PN_ISO_initGPIOEvent()

PNISOM_Handle PN_ISO_initGPIOEvent	(	PN_Handle	pnHandle,
		uint8_t	isoMode,
		uint32_t	timeval,
		uint32_t	duration
	)

API to initialize the ISOM event/signal. Returns the ISOM handle. The Event/signal will be disabled by default.

Parameters

	pnHandle	Profinet Handle
[in]	isoMode	ISOM type - PNISO_MODE_GPIO/PNISO_MODE_INTERRUPT
[in]	timeval	time in nanosecond to trigger the event/signal (Reference is Start of Cycle)
[in]	duration	Duration of signal in nanoseconds

Return values

ISOM	handle on success

PN_ISO_enableGPIOEvent()

void PN_ISO_enableGPIOEvent	(	PN_Handle	pnHandle,
		PNISOM_Handle	isoHandle
	)

API to enable the ISOM event/signal generation.

Parameters

pnHandle	Profinet Handle
isoHandle	ISOM handle that needs to be enabled

PN_ISO_disableGPIOEvent()

void PN_ISO_disableGPIOEvent	(	PN_Handle	pnHandle,
		PNISOM_Handle	isoHandle
	)

API to disable the ISOM event/signal generation.

Parameters

pnHandle	Profinet Handle
isoHandle	ISOM handle that needs to be disabled

PN_ISO_deInitGPIOEvent()
