Chapter 5 Using the I/O

Understanding the Profinet
Scanner I/O Image

The terms ‘input’ and ‘output’ are defined from the controller’s point of view.
Therefore, output I/O is data that is produced by the controller and consumed by
the option module. Input I/O is status data that is produced by the option
module and consumed as input by the controller. The I/O image will vary based
on how many of the drive’s 32-bit Datalinks (

Host DL From Net 01-16 and Host

DL To Net 01-16

) are used.

The I/O image can be configured based upon the number of Datalinks required
by the user.

Table 2

shows the I/O image when using all of the 32-bit Datalinks.

(32-bit Logic Command/Status, Reference/Feedback, and Datalinks)

Using Logic Command/
Status

The Logic Command is a 32-bit word of control data produced by the controller
and consumed by the option module. The Logic Status is a 32-bit word of status
data produced by the option module and consumed by the controller.

• Logic Command word is always the first 32-bit word in the output image.
• Logic Status word is always the first 32-bit word in the input image.
