3.4 Backplane Device Driver
The backplane device driver performs CIP messaging over the CompactLogix backplane
using the Midrange ASIC. The user application interfaces with the backplane device driver
through the CIP API library. The backplane device driver for the MVI69E-LDM module is
libocxbpeng.so . The driver implements the following components and objects:
All data exchange between the application and the backplane occurs through the Assembly
Object, using functions provided by the CIP API. The API includes functions to register or
unregister the object, accept or deny Class 1 schedule connections requests, access
scheduled connection data, and service unscheduled messages.
