EFFECT OF POLL RATE + SUBSCRIBED POINTS ON CPU LOAD
The poll rate set for the CLIF-CBUSLC and the chosen number of subscribed datapoints both make a demand on the CPU load.
The following recommendations are therefore applicable.

No. of I/O modules per

I/O modules since they do not count as
L

devices.)
As many 25 I/O modules (combination of Panel
Bus I/O modules and L
ON
W
ORKS
I/O modules)
are possible, but with some risk.

* This corresponds mainly to the no. of datapoints in trend if these datapoints do not update faster than once per minute. In the
case of physical C-Bus systems, the update rate of each datapoint can be influenced by the user (i.e., by changing the attribute
"trend hysteresis").
