handle returned by previous call to OCXcip_Open

idobject

Pointer to structure of type OCXCIPIDOBJ

Description

OCXcip_GetIdObject retrieves the identity object for the module.

apihandle must be a valid handle returned from OCXcip_Open.

idobject is a pointer to a structure of type OCXCIPIDOBJ. The members of this

{

WORD VendorID; //Vendor ID Number

WORD DeviceType; //General product type

WORD ProductCode: //Vendor-specific product identifier

BYTE MajorRevision; //Major revision level

BYTE MinorRevision; //Minor revision level

DWORD SerialNo; //Module serial number

BYTE Name [32]; //Text module name (null-terminated)

} OCXCIPIDOBJ;

Return Value

OCX_SUCCESS

ID object was retrieved successfully

OCX_ERR_NOACCESS

apihandle does not have access

Example

OCXCIPHANDLE apihandle;

OCXCIPIDOBJ idobject;

// Read ID data from ControlLogix in slot 0

OCXcip_GetIdObject(apihandle,&idobject);

printf ("ModuleName: %s Serial Number: %lu\n",

idobject.Name, idobject.SerialNo);
