EI_API_CIP_addInstanceService()

uint32_t EI_API_CIP_addInstanceService	(	T *	pCipNode_p,
		uint16_t	classId_p,
		uint16_t	instanceId_p,
		EI_API_CIP_SService_t *	pService_p
	)

Add one or more service/s to the class instance.

This function adds one or more service/s to the class with the class and instance identifiers passed as parameters classId_p and instanceId_p.

Remarks

The service EI_API_CIP_eSC_SETATTRSINGLE includes EI_API_CIP_eSC_GETATTRSINGLE, so its not necessary for a bitwise operation (or) for example (EI_API_CIP_eSC_GETATTRSINGLE | EI_API_CIP_eSC_SETATTRSINGLE).

Parameters

[in]	pCipNode_p	Pointer to the CIP node.
[in]	classId_p	Class identifier.
[in]	instanceId_p	Instance identifier.
[in]	pService_p	Service or services the class will support.

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_CLASS_BLACKLIST	Operation on the CIP object with specified identifier (class ID) are not allowed.
EI_API_CIP_eERR_CLASS_DOES_NOT_EXIST	Class does not exists in CIP node dictionary.
EI_API_CIP_eERR_INSTANCE_DOES_NOT_EXIST	Instance does not exist in CIP node dictionary.
EI_API_CIP_eERR_SERVICE_ALREADY_EXIST	Service already exist.
EI_API_CIP_eERR_SERVICE_PARAMETER	Wrong or invalid service parameters.
EI_API_CIP_eERR_SERVICE_INVALID	Service is invalid, possibly NULL pointer.
EI_API_CIP_eERR_MEMALLOC	Memory allocation error.
EI_API_CIP_eERR_NOT_IMPLEMENTED	Not implemented function.
EI_API_CIP_eERR_CLASS_UNKNOWN_STATE	Unknown state during class operation reached.

Example

 #include "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;
uint16_t classId = 0x0064;
 
// 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
errCode = EI_API_CIP_createClass(pEI_API_CIP_NODE, classId);
 
// Create instance in class with identifier classId
errCode = EI_API_CIP_createInstance(pEI_API_CIP_NODE, classId, 0x0001);
 
// Add services to instance 0x01 for the class with classId
// Example for Get_Attribute_Single
EI_API_CIP_SService_t srvc;
srvc.code = EI_API_CIP_eSC_GETATTRSINGLE;
errCode = EI_API_CIP_addInstanceService(pEI_API_CIP_NODE, classId, 0x0001, EI_API_CIP_eSC_GETATTRSINGLE)
 
// Example for Get_Attribute_All
EI_API_CIP_SService_t srvc_all;
 
// List of attribute ID's
uint16_t getAttributesAllResponseInstanceLevel01[] = { 1, 2, 3, 4, 5 };
srvc_all = { EI_API_CIP_eSC_GETATTRIBUTESALL, 5, getAttributesAllResponseInstanceLevel01 };
errCode = EI_API_CIP_addInstanceService(pEI_API_CIP_NODE, classId_p, 0x0001, &srvc_all);
