The device complying with this standard can send the information using two methods for data transfer – either using the explicitly specified application service data units ASDU or using generic services for transmission of all the possible information. Unfortunately due to the increase in complexity vendors are reluctant to roll this out on their networks.

The IEC Technical Committee 57 Working Group 03 have developed a protocol standard for telecontrol, teleprotection, and associated telecommunications for electric power systems.

It defines a companion standard that enables interoperability between protection equipment and devices of a control system in a substation. The control field data of IEC contains various types of mechanisms for effective handling of network data synchronization. IEC standard has six parts, defining general information related to the standard, operating conditions, electrical interfaces, performance requirements, and data transmission protocols.

Five documents specify the base IEC The standard supports some specific protection functions and provides the vendor a facility to incorporate its own protective functions on private data ranges. Part 5 provides a communication profile for sending basic telecontrol messages between two systems, which uses permanent directly connected data circuits between the systems.
