In the same manner, this 16-bit Analog Input Object File has bit 1/bit 0 of B36:0,
B36:1 and B36:2 configured to 0/1, 1/0 and 1/1 respectively. The event for the
index 0 of 16-bit Analog Input Object are generated as a Class 1 event, the event
for the index 1 as a Class 2 event, and the event for the index 2 as a Class 3
event, if there are any changes for the points (N14:0, N14:1 or N14:2). For any
other 16-bit Analog Input points, the events will not be generated.
