Examples

NEXUS IC Examples

• Example 1: Get system version

  1. Import NEXUSIC_RESTAPI

     from pynexusic import NEXUSIC_RESTAPI as api
     

  2. Initialize NEXUSIC_REST class

     NX_REST = api.NEXUSIC_REST(baseURI, api_key=APIKey)
     

     where APIKey is the user's API Key provided by the system administrator

  3. Execute required function

     result, result_status_code = NX_REST.getVersion()
     

     Output:

     result = {'version': 'x.x.xxxxx.x', 'schema': 'x.xxx'}
     result_code = 200
     

• Example 2: Run reports and get python object response

  1. Import NEXUSIC_RESTAPI

     from pynexusic import NEXUSIC_RESTAPI as api
     

  2. Initialize NEXUSIC_REST class

     NX_REST = api.NEXUSIC_REST(baseURI, api_key=APIKey)
     

     where APIKey is the user's API Key provided by the system administrator

  3. Execute required report

     result, result_status_code = NX_REST.getDashboard(report_name)
     

     where report_name is the name of the report to be executed in NEXUS IC

     Output:

     result = {'name': 'xxxxxxxxxxx', 
               'elements': [{'type': 'section', 'data': {}}, 
                            {'type': 'paragraph', 'data': {'text': [{'value': 'xxxxxx'}]}}
                           ]
               }
     result_code = 200
     

     The values of the elements key will contain the data configured in the NEXUS IC report template

OSI PI Examples

• Example 1: Get full list of points in the database

  1. Import OSIPI_WebAPI

     from pynexusic import OSIPI_WebAPI as OSIPI
     

  2. Initialize OSIPI_WebAPI class

     OSIPI_obj = OSIPI.OSIPI_WebAPI(piwebapi_uri, username, password)
     

     an example for piwebapi_uri is https://[domain].com/piwebapi

  3. Execute required function

     result, result_status_code = OSIPI_obj.getPointsList(pageSize=20000)
     

     Output:

     result = [{'ServerName': 'xxxxxxxxxxx',
                 'Points': [{'WebId': 'xxxxxxxxxx', 
                             'Id': xxxxx,
                             ...}],
                 'ResponseStatus': 200
               }]
     result_status_code = None
     

• Example 2: Get stream summary data

  1. Import OSIPI_WebAPI

     from pynexusic import OSIPI_WebAPI as OSIPI
     

  2. Initialize OSIPI_WebAPI class

     OSIPI_obj = OSIPI.OSIPI_WebAPI(piwebapi_uri, username, password)
     

     an example for piwebapi_uri is https://[domain].com/piwebapi

  3. Execute required function

     result, result_status_code = OSIPI_obj.getStreamDataSummary(webID, startTime='*-2mo', endTime='*-1mo', summaryType='Average')
     

     where webID is the required stream webID, for more details see OSI PI documentation

     Output:

     result = {'Links': {},
                 'Items': [{'Type': 'Average', 
                             'Value': {'Timestamp': 'xxxxxxxx',
                                         'Value': xxxxxx,
                                         ...}
                             }]
               }
     result_status_code = 200
