What is BS EN 60870-6-503 - Telecontrol equipment and systems about?
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.
