EtherNet/IP Communications Module

For example, an image that uses 32-bit words for Reference and

four Datalinks would change the I/O image in figure 6.1 as follows:

An image that uses a 16-bit Reference and 32-bit Datalinks would

change the I/O image in figure 6.1 as follows:

As another example, figure 6.2 illustrates an I/O image that does

not use all of the I/O data. Only the Logic Command/Reference and

Datalink B are enabled. In this example, the reference is a 32-bit

word, and Datalinks are 16-bit words.
