DeviceNet™2组用于PIC18从机与CAN固件

The DeviceNet™ system is an open network standard,
built on the Controller Area Network (CAN), designed
to reduce the cost and time to install industrial devices
while providing compatibility with multiple vendors. The
DeviceNet specification is available from the Open
DeviceNet Vendor Association, Inc. (ODVA). Example
DeviceNet devices might include motor starters,
valves, sensors, displays and more.
The DeviceNet specification covers multiple layers, from
the wiring and protection circuits, up to the software
protocol and application definition (see Figure 1);
however, this application note only focuses on a specific
development of the software known in the specification
as the Predefined Master/Slave Connection Set. To be
even more accurate, this application note only presents
a slave node within the Predefined Connection Set, also
referred to as a Group 2 Slave.
