ControlLogix w/1769-ADN DeviceNet
Example Ladder Program
This chapter provides an example of a ControlLogix controller and
1769-ADN Remote DeviceNet adapter system used with a 1769-SM2
module in Single mode.
Important: When the 1769-SM2 module is used with the 1769-ADN,
the Configuration Mode switch (SW1) must be set to the
“Controller” position (default). See
Chapter 2 for
information on Configuration Mode switch settings.
The 1769-SM2 module can be operated in Multi-Drive mode when used
in a 1769-ADN system (example not provided). However, explicit
messaging and Modbus RTU Master operation CANNOT be used in
Single or Multi-Drive mode because, at the time of publication, the ADN
does NOT support messaging.
The ladder example provided in this section is based on a 1769-SM2
module in slot 1 with one PowerFlex 4/40 drive connected to each
channel (
Figure 8.1 ). The ladder example demonstrates the following
functionality for each channel:
•
Send a Logic Command to control the drive (for example, start, stop).
•
Send a Reference to the drive and receive Feedback from the drive.
•
Receive Logic Status information from the drive.
