It will take a few seconds for the relay to restart after the completion of the update process. Therefore, before unplugging
the relay, please make sure that the relay main screen shows the analog inputs values.
IMPORTANT NOTICE:
®
The MODBUS
memory map may change for different firmware versions. As a result, the Flash memory update, when
®
upgrading to a higher model (OPTION 1 or 2), may involve a MODBUS
memory map change. This may result a critical
issue when the relay is integrated in a system, and the user should take into account the modifications that will have to be
performed in the programs that access the MIFII relay memory maps.
Additionally, when a Flash memory update is performed, the loading program will enter the default settings. This
means that the user will need to adapt the settings to the real situation of the protected device. If the user wants to keep the
same settings after the memory update, a copy of the settings should be stored in a file before starting the update process.
