The standard supports some specific protection functions and provides the vendor a facility to incorporate its own protective functions on private data ranges. It defines a companion standard that enables interoperability between protection equipment and devices of a control system in a substation. Unfortunately due to the increase in complexity vendors are 870–2 to roll this out on their networks. The control field data of IEC contains various types of ief for effective handling of network data synchronization.

Part 5 provides a communication profile for sending basic telecontrol messages between 870–52 systems, which uses permanent directly connected data circuits between the systems. The IEC Technical Committee 57 Working Group 03 have developed a protocol standard for telecontrol, teleprotection, and associated telecommunications for electric power systems.
