The device numbers are enumerated in ANSI/IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations. Many of these devices protect electrical systems and individual system components from damage when an unwanted event occurs such as an electrical fault .
WITS-DNP3 provides Secure Authentication between Master and Field Device and uses device vendor supplied Configuration Applications for limited plug and play functions. WITS-IoT is a JSON based application layer protocol designed for very large numbers of smaller devices which may be online only for brief periods.
IEC 60870 part 6 in electrical engineering and power system automation, is one of the IEC 60870 set of standards which define systems used for telecontrol (supervisory control and data acquisition) in electrical engineering and power system automation applications.
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations.It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems. [1]
IEC 60870 part 5, known as Transmission protocols, [1] provides a communication profile for sending basic telecontrol messages between two systems, which uses permanent directly connected data circuits between the systems.
IEC 61131-3 is the third part (of 10) of the international standard IEC 61131 for programmable logic controllers.It was first published in December 1993 [1] by the IEC; the current (third) edition was published in February 2013.
The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems.
