Section 3 Configuration Data Subscription
3BSE037076-510 D 55
The lower subscription rate can be useful if the subscriber is only used to present an
overview of the providers state.
The configuration above specifies that properties with update rates 0-1 seconds will
get 10 seconds, 2-3 seconds will get 30 seconds and 4-9 second will get 60 seconds.
The delay is only affecting the cyclic data, i.e a faceplate will get data directly when
it is brought up.
These values must not overlap, i.e 0-10, 5-20 is not allowed, and only whole
seconds can be specified.
Figure 33. System Connection, Subscription Configuration
For Advant Master controllers the fixed cyclic rates (1s, 3s, or 9s) should be used
as subscription values freely selected may give a significant higher load in the
controller. See
System 800xA for Advant Master, Configuration (3BSE030340*)
for more guidelines regarding Advant Master data subscription.
