EI_API_CIP_createClass()

uint32_t EI_API_CIP_createClass	(	T *	pCipNode_p,
		uint16_t	classId_p
	)

Create a CIP class.

This function creates a CIP class. The class identifier is specified in parameter classId.

Parameters

[in]	pCipNode_p	Pointer to the CIP node.
[in]	classId_p	Class identifier.

Returns

EI_API_CIP_EError_t as uint32_t value.

Return values

EI_API_CIP_eERR_OK	Success.
EI_API_CIP_eERR_NODE_INVALID	CIP node is invalid, possibly EI_API_CIP_NODE_new() was not called.
EI_API_CIP_eERR_DICTIONARY_FULL	CIP dictionary is full, no more class or instance can be added.
EI_API_CIP_eERR_CLASS_ALREADY_EXIST	Class already exists in CIP node dictionary.
EI_API_CIP_eERR_MEMALLOC	Memory allocation error.
EI_API_CIP_eERR_INSTANCE_UNKNOWN_STATE	Unknown state during class operation reached.

Example

#include <api/EI_API.h>
 
 
EI_API_ADP_T* pEI_API_ADP = NULL;
EI_API_CIP_NODE_T* pEI_API_CIP_NODE = NULL;
uint32_t errCode;
 
uint8_t numInterfaces = 1;
 
// Create a new adapter first
pEI_API_ADP = EI_API_ADP_new(numInterfaces);
 
// Create a CIP node next
pEI_API_CIP_NODE = EI_API_CIP_NODE_new();
 
// Create a class with Class Code: 0x26 (Block Sequencer Object)
errCode = EI_API_CIP_createClass(pEI_API_CIP_NODE, 0x0026);
