Scope and objectThis part of IEC 60870 applies to telecontrol equipment and systems with coded bit serial data transmission for monitoring and controlling geographically widespread processes. It defines a telecontrol companion standard that enables interoperability among compatible telecontrol equipment. The defined telecontrol companion standard utilizes standards of the IEC 60870-5 series. The specifications of this part present a combination of the application layer of IEC 60870-5-101 and the transport functions provided by a TCP/IP (Transmission Control Protocol/Internet Protocol). Within TCP/IP@ various network types can be utilized@ including X.25@ FR (Frame Relay)@ ATM (Asynchronous Transfer Mode) and ISDN (Integrated Service Data Network). Using the same definitions@ alternative ASDUs (Application Service Data Unit) as specified in other IEC 60870-5 companion standards (for example@ IEC 60870-5-102) may be combined with TCP/IP@ but this is not described further in this part. NOTE?? Security mechanisms are outside the scope of this standard.
