Byte Order
Register Address The Modbus register address inside the slave device for the point.
Bit inside the Bit inside the Modbus register (optional). The gateway allows bit decoding from
register generic 16 bits input/holding Modbus registers.
Bit coding into 16 bits input/holding Modbus registers is used for some devices to
encode digital values into this type of registers, being these registers normally
accessible using Modbus function codes 3 and 4 (read holding/input registers).
