PTs have two serial ports each. The NS15-TX01@-V2, NS12-TS01(B)-V1/-V2,
NS10-TV01(B)-V1/-V2, NS8-TV@1(B)-V1/-V2, NS5-SQ01(B)-V1, NS5-SQ@1(B)-V2, NS5-
TQ@1(B), and NS5-MQ@1(B)-V2 each have one Ethernet interface.
A Controller Link Interface Unit can also be mounted to the NS12-TS0@(B)-V1 or NS10-
TV0@(B)-V1 to enable Controller Link communications. These communications ports and in-
terfaces can be used for the communications methods shown in the following table.
Communications ports Supported communications methods
Serial port A
1:1 NT Link
1:N NT Links (See note 1.)
For connecting the CX-Designer and for Bar Code Reader input.
Serial port B (See notes 2
and 4.)
1:1 NT Link
1:N NT Links (See note 1.)
For connecting the CX-Designer and for Bar Code Reader input.
Ethernet interface
FINS communications
EtherNet/IP
For connecting the CX-Designer.

Note 1: A 1:N NT Link can be set for either normal or high-speed communications.
Note 2: With the NS5, EXP. (Expansion) I/F on the Comm Tab Page in the System Menu settings can
be set to use a communications port in the expansion interface connector. The expansion in-
terface, however, is a future expansion, which cannot yet be used. Always use the serial port
B connector. Communications will not be possible on serial port B if the expansion interface is
selected in the System Menu settings.
Note 3: Controller Link Interface Units are compatible only with the NS15, NS12 and NS10.
Note 4: With the NS15, the type of communications (RS-232C or RS-422A) can be selected by setting
the DIP switch.
The following table shows the possible combinations of communications methods when se-
rial ports A and B are connected to the host at the same time.
Using serial ports A and B at the same time Supported/not supported
1:1 NT Link + 1:1 NT Link Supported
1:1 NT Link + 1:N NT Links Supported
1:N NT Links + 1:N NT Links Supported
• Converting Communications Type Using RS-232C/RS-422A Converter
OMRON’s NS-AL002 RS-232C/RS-422A Converter can be used to convert the communica-
tions type between RS-232C and RS-422A.
• Communications Type and Connection Method Combinations
The following table shows the possible connection methods for each communications type.
