This instruction is available for PLC with FW V1.08.50 or later and ISPSoft V3.12 or later.

You can refer to the IODD file of the IO-Link device to learn more about the device parameters. You can also use this

instruction to write the parameters into the IO-Link device.

There is no limit on the number of times you execute the instruction but only one instruction (IOLINKR or IOLINKW)

can be executed at a time.

During communication, it takes at least 5 seconds for the IO-Link device to response. Do NOT stop or start another

instruction during this time. After the communication with IO-Link is done, it is suggested to use the flags DONE or

ERROR to stop or start the instruction.

Group: The group number of AS04SIL that is connected to the right side of PLC directly or connected to the remote

module that acts as PLC, e.g. the first connected module is module number 1, the second connected module is number

2. Up to 15 modules can be connected. If the connected module is not AS04SIL, the Error flag switches to ON.

Module: The module number that is connected to the right side of PLC directly or connected to the remote module

that acts as PLC, e.g. the first connected module is module number 1, the second connected module is module number

2. Up to 32 modules can be connected and counted and each type of modules should be included in the count. If the

module is not AS04SIL, the Error flag switches to ON.

Port: The communication port number, ranging from 1 to 4. If the port number used is not the port for AS04SIL, the

Error flag switches to ON.

Index is the parameter index number that is intended to write into the IO-Link device.
