The load in an Advant Controller 450 caused by a central operator station or information
management station subscription is a linear function of the number of “objects” (for example,
AI, DI, PIDCON) subscribed for and of the update frequency. The load only comes up when a
subscription is utilized.
127(
The capacity of the communication bus must also be considered in the
performance calculation. See separate documentation attached the used bus.
Load data is given by a diagram,
. By extrapolation you may obtain the load figure
for an extended number of objects.
First an example and some general comments:
A display with 100 objects from one Advant Controller 450, with an update cycle of 3 sec,
generates a load of approximately 1% in the controller. Use of 7 different object types and
communication module CS513 with a slave CPU is presupposed.
Always present digital signals with event-controlled update in combination with 9 sec cyclic
update, for fast updating on changes while minimizing the load.
The total load in the controller from subscriptions for displays should normally not exceed
20%.
