The 1-bit state reading feature (Coil, Input Coil) is still incomplete in the "Device" node of the library #7
Description
Hi, after some time of experimenting, I found that the feature with 1-bit status is not suitable. The problem here is that the current bpRegisters definition of this library focuses on reading the registers and not on reading 1-bit data points.
Suppose when I select FC1 or FC2 in the code field, the fields such as: Multiplier, Size, Format, Unit name and Unit scale must be suitable for 1 bit format. Specifically as follows:
1: When selecting FC1 or FC2, the fields Multiplier, Unit name and Unit scale must be omitted or empty (because FC1 and FC2 return bool data).
2: When selecting FC1 or FC2, the bool data type must be added in the "Format" field. Suppose I want to read addresses 1, 7, 12, 25 with the current formats, I see that the output is not suitable. YOU SHOULD CONSIDER THIS SUGGESTION OF MYS.
3: When selecting FC1 or FC2, the size field must be removed. Because it is in bit format, not byte format. You cannot only read 1 or 2 data points and declare the whole size = 1 equivalent to register, that is quite redundant. Not to mention there are cases where the user needs to read non-consecutive bits.
Finally, the scenario I want to talk about is that instead of reading registers FC3 and FC4, I now read non-contiguous addresses in FC1 or FC2, then the output result must also return the result as a bool array with the corresponding bits after reading the non-contiguous addresses at the input
