the axis interface), use the bit 1-4 to set the ID, so as to determine the number range of IO
to be expanded.
If the controller itself contains 28 INs and 16 OPs, then the starting address set by
the first extended board should exceed the maximum value of 28. According to below rule,
the dial code should be set to the combination value 1 (binary combination value 0001,
from right to left, dial code 1-4, at this time dial 1 is set to ON, and the others are set to
OFF), the IO number on the expansion board = the expansion board number value + the
initial IO number value, among them, the IOs that are vacant from 29-31 Numbers are not
used. Subsequent extended boards continue to confirm the dial settings according to the
IO points in turn.
The initial digital IO mapping number starts from 16 and increases in multiples of 16.
The distribution of digital IO numbers corresponding to different dial IDs is as follows:
DIP 1-4 combination value
Starting IO number
Ending IO number

The initial IO mapping number of the analog AD starts from 8 and increases in
multiples of 8. The initial IO mapping number of the analog DA starts from 4 and increases
in multiples of 4. The allocation of digital IO numbers corresponding to different dial code
IDs is as follows:
DIP 1-4

Starting AD
