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]
Here we find the solutions Ethernet/IP, three versions of PROFINET IO - the classes A, B, and C - and the solutions of P-NET, [28] Vnet/IP [29] TCnet, [30] EtherCAT, Ethernet POWERLINK, Ethernet for Plant Automation (EPA), and also the MODBUS with a new Real-Time Publish-Subscribe MODBUS-RTPS and the legacy profile MODBUS-TCP.
The connector between the vehicles is the 18-pole UIC connector. Since connectors are exposed and can oxidize, a current pulse is applied at connection establishment to evaporate the oxide layer, called fritting. The standard connector for the WTB nodes is a DIN 9 pin connector. The physical level uses RS-485 levels at 1 Mbit/s data rate.
System Configuration description Language formerly known as Substation Configuration description Language (SCL) is the language and representation format specified by IEC 61850 for the configuration of electrical substation devices. This includes representation of modeled data and communication services specified by IEC 61850–7–X standard ...
Modbus TCP nomenclature is the same as for the Modbus over Serial line protocol, as any device which send out a Modbus command, is the 'client' and the response comes from a 'server'. [29] The ADU for Modbus TCP is officially called Modbus TCP/IP ADU by the Modbus organization [30] and is also called Modbus TCP frame by other parties. [3]

M12 connectors are mechanically "A"-coded according to IEC 61076-2-101. [5] Female connectors are assigned to the master and male connectors to the device. At the master pin 1 to pin 3 provides 24V DC power with max. 200 mA for an optional power supply of the IO-Link device. Pin 4 is used as a digital input (DI) or digital output (DO) according ...
Industrial environments are often much harsher, often subject to oil sprays, water sprays, and physical vibrations, so often industrial Ethernet requires a more rugged and watertight connector on one or both ends of the Cat 5 or Cat 6 cable, such as M12 connectors or M8 connectors, rather than the 8P8C connectors commonly used in homes and ...
