BS EN 60870 is a series on telecontrol equipment and systems. Telecontrol equipment and systems refer to the connection of process stations spread out over a wide area to central control systems. BS EN 60870-6-503 specifies a method of exchanging time-critical control centre data through wide-area and local-area networks using a full ISO compliant protocol stack. BS EN 60870-6-503 contains provisions for supporting both centralized and distributed architectures. BS EN 60870-6-503 includes the exchange of real-time data indications, control operations, time-series data, scheduling and accounting information, remote program control and event notification. Though the primary objective of TASE.2 is to provide control centre (telecontrol) data exchange, its use is not restricted to control centre data exchange. BS EN 60870-6-503 may be applied in any other domain having comparable requirements. Examples of such domains are power plants, factory automation, process control automation, and others. BS EN 60870-6-503 specifies the externally visible functionality of implementations together with conformance requirements for such functionalities.
Note: BS EN 60870-6-503 does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a computer system.
BS EN 60870-6-503 on telecontrol equipment and systems is useful for:
The Telecontrol Application Service Element (TASE.2) protocol (also known as Inter-Control Centre Communications Protocol, ICCP) allows for data exchange over Wide Area Networks (WANs) between a utility control centre and other control centres, other utilities, power pools, regional control centres, and Non-Utility Generators. Data exchange information consists of real-time and historical power system monitoring and control data, including measured values, scheduling data, energy accounting data, and operator messages. This data exchange occurs between one control centre's Supervisory Control And Data Acquisition/Energy Management System/Distribution Management System (SCADA/EMS/DMS) host and another centre's host, often through one or more intervening communications processors.
BS EN 60870-6-503 defines a mechanism for exchanging time-critical data between control centres. In addition, BS EN 60870-6-503 provides support for device control, general messaging and control of programs at a remote control centre. BS EN 60870-6-503 defines a standardized method of using the ISO 9506 Manufacturing Message Specification (MMS) services to implement the exchange of data. The definition of TASE.2 consists of three documents.
BS EN 60870-6-503 defines the TASE.2 application modelling and service definitions. IEC 60870-6-702 defines the application profile for use with TASE.2. IEC 60870-6-802 defines a set of standardized object definitions to be supported. TASE.2 describes real control centres with respect to their external visible data and behaviour using an object-oriented approach. The objects are abstract in nature and may be used in a wide variety of applications. The use of TASE.2 goes far beyond the application in the control centre to control centre communications.
BS EN 60870-6-503 must be understood as a toolbox for any application domain with comparable requirements. i.e., the TASE.2 may be applied in areas like substation automation, power plants, factory automation, chemical plants, or others that have comparable requirements. BS EN 60870-6-503 provides a generic solution for advanced Information and Communication Technology.
