Note
The address type is the combination of the address type name in
UDM (Page 9) and data
type. For example, IB means bit in memory I.
The values should f
ollow the rule: Local address + Data length ≤ Max value of Local address
type.
5.4.6.5 RESTful API
CIM also provides a REST interface for those users that are familiar with such technology and
want to interact with CIM using an automated or programmed interface.
If the device connected to CIM supports RESTful, you can get or put data on UDM through
RESTful API. For example, you can access the UDM interface by a Swagger user interface,
which contains a detailed description of the classes, methods and parameters.
