Standards
IEC 60870-5 series – Details (I)

IEC 60870-5-101
This standard defines the functionality for the interoperability of telecontrol
equipment of different manufactures for the communication between substations
(outstations) and between substation (outstation) and control centers (central
station). Therefore it applies to telecontrol equipment and systems with coded bit
serial data transmission for controlling and monitoring geographically
widespread processes.

IEC 60870-5-102
It standardizes the transmission of integrated totals representing the amount of
electrical energy transferred between power utilities, or between a power utility
and independent power producers on a HV or MV network as a part of energy
management systems functionality. It is not concerned with LV networks or the
interfaces to the energy consumption meters themselves. In general the values
of integrated totals are transmitted at periodic intervals to update the energy
interchanges.

Standards
IEC 60870-5 series – Details (II)

IEC 60870-5-103
This standard is used to upload protection data. It is applicable for substation
automation systems with star coupled protection devices using point-to-point
links and a master slave transmission procedure.

IEC 60870-5-104
This standard enables Application Data Units, as defined in IEC 60870-5-101, to
be transmitted over a variety of digital data networks using the standard TCP-IP
transport interface. Thus the specifications of this standard present a
combination of the application layer of IEC 60870-5-101 and the transport
functions provided by a TCP/IP. Within TCP/IP various network types can be
utilised including X.25, FR (Frame Relay), ATM (Asynchronous Transfer Mode),
and ISDN (Integrated Service Data Network).
