1.1 Features
1.1 Features
Two methods of wiring may be employed, depending on the application: standard wiring
or loop wiring.
Example: Standard wiring
In this method, wiring is done from the control section using
an S−LINK exclusive flat cable and an end hook−up connector
is connected at the end of the main cable. The maximum cable
length is 200 meters (400 meters if a booster is used).

Example: Loop wiring
The S−LINK exclusive flat cable from is run from the controller,
and the end is connected back to the controller. The loop can
have a maximum length of 200 meters. The end connector is
connected at approximately the mid−point of the loop (the
position furthest from the S−LINK unit). Even if the main
signal/power line is broken at one point, the system does not
go down and signal transmission continues.

1.1 Features
•A built−in S−LINK controller is provided for coupling directly to the
S−LINK. This enables wiring for expansion inputs and outputs
points to be neat and efficient.
•The user may select combinations offering up to a total of 128
inputs and outputs.
•For the CPU with S−LINK, two internal S−LINK controllers are
provided, and two input/output channels (128 points x 2) can be
used.
•The inputs and outputs are handled by the program just like
ordinary ones.
•The S−LINK system can be easily monitored by reading shared
memory data.
•A broad range of peripheral devices for the S−LINK enable easy
system configuration.
