AL1921 IO-Link master with EtherNet/IP interface
48
Device validation and backup / restore of parameter values are only available if the “IO-Link”
operating mode of the port has been activated.
For options [Type compatible V1.1 device with Backup + Restore] and [Type compatible V1.1
device with Restore]: If the parameters [Vendor ID] or [Device ID] are changed in online mode,
the data memory is deleted and the parameter values of the connected IO-Link device are
backed-up again in the IO-Link master.
Substructure: iolinkmaster/port[x] (x: 1…8)
Available data points:
Name Description Value range Access

age_mode
Behaviour of the port when connecting a
new IO-Link device
• 0: No check and clear
• 1: Type compatible V1.0 device
• 2: Type compatible V1.1 device
• 3: Type compatible V1.1 device
with Backup + Restore
• 4: Type compatible V1.1 device
with Restore

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
