Modbus register maps
A.7 Sample mode parameters
The sample mode parameters register (Table 23) defines basic counting characteristics
of a sample. Any updates to these registers will restart any active sample sequences.
A.8 Diagnostic data
Table 24 shows the Diagnostics data register that is updated at a 30 second (default) rate
or at the conclusion of any Test mode diagnostics.
