This module allows parameters to be saved in a non volatile memory. In order
to avoid storing configuration data parameters (registers 801...1000) by mista-
ke, storage is only executed when a specific signature is written to the appro-
priate register. The signature is “ST”.
Similarly, the default values of parameters are restored. On receipt of the correct
signature in the appropriate register, the device restores the default parameters.
The signature is “RS”.
The new configuration becomes active after a reset, i.e. after a “Power Down”
or a reset command (signature “RT”). See Register 400.
es.
Node address change by serial communications:
1.
Write the new address in register 801 (NodeA). - Write value.
2.
Write 0x5354 (ASCII code “ST”) to register 400. - Store value.
3.
Write 0x5254 (ASCII code “RT”) to register 400. - Cold reset.
The retentive device management data (registers 401... 800) are immediately
valid after writing. To maintain the values after a power OFF/ON cyle, the
command Store (“ST”) must be executed.

The data written at retentive and configuration registers are stored in EEPROM (see “Address
Map organisation” paragraph for details). This type of memory has a limited number of writing
cycles. Also if this number is very high (about 100000 cycles), this limit can be easily reached
if the storing process is forced through a serial communications line. Please check that the
storing procedure of these registers is not performed automatically.
