7-4 Using Multi-Drive Mode
The terms input and output are defined from the scanner’s point of view.
Therefore, Output I/O is data that is output from the scanner and
consumed by the EtherNet/IP adapter. Input I/O is status data that is
produced by the adapter and consumed as input by the scanner. The I/O
image table will vary based on the:
Configuration of the Operating Mode Switch (SW1) on the adapter
and Parameter 22 - [DSI I/O Cfg]. The image table always uses
consecutive words starting at word 0.
Figure 7.5
illustrates the Multi-Drive I/O image with 16-bit words.
Figure 7.5 Multi-Drive Example of I/O Image
Note: If a daisy-chained drive is disconnected from the RS-485 (DSI)
network or powered down, the Logic Status and Feedback words for the
affected drive will be set to 0.
