Connecting to the RS-232C Port at the Host
Host Types and Settings
Reference:
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-@) or NT31/
631 Multi Vendor Connection Manual (V060-E1-@).
Direct Connection Between The RS-232C Ports Using an RS-232C Cable
(page 73)
This is the easiest connection method. Depending on the host to which the
connection is to be made, it may be possible to use OMRON cables with con-
nectors.
The CS/CJ-series CPU Unit cannot be connected with the 1:1 connection NT
link method. 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 64) or
Using the High-speed NT Link (1:N) Method (page 69).
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/CJ-series or CQM1H PLCs, the host link method can be used by
installing a Serial Communications Board/Unit. In addition, some C200HX/
HG/HE(-Z)E CPU Units can be connected in the host link method by installing
a Communications Board.
Check the model and series of the PLC, the type of installed Serial Communi-
cations Board, Serial Communications Unit, or Host Link Unit before making a
connection.
