Object 1010h: Store Parameters
This object supports the saving of parameters in non-volatile memory. In order to avoid storage of
parameters by mistake, storage is only executed when a specific signature is written to the
appropriate sub-index. The signature is “save”.
The signature is a 32-bit unsigned number, composed of the ASCII codes of the signature
characters, according to the following table:
MSB LSB
e v a s
65h 76h 61h 73h
On reception of the correct signature to an appropriate sub-index, the Thermocouple Scanner will
store the parameters in non-volatile memory, and then confirm the SDO transmission.
By read access, the object provides information about the module’s saving capabilities. For all sub-
indexes, this value is 1h, indicating that the Thermocouple Scanner saves parameters on
command.
This means that if power is removed before the Store object is written, changes
to the Object Dictionary will NOT have been saved in the non-volatile memory, and will be
lost on the next power cycle.
