Connection to a PLC by the NT Link (RS-232C Type)
Section 2-6
Reference CS/CJ-series CPU Unit cannot be connected with the 1:1 connection NT link
method. Use the Host Link method (up to 115,200 bps).
Settings at The Host
The setting methods for each Unit are as follows:
Connecting to a C-series C200HS, C200HX/HG/HE(-Z)E, CPM1, CPM2A,
CPM2C, CQM1, CQM1H, or SRM1
PLC Setup Settings
Write the PLC Setup (in the DM Area) settings directly from a Programming
Device (e.g., SYSMAC Support Software) in accordance with the host model
and port.
*1 RS-232C port of the Communication Board
*2 RS-232C port of the Serial Communications Board
For details on operations relating to the PLC Setup, refer to the manual for the
PLC that is used.
Connecting to a CPM2C
The CPM2C PLCs do not have the same kind of port connectors found on CS/
CJ-series PLCs. The CPM2C’s communication port handles both RS-232C
and peripheral port connections, which are divided internally. Therefore, when
using the CPM2C, it is necessary to select RS-232C or peripheral port con-
nections, according to the kind of cable and port (on the cable) used, as
shown in the following table. Refer to the
CPM2C Operation Manual for more
details.
