PN_APP_IOD_cbDataRead()

PN_API_IOD_IOXS PN_APP_IOD_cbDataRead	(	PN_API_IOD_Handle_t *const	pnHandle,
		PN_API_IOD_DevAddr_t *const	addr,
		const uint32_t	bufLen,
		uint8_t *const	buffer,
		const PN_API_IOD_IOXS	remoteIops
	)

Callback function to read output data from the IO controller to the physical output of a submodule. If output data is invalid, replacement substitute value is used.

This function reads data from the buffer provided by the stack to the global output data array if data is valid, else replacement substitute value is copied and used instead. It also turns ON/OFF some LEDs based on the value received. IOPS of the corresponding submodule is also updated while IOCS is sent back as a return value.

Parameters

[in]	pnHandle	Profinet API Handle.
[in]	addr	Geographical address (slot/subslot) of the submodule.
[in]	bufLen	Length of data.
[in]	buffer	Pointer to data buffer to read from.
[in]	remoteIops	IOPS from the IO controller, can be: PN_API_IOD_STATUS_BAD or PN_API_IOD_STATUS_GOOD.

Returns

Local IOCS as PN_API_IOD_IOXS.

Return values

PN_API_IOD_STATUS_GOOD	Data received is good.
PN_API_IOD_STATUS_BAD	Data received is bad.
