Configuring I/O Links
In the application program, use Move and Block Move instructions to configure the I/O Links in the system by placing the required data in the appropriate %P program references.
Configuration Logic, Example
Use Move instructions to supply the number of I/O Link Interface Modules (1), and the rack location (0), and slot location (5) of that module.

Block Move instructions can supply the data lengths and beginning %I and %Q addresses for six slaves on the link, which is link 1 in this example.

The first Block Move configures the length and beginning %I and %Q addresses of devices 0 and 1. The second Block Move configures devices 2 and 3. The third Block Move configures devices 4 and 5. To simplify programming, IN7 in these Block Moves is not used. If there were more I/O Links, or more devices on link 1, they would be configured in the same manner.
