u Read total size of the data storage (g = number of bytes)
{
"code":"request",
"cid":-1,
"adr": "/iolinkmaster/port[2]/datastorage/size/getdata"
}
Example: g = 550
u Calculate the number of reading steps n: n = first integer value for which applies: g < n*h
Example: n= 3, da 550 < 3*256
u Read the data storage segment by segment ("pos" indicates the byte offset at which the read
process starts with the length "length").
{
"code":"request",
"cid":-1,
"adr":"/iolinkmaster/port[2]/datastorage/getblobdata",
"data":{"pos":0,"length":h}
}
{
"code":"request",
"cid":-1,
"adr":"/iolinkmaster/port[2]/datastorage/getblobdata",
"data":{"pos":h,"length":h}
}
{
"code":"request",
"cid":-1,
"adr":"/iolinkmaster/port[2]/datastorage/getblobdata",
"data":{"pos":2*h,"length":h}
}
...
{
"code":"request",
"cid":-1,
"adr":"/iolinkmaster/port[2]/datastorage/getblobdata",
"data":{"pos":n*h,"length":h}
}
Example:
1st read command: pos = 0, length = 256
2nd read command: pos = 256, length =256
3rd read command: pos = 512, length = 256
Each segment is returned as a BASE64-encoded string.
u Connect segments (concatenate).
Restore data memory
u Determine the size of the backed-up data storage content (n = number of bytes).
Example: n = 550
u Read segment size (s = number of bytes)
