Connection to a PLC by the Host Link (RS-232C Type)
32
PLC model
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.)
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.
