Communicate with Devices on a DeviceNet Network Appendix A
Example: SoftLogix
Controller and DeviceNet I/O
In this example, one SoftLogix controller controls I/O modules through a
1784-PCIDS communication card.
This example has a SoftLogix controller controlling four DeviceNet devices. The
controller automatically creates a rack-optimized connection for the I/O data.
The tag name for the rack-optimized array tag is based on the slot number of the
1784-PCIDS card. For example, if you install the 1784-PCIDS card in slot 3 of
the controller, the software automatically creates Local:3:I and Local:3:O
data structures.
