The AS-i/Modbus gateway can transmit up to 15 registers in one telegram.
Addresses with index correspond with the bits or bytes within one register: “Address
Bit” corresponds to the value 2 bit and “Address Byte” corresponds to the lower-/upper
half of the accessed register.
The bits 0, 4, 8 and 12 are connected with the data connection D0 of the AS-i slaves,
bits 1, 5, 9 and 13 with D1,
bits 2, 6, 10 and 14 with D2,
bits 3, 7, 11 and 15 with D3.
