Connecting to the Host’s RS-232C Port
The methods for connecting the RS-422A/485 port of the NT631/NT631C and
the RS-232C port of the host are described here. There are the following
methods.
The following discussion is focused on the connection method to OMRON
PLCs (By using the memory link method, a connection can be made to any
arbitrary RS-232 unit). When making a connection to a host other than
OMRON PLCs, refer to the PLC Connection Manual (V042-E1-@) or NT31/
631 Multi Vendor Connection Manual (V060-E1-@).

• Method in which the RS-485 ports of multiple NT631/NT631Cs and the
232C port of the host are connected in a 1:1 connection via an RS-232C/
RS-422A Adapter (page 82).
port of the host are connected in a 1:1 connection via an RS-232C/RS-
422A Adapter (page 82).
RS-232C port of the host are connected in a 1:N connection via an RS-
232C/RS-422A Adapter (page 86).
RS-232C port of the host are connected in a 1:N connection via an RS-
232C/RS-422A Adapter (page 86).
When this method is used, the cable length can be extended up to
500 m.
When this method is used, the cable length can be extended up to
500 m. This connection method can be used only with the NT Link
(1:N) method of type RS-485.
This connection method is used with the RS-422A NT Link (1:N) meth-
od.
This connection method is used with the RS-485 NT Link (1:N) method
(standard or high-speed).
