*Registers marked with an asterisk (*) cannot be written to unless a specific procedure is followed. Contact
Apogee Instruments to receive the procedure for writing these registers.
Write only registers (function code 0x10).
Integer Registers
Packet Framing:
Apogee sensors use Modbus RTU packets and tend to adhere to the following pattern:
Slave Address (1 byte), Function Code (1 byte), Starting Address (2 bytes), Number of Registers (2 bytes), Data
Length (1 byte, optional) Data (n bytes, optional)
Modbus RTU packets use the zero-based address when addressing registers.
For information on Modbus RTU framing, see the official documentation at
http://www.modbus.org/docs/Modbus_Application_Protocol_V1_1b3.pdf
