Record download
It's possible to download Sentinel record by MODBUS interface.
There is no specific function to download file. The function 0x03 used in the preceeding paragraphs to read data is used in this procedure too.
Reading procedure is the following:
- Read Block 10 in order to position at the beginning of the recorded data and download the first 8 record.
- Read Block 11 to move forward on next 8 records and read them.
- Repeat the previous step until there are records to download.
Whenever reading procedure of Block 11 will fail and it is required to repeat it in order to avoid to move forward by 8 records loosing data
contained in the previous reading is to be used Block 12 which allow to read the 8 current records without moving forward in the records list.
Referring to these latest three blocks (10,11 and 12), the acquisition will require always the complete lenght of 144 bytes (8 records). In case
a minor amount of data would be present the reply will contain the available ones and the third byte of the reply, containing the byte number of
the data, will be consequently set. Sequential reading, exceedind end of data will return always zero lenght.
