This part of ISO/IEC 14543 establishes general principles for network and device management shared by all installation modes for network based control of HES Class 1 and independent of the installation mode used. The aim is to standardize the interaction between a management client and a management server which leads to the successful configuration of the devices. The management procedures thus specify the highest level communication requirements between a management client and a management server. These requirements specify a) the sequence of messages that shall be exchanged between a management client and a management server, b) the contents and interpretation of the transported data, c) the action to take based on this data (setting internal resources, state machines, physical actions, …), and d) the error and exception handling. The management procedures are based on the application layer services. Some management procedures are solely based on the use of one or a sequence of dedicated application layer services to achieve the required goal. For these, ISO/IEC 14543-3-1 and ISO/IEC 14543-3-2 provide sufficient information concerning the underlying mechanisms. Other management procedures additionally use the application layer services to access internal data in the management server to achieve the required goal. This data is defined as objects as specified in ISO/IEC 14543-3-3.
