The load in an Advant Controller 450 caused by a communication with an external computer
using EXCOM is approximately the same irrespective of if the actual controller is a transit node
or a slave node in the communication. The computer is always master.
Reflect the following when you read the load data at different transmission rates (bps) given in
figures below.
•
The load algorithm is quite complex and the straight lines in the figures are practical
approximations only.
•
Limit values for maximum number of messages (with a given number of signals in the
message) is given.
•
A limit value within parenthesis is estimated.
•
You should consider the individual signals included in a data set package in the same way
as AI-, AO-, DI-, DO-signals.
•
To minimize the CPU load and to get high communication throughput you should apply
several signals in each message.
