get_digital_inputs(bit_list)
Features
This function reads the signals from multiple digital contact points of the controller. The digital signals of the contact points defined in bit_list are input at one.

Example
# input contacts: No. 1=OFF, No. 2=OFF, No. 3=ON, and No. 4=ON
res = get_digital_inputs(bit_list=[1,2,3,4])
# res expected value = 0b1100 (binary number), 12 (decimal number), or 0x0C (hexadecimal number)
# input contacts: No. 5=ON, No. 6=ON, No. 7=OFF, and No. 8=ON
res = get_digital_inputs([5,6,7,8])
# res expected value = 0b1011 (binary number), 11 (decimal number), or 0x0B (hexadecimal number)

get_digital_inputs(bit_start, bit_end)
Features
This function reads multiple signals at once from the digital input start contact point (start_index) to the end contact point (end_index) of the controller.
Parameters
|
Parameter Name |
Data Type |
Default Value |
Description |
|---|---|---|---|
|
bit_start |
int |
- |
Beginning contact number for input signals (1-20) |
|
bit_end |
int |
- |
Ending contact number for input signals (1-20) |
Note
-
Bit_end must be a larger number than bit_start.
-
17 - 20 are inputs of the SI1 - SI4 terminals.
