Note: Some values will be rounded off to fit in the four-character display. Full values can be read with Modbus.
* Low register numbers contain the two higher bytes; high register numbers contain the two lower bytes of the four-byte integer.
Decimal precision is implied at three decimal places unless otherwise noted.
** Timer model only (SD31-XXXX-XTXX)
Caution: Writing to registers continuously, such as ramping set points via comms, will damage the SD31 EEPROM memory. See page 59.
