System Configuration
1-2-5 One-to-one NT Link Communications

1-2-6 CompoBus/S I/O Link Connections

SYSMAC CS-series PC
Using the NT Link, the CPM1A PC can connected to the Programmable Termi-
nal (NT Link Interface) through an RS-232C Adapter.
OMRON Programmable Terminal
Name
RS-232C Adapter Converts to peripheral port-level
communications.
A CompoBus/S I/O Link can be used to create an I/O link (remote I/O) of 8 input
points and 8 output points with a CompoBus/S Master Unit or SRM1 PC. The
connection is made through a CompoBus/S I/O Link Unit.
From the standpoint of the CPM1A CPU Unit, the area allocated to the Compo-
Bus/S I/O Link Unit can be treated just like the area allocated to an Expansion I/O
Unit. The difference is that the bits are not actual I/O points, but I/O bits in the
Master Unit.

Cables
Use special flat cable, VCTF 2-core cable, or VCTF 4-core cable. Do not com-
bine different types of cable in the same system.
