Modbus register maps
A.3 Data label
Table 18 provides a register for sample and analog data labels.
A.4 Sample data
Sample data records ( Table 19 ) are updated at each polled interval regardless of the
sample and hold times in the configuration registers. If real-time data is not required, use
the buffered records (address 500+).
