PN_API_IOD_arDisconnCbf

typedef void(* PN_API_IOD_arDisconnCbf) (PN_API_IOD_Handle_t *const pnHandle, const uint16_t arNum, const uint16_t sessionKey, const PN_API_IOD_ArReason_t reasonCode)

Callback function prototype to notify the user application that an AR connection with the IO controller has been terminated.

A connection termination event takes place when an established connection is either alarmed or deliberately terminated by the IO controller or the IO device.

Parameters

[in]	pnHandle	Profinet API Handle.
[in]	arNum	AR number.
[in]	sessionKey	Session key.
[in]	reasonCode	Reason code (see PN_API_IOD_ArReason_t)

Example

#include "pn_api_iod_callbacks.h"
#include "pn_api_iod_communication.h"
#include "pn_api_iod_startup.h"
 
//Implement the callback function in the user application
void PN_APP_IOD_cbArDisconn(PN_API_IOD_Handle_t *const pnHandle,
uint32_t arNum, PN_API_IOD_ArReason_t reasonCode)
{...}
 
PN_API_IOD_Handle_t* pnHandle = NULL;
uint32_t status;
 
pnHandle = PN_API_IOD_new();
 
//Store callback functions implemented by the user application
PN_API_IOD_Callbacks_t callbacks = {
    .arDisconn = PN_APP_IOD_cbArDisconn,
    ...}
 
//Register callback function
status = PN_API_IOD_registerCallbacks(pnHandle, &callbacks);
