PN_API_IOD_arGetType()

PN_API_IOD_ArType_t PN_API_IOD_arGetType	(	PN_API_IOD_Handle_t *const	pnHandle,
		uint16_t	arNum
	)

Retrieves an application relation's type.

Application relation type can be "single", "supervisor", "single RTC3" or "single system redundancy".

Parameters

[in]	pnHandle	Profinet API Handle.
[in]	arNum	AR number.

Returns

AR type as PN_API_IOD_ArType_t.

Return values

PN_API_IOD_ArTypeSingle	Single AR.
PN_API_IOD_ArTypeSupervisor	Supervisor AR.
PN_API_IOD_ArTypeSingleRtc3	Single AR that uses RT_Class_3.
PN_API_IOD_ArTypeSingleSysRedundancy	System redundancy AR.

Example

#include "pn_api_iod_communication.h"
#include "pn_api_iod_startup.h"
 
PN_API_IOD_Handle_t* pnHandle = NULL;
uint32_t arNum = 1;
PN_API_IOD_ArType_t arType;
 
pnHandle = PN_API_IOD_new();
 
//Prepare and call PN_API_IOD_startup()
...
 
arType = PN_API_IOD_arGetType(pnHandle, arNum);
