Input Register
Siemens controllers use 2 predefined address areas. Therefore, the
input and output registers can each be accessed via 2 addresses,
one KUNBUS address and one Siemens address. Both addresses
address the same memory cell, however. No separate address areas
is defined for the input register. Read the holding register with
function code 0x04.
Register area for bit by bit access (coils)
You can also access the input and output data area bit by bit via
coils. The same memory is addressed with the coils as with the
registers.
Example:
Coils 1-16 correspond to the bits in register 1,
Coils 17-32 correspond to the bits in register 2.
