Connections to Serial Communications Option Boards
Connection Methods
Communications Modes and Ports
The following table shows the relationship between the communications ports and the communications modes
for the Serial Communications Option Boards.
Note
(1) The NT-AL001 Link Adapter can be used to convert between RS-232C and RS-422A/485 to enable
1:N communications.
(2) Use 4-wire connections between Link Adapters.
Models of Serial Communications Option Board
Note
The CP1W-CIF11 is a non-isolated board, so the maximum transmission distance is 50 m. For distances
over 50 m, use the RS-232C port on the CP1W-CIF01 and then connect through the NT-AL001 Link
Adapter, which is isolated. Doing so will enable a maximum transmission distance of 500 m.
Reducing Electrical Noise for External Wiring
Observe the following precautions when wiring communications cables, PLC power lines, and high-power
lines. When multi-conductor signal cable is being used, avoid using I/O wires and other control wires in the
same cable.
• If wiring racks are running in parallel, allow at least 300 mm between the racks.
