Third / Fifth Words - 2, 3, 4: Parameter Number and Value
The third and fourth words in the output table, Parameter Value, are used by the
WRITEPARAM command. The fifth word is the parameter ID, used by the
WRITEPARAM and READPARAM commands. Parameter values are written with the
least significant word first and one 32-bit integer per parameter. For details see the
Parameter Table below. Expanded descriptions are listed below the table by hex number.
All parameters are DINT.
There are 14 spare parameters for possible future use.
Notes
When set by a command, all parameters except the rate setpoint are saved to non-volatile
memory. Both rate and scale calibrations are saved automatically when completed
successfully. Totals are not saved automatically when changed, and will be lost if no
WRITENONVOLATILE command is executed before power down.
The section above “Format Word Decimal Point Parameters” explains Weight DP, Rate
DP, and Total DP, which appear in the chart below.
