CPU Units of CVM1/CV-series PLCs without the suffix -EV@ cannot be
connected.
CS/CJ-series CPU Units cannot be connected with the 1:1 connection NT link
method. Use the 1:N connection NT link method (standard or high-speed)
instead to make the 1:1 connection. For details, refer to Using the NT Link
(1:N) Method (page 65) or Using the High-speed NT Link (1:N) Method
(page 70).
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
PLC Setup Area Settings
Write the PLC Setup area (data memory) settings directly from a Program-
ming Device (e.g. CX-Programmer) in accordance with the host model and
port.
