9. SubIndex is the parameter sub-index number that is intended to write into the IO-Link device. The sub-index number
can be set from 0 to 255. If the value exceeds the setting range, the Error flag switches to ON.
10. DateType is the parameter data type of the IO-Link device. You need to set the correct datatype before executing this
instruction. Refer to API1426 IOLINKR instruction for more information.
11. DataWrite is the data written into the IO-Link device; unit: byte, arranged by high byte and low byte.
12. WriteLen is the data length of the data to be written into the IO-Link device; unit: byte.
13. Done is a communication complete flag. When this flag is ON, it indicates the parameters have written into the IO-
Link device completely.
14. Error is a communication error flag. When this flag is ON, it indicates an error occurs during the communication among
the PLC CPU, AS04SIL and the IO-Link device. Refer to the Error Codes from API1426 IOLINKR instruction for
troubleshooting.
18. The communication process among the PLC CPU, AS04SIL and IO-Link device:

19. Sequences of the EN, Done, and Error flags: when an error occurs during communication (scenario 1) and when the
communication is compete (scenario 1).
6-542
A: The PLC CPU sends data to AS04SIL.
B: AS04SIL sends data to the IO-Link device.
C: the IO-Lind Device is processing the request
and send data to AS04SIL.
D: The PLC CPU updates the status (DONE /
ERROR) and receives the data.
