18.8.1 Introduction
M11910-3 v3
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.

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 IA is connected. IB, IC, VA, VB, VC, P, Q, F are optional but there
can be no holes.
• 3.4 Will be generated if IN and VN are present.
• 3.3 Will be generated if IB, VAB, P and Q present.
• 3.2 Will be generated if IB, VAB, and P or Q missing.
• 3.1 Will be generated if IB is present and IA is missing (otherwise I_B in 9).
Description for I103MEAS function block:
9 = IA
3.4 = IN AND VN
3.3 = IB AND VAB AND P AND Q
3.2 = IB AND VAB AND NOT 3.3
3.1 = IB AND NOT (3.2 OR 3.3 OR 9)
