   en.wikipedia.org/wiki/IEC_61850

   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]

3. DNP3 - Wikipedia

   en.wikipedia.org/wiki/DNP3

   It is primarily used for communications between a master station and RTUs or IEDs. ICCP, the Inter-Control Center Communications Protocol (a part of IEC 60870-6), is used for inter-master station communications. Competing standards include the older Modbus protocol and the newer IEC 61850 protocol. DNP overview diagram

4. Modbus - Wikipedia

   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]

   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.
