What is IEC 104 protocol?
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 difference between a 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 101 protocol?
The HTTP 101 Switching Protocols response code indicates a protocol to which the server switches. The protocol is specified in the Upgrade request header received from a client. The server includes in this response an Upgrade response header to indicate the protocol it switched to.
What is DNP3 protocol specification?
DNP3, also known as IEEE Std 1815, is a comprehensive protocol standard that defines the rules by which computers communicate with one another. Initiated in 1993, the DNP3 protocol specifically defined the interaction between utility computer systems with remote communication in mind.
What does IEC mean?
the International Electrotechnical Commission
IEC stands for the International Electrotechnical Commission: An “organization that prepares and publishes international standards for all electrical, electronic and related technologies.”
Where is DNP3 used?
Distributed Network Protocol 3 (DNP3) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies.
What is the difference between Modbus and DNP3?
Modbus is an application layer protocol whereas DNP3 consists of Application and Data Link Layers. Both protocols are used over many different types of transport, such as RS-232, RS-485, and TCP/IP. When it comes to TCP/IP, Modbus has a separate variant called Modbus TCP/IP but the DNP3 is wrapped within TCP/IP.

Is DNP3 an Ethernet?
DNP3 comes in Ethernet and Serial versions. Chipkin knows this protocol to source code level – get expert support (Level 1,2) and configuration from day 1. We carry a wide selection of DNP3 gateways that can connect to over 150+ protocols.
Is DNP3 serial?
Initially DNP3 used serial communications as IEC 60870-5-101, nowadays DNP3 allow using TCP/IP or UDP/IP communications over IP networks to improve the system communication response time. DNP3 is a protocol based on numerical identification of the data objects.
