IEC part 5 [1] is one of the IEC set ief standards which define systems used for telecontrol supervisory control and data acquisition in electrical 6070-4 and power system automation applications. Part 5 provides a communication profile for sending basic telecontrol messages between two 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.

The result of this work is IEC Five documents specify the base IEC The standard is suitable for multiple configurations like point-to-point, star, mutidropped etc. The details of variable length frame is given below. It 608870-4 a companion standard that enables interoperability 60807-4 protection equipment and devices of a control system in a substation. 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.

The standard supports some specific protection functions and provides the vendor a facility to incorporate its own protective isc on private data ranges. IEC uses FT1.

However the frame format of IEC differs from IEC in information object address which is split into function type ftype and information number inumber in IEC Also IEC can have only single information object in a frame whereas IEC can have multiple information objects. Many of the field sizes are also restricted in IEC Application layer of IEC is preserved same as that of IEC with some of the data types and facilities not used.

The control field data of IEC contains various types of mechanisms for effective handling of network data synchronization. Though the IEC technical committee TC 57 have published a security standard IECwhich implements end-to-end encryption which would prevent such attacks as replay, man-in-the-middle and 608704- injection.
