Connection to a PLC by the Host Link (RS-232C Type)
Section 2-4
PLC Setup Settings
When connecting to a C200HS, C200HX/HG/HE(-Z)E, CPM1, CPM2A,
CPM2C, CQM1, or CQM1H CPU Unit, or SRM1, set the following communi-
cation conditions for the PLC Setup.
*1 Set the Host Link baud rate at 9,600 bps or 19,200 bps with the memory
switch at the NT11. For details, refer to Settings the Host Link Method
(page 74).
Set the PLC Setup settings directly from a Programming Device (e.g., the CX-
Programmer Support Software).
For details on operations relating to the PLC Setup, refer to the manual for the
PLC which is used.
The PLC Setup area word addresses and settings to be made depending on
the Unit and port to which the connection is made are shown below.
CPM2A, CPM2C, CQM1H, or SRM1: Peripheral port connection
CPM2A, SRM1 • Connect to the CPU Unit’s built-in RS-232C port.
• Connect to the peripheral port through a CPM1-CIF01 RS-
232C Adapter.
CPM2C Connect to the CPU Unit’s RS-232C port or the peripheral
port through a Connecting Cable (CPM2C-CN111, CS1W-
CN118, or CS1W-CN114).
(The CPM2C-CN111 splits the Unit’s Communication Port
into a RS-232C port and a peripheral port. A CPM1-CIF01
RS-232C Adapter is also required to connect to this periph-
eral port.)
