See Loading Setpoints from a File on page 4–21 for details.Modbus addresses assigned to firmware modules, features, settings, andcorresponding data items (i.e. default values, min/max values, data type, and itemsize) may change slightly from version to version of firmware.The addresses are rearranged when new features are added or existing features areenhanced or modified. The EEPROM DATA ERROR message displayed afterupgrading/downgrading the firmware is a resettable, self-test message intended toinform users that the Modbus addresses have changed with the upgraded firmware.This message does not signal any problems when appearing after firmwareupgrades.NOTE
