IEC60870-5-104
IEC 60870-5-104 (also known as IEC 870-5-104) is an international standard,
released in 2000 by the IEC (International Electrotechnical Commission). As can be
seen from the standard's full designation 'Network access for IEC 60870-5-101
using standard transport profiles', its application layer is based on IEC 60870-5-
101. IEC 60870-5-104 enables communication between control station and
substation via a standard TCP/IP network. The TCP protocol is used for connection-
oriented secure data transmission.
