6.1.8 IEC 101/104
The standards IEC 60870-5-101 and IEC 60870-5-104 are closely related. Both are derived from the
IEC 60870-5 standard. On the physical layer the IEC 101 protocol uses serial communication whereas
the IEC 104 protocol uses Ethernet communication. The IEC 101/104 implementation works as a slave
in the unbalanced mode.
For detailed information please refer to the IEC 101/104 interoperability document ( www.arcteq.fi/
