Composition of a process image in the Bus Coupler

An example shows the assignment of input and output channels to the process image. The sample
construction should consist of the following bus - terminal - assemblies:

By default, DeviceNet only supports signal channels that are 16 bits wide. The STATUS/CONTROL BYTE is
not available. This means, for example, that an analog input terminal with 2 channels appears in the process
image with 2 x 16 bits. The images have corresponding differences with respect to byte addresses and
assignments.
