The method for connecting between the RS-232C port of the PT and the
RS-232C port of the host is as follows.
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-j) or NT31/631 Multi Vendor
Connection Manual (V060-E1-j).
Direct Connection Between The RS-232C Ports Using an RS-232C Cable
(Page 109)
This is the easiest connection method. Depending on the host to which the con-
nection is to be made, it may be possible to use OMRON cables with connectors.

od. Use the 1:N connection NT link method instead to make the 1:1 connection.
For details, refer to Using the NT Link (1:N) Method (page 70) or Using the High-
speed NT Link (1:N) Method (page 73).
The types of host that can be connected to a PT by using the RS-232C ports of
both units, and the settings to be made at the host, are described here.
Some models and series of OMRON PLCs have the host link function built in.
In the CS-series or CQM1H PLCs, the host link method can be used by installing
a Serial Communication Board. In addition, some C200HX/HG/HE(-Z)E have
an integral CPU that can be connected in the host link method by installing a
Communication Board.
Check the model and series of the PLC, the type of installed Serial Communica-
tion Board, Serial Communication Unit, or Host Link Unit before making a con-
nection.
