PN_API_IOD_reportNewIpAddrCbf

typedef void(* PN_API_IOD_reportNewIpAddrCbf) (PN_API_IOD_Handle_t *const pnHandle, const uint32_t ipAddr, const uint32_t subnetMask, const uint32_t defaultGw)

Callback function prototype to inform the user about new IP address.

When the stack changes the IP address of the IO device, it calls this callback function which needs to be implemented by the user application to notify the user about this update. The implementation can be as simple as a printf.

Parameters

[in]	pnHandle	Profinet API Handle.
[in]	ipAddr	IP address.
[in]	subnetMask	Subnet mask.
[in]	defaultGw	Default gateway.

Example

#include "pn_api_iod_callbacks.h"
#include "pn_api_iod_settings.h"
#include "pn_api_iod_startup.h"
 
//Implement the callback function in the user application
void PN_APP_IOD_cbReportNewIpAddr(PN_API_IOD_Handle_t *const pnHandle,
const uint32_t ipAddr, const uint32_t subnetMask, const uint32_t defaultGw)
{...}
 
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 = {
    .reportNewIpAddr = PN_APP_IOD_cbReportipAddr,
    ...}
 
//Register callback function
status = PN_API_IOD_registerCallbacks(pnHandle, &callbacks);
