	)

Callback function to write user record data requested by the IO controller.

This function first checks if the asynchronous record write mode is activated. If not, it writes the record data from the buffer provided by Profinet stack to the corresponding array element. Otherwise, it sends a notification to the stack informing it that the write response will follow later.

Parameters

[in]	pnHandle	Profinet API Handle.
[in]	api	Application Process Identifier.
[in]	arNum	AR number.
[in]	sessionKey	AR session key.
[in]	sequenceNum	Sequence number.
[in]	addr	Geographical address (slot/subslot) of the module/submodule.
[in]	recordIndex	Index of the record.
[in]	bufLen	Length of data to write.
[in]	buffer	Buffer containing data to be written.
[in,out]	errState	Profinet status.

Returns

result of the operation as uint32_t.

Return values

PN_API_OK	Success.
PN_API_NOT_OK	Something went wrong.
PN_API_ERR_PARAM	Invalid parameter.
