4.5 Application Object (Class ID:0x64)
Application objects are the interfaces between an application and the
DeviceNet Layer. The attributes of application Objects contain the data for the
application, which are accessed and exchanged via DeviceNet. DeviceNet
accesses application data by invoking read and write functions. These
functions need to be provided by an Application Object. DeviceNet provides
Get_Attribute_Single and Set_ Attribute_Single to read and write I-7K/I-87K IO
modules.
