Host Link Function for Replacing Existing PLCs
Unit Ver. 1.2 or Later
1:N/1:1 setting
1:N protocol A Host Link protocol that
enables a single host to be
connected to a single PLC
(1:1) or to multiple PLCs
(1:N).
In previous Boards/Units, only
the 1:N protocol was sup-
ported.
1:1 protocol A Host Link protocol that
enables a single host to be
connected to a single PLC
only.
1:N Host Link
140
Host computer programs for 1:1 Host Links that have been created using a
C200H/C1000H/C2000H PLC can also be used with CS/CJ-series PLCs by
selecting the 1:1 Host Link protocol. The 1:N/1:1 Host Link setting in the
Setup Area in the DM Area enable selection of 1:1 Host Links.

Remarks
The CS/CJ Series, C200HS/
@
HX/HG/HE(-Z), CPM , and
@
CQM1 Series all support
only 1:N Host Links for the
CPU Unit's built-in port and
Host Link Unit/Serial Commu-
nications Board.
The earlier Serial Communi-
cations Units/Boards support
only 1:N Host Links.
The CVM1/CV Series sup-
ports only 1:N Host Links for
the CPU Unit's built-in port
and Host Link Unit/Serial
Communications Unit/Board.
The C-series Host Link Units
shown here support both 1:1
protocol and 1:N protocol.
