Rockwell Automation 1203-GK5 DeviceNet Communications Module FRN 1.xxx-3.xxx - Manual (Page 62)

5-2 Creating a Ladder Logic Program
About Ladder Logic Programs A PLC or SLC ladder logic program lets you control the drive and the
messaging from the PLC or SLC on the DeviceNet network. Figure
5.1 shows how the I/O image table for a DeviceNet scanner relates to
the drive when a 1203-GK5 module or 1336-GM5 board is used.
Important: Figure 5.1 shows all datalinks enabled. Users must
enable the desired datalinks in the adapter and connected product.

Example Ladder Logic Programs The following are example ladder logic programs. They can be used
for a 1305, 1336 PLUS, or 1336 PLUS II drive.
Important: Different SCANport products have different Logic
Command, Logic Status, Reference and Feedback I/O interpretations.
Refer to your product manual for specific I/O definitions.
