5-6: CAN communication speed, corresponding value is 0-3, four different speeds are
optional.
7: special functions reserved
when bit 7 is dialed as ON, front 6-bit take effect, when OFF, front 6-bit don't take effect).
8: 120 ohm resistor, dial ON that means a 120 ohm resistor is connected between
CANL and CANH.
Use CANIO_ADDRESS to configure CAN address and CAN communication speed,
CAN ID address corresponds to expansion IO No. range. The IO numbers of the entire
control system cannot be repeated, and existed numbers must be avoided when mapping
resources. And the DIP switch must be dialed well before power-on, if re-dial after power-
on, it is invalid. It needs to be powered on again to take effect.
Dial 1-4 to select the CAN address, and the controller sets the IO number range of the
corresponding expansion module according to the CAN DIP address. When each is dialed
as OFF, the corresponding value is 0, when it is ON , it corresponds to a value of 1, and the
address combination value = dial 4 × 8 + dial code 3 × 4 + dial code 2 × 2+ dial code
1.
The distribution of digital IO numbers corresponding to different dial IDs is as follows:
