How does IEC 104 protocol work?
IEC 104 enables communication between control station and a substation via a standard TCP/IP network. The communication is based on the client-server model. As other monitoring protocols, IEC 104 transmits ASDU containing information objects and information elements which build the basic part of IEC 104 monitoring.
What is IEC 101 protocol?
IEC 60870-5-101 is a standard for power system monitoring, control & associated com- munications for telecontrol, teleprotection, and associated telecommunications for electric power systems.
What is IEC 608705 101 104 standard?
IEC 60870-5-104 (also known as IEC 870-5-104) is an international standard, released in 2000 by the IEC (International Electrotechnical Commission). IEC 60870-5-104 enables communication between control station and substation via a standard TCP/IP network.
What is ASDU address?
The optional second byte of the Cause of Transmission field is the Originator Address. It is the address of the originating controlling station so that responses can be routed back to it. Common Address of ASDU (1 or 2 bytes) – the address of the target station or the broadcast address.
What is the difference between 101 and 104 protocol?
The differences are mainly in the representation of timestamp information. While IEC-101 uses timestamp of type CP24Time2a, that can represent timing information from one hour down to a millisec- ond, IEC-104 uses CP56Time2a which extends the one hour to 100 years with the same granu- larity of one millisecond.
What is the difference between IEC 101 and IEC 104?
What is asdu in IEC 60870?
ASDU – Application Service Data Unit. Data structure that holds application layer information to exchange between a control centre and a remote terminal unit. IEC 60870-5-101/104 – Protocol serial or TCP/IP to exchange data from a substation to the control centre.

Which is the IEC standard for serial data transmission?
IEC 60870-5-104 Protocol (aka IEC 104) is a standard for telecontrol equipment and systems with coded bit serial data transmission in TCP/IP based networks for monitoring and controlling geographically widespread processes.

What is the use of IEC 60870-5-101?
The protocol has found widespread use in the energy sector, and is still used today. It is based on the EPA architecture (Enhanced Performance Architecture) and defines only the physical link and application layers of the OSI model. IEC 60870-5-101 is primarily used with relatively slow transmission media on the asynchronous V.24 interface.
