This corresponds to:
•
Number of events: 3 000 000
•
Number of logged values: 90 000 000
The maximum number of logged values corresponds roughly to 400 measurements
sampled every 15 minutes and stored for 1 + 5 years (current year + 5 years of history).
Process communication capacity7.3.
The capacity of one protocol means that only that protocol is used. If several protocols
are combined, the maximum capacity per protocol must be reduced proportionally.
Example: IEC 61850 and LON are combined in the system. The IEC 61850 IEDs represent
60% of the maximum IEC 61850 capacity. Then the actual maximum LON capacity is
40% of the indicated maximum capacity.
The following tables show the maximum communication capacity for the most commonly
used protocols.
