DIO_DEVICE_CFG_callback()

bool DIO_DEVICE_CFG_callback	(	EI_API_CIP_NODE_T *	pCipNode,
		uint16_t	classId,
		uint16_t	instanceId,
		uint16_t	attrId,
		EI_API_CIP_ESc_t	serviceCode,
		int16_t	serviceFlag
	)

Configuration callback to synchronize discrete io device profile non-volatile values with actual stack attribute values. Sets the new non-volatile data, if necessary.

Called by DEVICE_PROFILE_INTF_cfgCallback function of device profile interface. Function needs to be registered by DEVICE_PROFILE_register call.

Remarks

If actual stack attribute values are same as discrete IO device profile non volatile values then there is no need to write them to the non volatile memory.

Parameters

[in]	pCipNode	Pointer to CIP object.
[in]	classId	Class identifier.
[in]	instanceId	Instance identifier.
[in]	attrId	Attribute identifier.
[in]	serviceCode	Service code.
[in]	serviceFlag	Service flag.

Returns

value as bool.

Return values

true	Non volatile discrete IO device profile configuration part was changed.
false	No change.

Example

#include "device_profiles/discrete_io_device/discrete_io_device_cfg.h"
 
uint32_t DEVICE_PROFILE_register (DEVICE_PROFILE_INTF_Interface_t* pIntf)
{
    uint32_t error = DEVICE_PROFILE_INTF_ERR_General;
 
    if (NULL == pIntf)
    {
        error = DEVICE_PROFILE_INTF_ERR_PtrInvalid;
        goto laError;
    }
 
    ...
 
    pIntf->cfg.callback = DIO_DEVICE_CFG_callback;
 
    ...
 
    error = DEVICE_PROFILE_INTF_ERR_OK;
 
laError:
    return error;
}
