18.6 IEC 60870-5-103 communication protocol
18.6.1 Introduction
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.
18.6.2 Measurands for IEC 60870-5-103 I103MEAS
18.6.2.1 Functionality
103MEAS is a function block that reports all valid measuring types depending on
connected signals.
The set of connected input will control which ASDUs (Application Service Data
Units) are generated.
• 9 Will be generated if at least IL1 is connected. IL2, IL3, UL1, UL2, UL3, P, Q,
F are optional but there can be no holes.
• 3.4 Will be generated if IN and UN are present.
• 3.3 Will be generated if IL2, Ul1L2, P and Q present.
• 3.2 Will be generated if IL2, UL1L2 and P or Q missing.
• 3.1 Will be generated if IL2 present and IL1 missing (otherwise IL2 in 9).
Description for I103MEAS function block:
9 = IL1
3.4 = IN AND UN
3.3 = IL2 AND UL1L2 AND P AND Q
3.2 = IL2 AND UL1L2 AND NOT 3.3
3.1 = IL2 AND NOT (3.2 OR 3.3 OR 9)
