Advant Fieldbus 100 Load

Calculation of load for AF100 with a length of max 15,000 m (16,400 yards)
Due to the organization of the Advant Fieldbus 100 scans, some constraints are
imposed on the transmissions. To guarantee message transfer etc., at least 50% of
the fieldbus load is reserved. The remaining load (up to 50%) can be used for S800
I/O station loading and other station loading.
The calculated load of Advant Fieldbus 100 must be equal to or less than 50%.
NOTE! 1 ms cycle time is not allowed.

(1) Readbacks increase the load depending on the cyclicity and with the same amount as the net load at the cycle time.
For Master the cycle time is 1024 which gives 0.009% more load. For MOD the cycle time is configurable.

INSCANT
(2) Total load = (load generated by INSCANT) + (load generated by OUTSCANT)
The total load if INSCANT is 32 ms and OUTSCANT is 64 ms is:
Total load = 1.288 + 0.494 = 1.782%
