w The data storage mechanism on IO-Link device will be activated.
w The IO-Link device synchronises changed parameter values with data storage of the IO-Link
master.
9.2.17.1 Example: Reading a parameter value of an IO-Link device
Task: Reading the serial number of the ifm temperature sensor TN2531 at port 2.
Solution: Read the serial number with the iolreadacyclic service from the IO-Link device (index:
21, subindex: 0)
Request:
{
"code":"request",
"cid":4711,
"adr":"/iolinkmaster/port[2]/iolinkdevice/iolreadacyclic",
"data":{
"index":21,
"subindex":0
}
}
Response:
{
"cid":4711,
"data":{"value":"4730323134323830373130"},
"code":200
}
The returned value is displayed in hexadecimal format. Converting the HEX value to a STRING value
results in: G0214280710.
9.2.17.2 Example: Writing a parameter value of an IO-Link device
Task: Setting the output configuration OUT1 of the ifm temperature sensor TN2531 at port 2 to the
value "Hnc / hysteresis function, normally closed".
Solution: Set the parameter [ou1] of the sensor with the service iolwriteacyclic to the value 4.
The parameter can be accessed via IO-Link Index 580, Subindex 0 (Ò IO-Link description of the
sensor).
Request:
{
"code":"request",
"cid":4711,
"adr":"/iolinkmaster/port[2]/iolinkdevice/iolwriteacyclic",
"data":{
"index":580,
"subindex":0,
"value":"34"
}
}
The value must be passed in hexadecimal format. Converting the STRING value to a HEX value
results in: 34.
