Applicable services:
Name Description

9.2.12.1 Example: Cloning the data memory of an IO-Link port
Task: The data memory of port 2 of IO-Link master 1 is to be cloned to IO-Link master 2.
Solution: The cloning consists of 2 steps. In the first step, the data memory of the port is read by IO-
Link master 1. In the second step, the read data is stored in the data memory of the port of IO-Link
master 2.
Read data memory
u Read segment size of the data storage (h = number of bytes)
{
"code":"request",
"cid": -1,
"adr":"/iolinkmaster/port[2]/datastorage/chunksize/getdata"
}
Example: h = 256
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").
