______
1)
function is integrated in the Master Module
2)
not limited (limited only by free memory)
3)
due to performance matters (initialization times upon connection setup), no more than 2000 data
points are recommended
4)
max. startup time (with 10000 data points): approx. 4 min
min. startup time (with 1 data point): approx. 30…60 s (dependent on the configuration of the AU)
5)
supported with restrictions (for details see SICAM RTUs • Ax 1703 Common Functions Protocol
Elements, chapter “LAN Communication (61850)”, section Basic Data Types” and “Conversion
IEC 60870-5-101/104 ↔ IEC 61850“)
