Saving Settings to Non-volatile Memory
Any changes made from the RUI are always saved to
non-volatile memory (EEPROM) of the module it is
connected to. If a module loses power or is switched
off, its settings will be restored when power is reap-
plied.
The EEPROM has a limited life calculated to
be approximately 1,000,000 writes. Over the life of
any given RM module this limitation would not be a
problem when changes are made exclusively from the
RUI. However, if an RM module is receiving instruc-
tions from a PLC or a computer through a network
connection where the frequency of the write opera-
tions could be high, the EEPROM life could expire
much quicker.
By default, settings made through the network
are not saved to nonvolatile memory (59). However,
as stated above, changes made via the RUI are saved
to EEPROM, regardless of the setting of non-volatile
memory save. This parameter can be changed via the
communications network in use, through the RUI or
via EZ-ZONE Configurator software. This parameter
can be found in the User's Guide for each RM module
in the Setup Page under the Communications Menu.
Note:
This setting must be changed to the desired setting
for each module individually.
