EC_API_SLV_CoE_getObjectData()

uint32_t EC_API_SLV_CoE_getObjectData	(	EC_API_SLV_SHandle_t *	pEcSlaveApi_p,
		EC_API_SLV_SCoE_Object_t *	pObject_p,
		uint32_t	length_p,
		uint16_t *	pData_p
	)

This function read the object data from the Object Dictionary.

Read object data from Object Dictionary. Data starts from subIndex 0.

Parameters

[in]	pEcSlaveApi_p	The pointer to the EtherCAT API instance.
[in]	pObject_p	Pointer to the object instance.
[in]	length_p	Data length.
[in]	pData_p	Pointer to the data.

Returns

uint32_t Returns the API error code.

Example

#include <ecSlvApi.h>
 
// required variables
EC_API_SLV_SCoE_Object_t* ptObject = NULL;
i32uErr_l = EC_API_SLV_CoE_getObject(ecSlaveApi, Index, &ptObject);
if (i32uErr_l == EC_API_eERR_NONE && ptObject != NULL)
{
    EC_API_SLV_CoE_getObjectData(ecSlaveApi, ptObject, length, pData);
    //do_some_stuff(pData);
}
