7.4 Theory of Operation
The DeviceNet scanner module provides a memory image of the nodes (slaves)
connected to a DeviceNet network. It is this memory image that is controlled by your
LDO created in PiCPro. The module’s on-board processor continually transfers data
between this memory image and the actual DeviceNet nodes.
