The following tables show the mapping of the recorder parameters into Modbus registers. Knowledge of these
Modbus register assignments is only needed to make use of third party communications software. Both
registers
– high and low, must be accessed together to ensure valid data. The data is Modbus default byte
order and the registers DO NOT use zero byte addressing. Data encoding is first word low (32 bit data).
