3–26 350 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL
SOFTWARE SETUP CHAPTER 3: INTERFACES
After successfully updating the 350 firmware, the relay will not be in service and will
require setpoint programming. To communicate with the relay, the communication
settings may have to be manually reprogrammed.
When communications is established, the saved setpoints must be reloaded back into the
relay. See Loading Setpoints from a File for details.
Modbus addresses assigned to firmware modules, features, settings, and corresponding
data items (i.e. default values, min/max values, data type, and item size) may change
slightly from version to version of firmware.
The addresses are rearranged when new features are added or existing features are
enhanced or modified.
