written to that output, not its present value. For this reason, the binary outputs are not
typically mapped to class 0.
Communication modes
The common DNP 3.0 communication modes are:
• Polled static mode, meaning that the master polls for class 0 or static data only
• Polled report by exception mode, where the Master polls for change events (class
1,2,3) and occasionally makes integrity polls (class 1, 2, 3, 0)
2.2 Documentation
