standard. It should also be noticed that these sets of data are mainly defined for a
single function protection IED. 630 series IEDs in turn are multifunctional
protection and control IEDs whose internal data model is based on the IEC 61850
standard.
Interoperability list
The standard requires the IEC 60870-5-103 device to provide an interoperability
list, which actually is more an interchangeability list. See the vendor specific
implementation section in this manual for the interoperability list.

substation automation system
IEC 60870-5-103 communication protocol is mainly used when a protection IED
communicates with a third party control or monitoring system. This system must
have software that can interpret the IEC 60870-5-103 communication messages.
