C300 Controller performance data
The following table lists some C3000 Controller performance related data for quick
reference. Note that this information is subject to change without notice.
Performance Capacity
Block Performance 2400 Process Units (PUs) per second
with full cycle average CPU loading
(CPUCYCLEAVG) of no more than 60%.
Memory 16 MB user memory
Tagged Objects 4095 Total CMs, SCMs, UCMs, RCMs,
IOMs, and other named objects.
Alarms and Events 10 events per second.
Total I/O Budget 64 I/O units. Total for I/O types.
See Note 1 for example.
Number of I/O Links 2
Data Access Performance 2000 points per second.
Data Access Connections 12. Up to two servers and 10 console
Stations.
Peer to Peer Connections 30 Peer Connection Units.
Note 1: The C300 Controller supports up to a total of 64 I/O Units which can be
calculated in the following manner:
PMIO I/O Units + Series C I/O Units + Series A I/O Units + Fieldbus IO Units = 64
Where …
• One non-redundant or redundant PMIO IOM = 1 I/O Unit
• One non-redundant or redundant Series C = 1 I/O Unit
• The number of I/O Units assigned to any given Series A I/O device is specified for
that device.
• One non-redundant or redundant Series C Fieldbus Interface Module = 4 I/O Units
