Overview of IEC 60870-5-104 and the Supervisor

IEC 60870-5-104 is a communication standard for telecontrol particularly for the power generation and distribution market. It is a master slave protocol operating over TCP/IP. In the case of the Supervisor, it is the master and the field devices are the slaves. Both polling and unsolicited data exchange are supported. In general, polling is only used at startup to collect the initial state of slaves. After that data is collected from a slave when it changes.

∙An IEC 60870-5-104 network has Devices, Sectors and Information Objects.

∙ A Device can either be a data concentrator, collecting together several discrete Sectors, or it can have integrated Sectors. Often a Device will only have one Sector making the Device and Sector synonymous. Each Device is identified on the

network by its TCP/IP address.

∙ A Sector is typically a piece of control equipment with one or more Information Objects - for example a circuit breaker.

∙Information Objects represent the physical inputs and outputs. The types of Information Object that are available is strictly controlled by the IEC 60870-5-104 specification. Each type has a corresponding ASDU (Application Service Data Unit) which defines the structure, type and format of messages.

IEC 60870-5-104 within the Supervisor

IEC 60870-5-104 support within the Supervisor is provided by the Triangle MicroWorks communication stack which is integrated into the Supervisor's Communication Manager. The Supervisor's IEC 60870-5-104 configuration is accessed from the Application Explorer - .Communication.Data acquisition.IEC 60870-5-104.
