85% loading in an AC450 is not a problem. The CPU load of adding 3 signals is very small.
You can use a calculation aspect in the 800xA system. Note that you must subscrbe data at 3 sec or 9 sec intervals from an AC450 or you create a much higher CPU load than just adding 3 signals in a PC program ;)
