SFC dynamic behavior limits
These are options which determine the amount of memory, allocated by the target at initialization time, to manage SFC Dynamic behavior (i.e. token moving).
The amount of allocated memory is calculated as a linear relation with the number of SFC POUs:
NbElmt = GainFactor * NbOfSFC + OffsetFactor
Alloc Mem (bytes) = N * NbElmt * sizeof(typVa)
A simpler, but more approximate definition is:
Here, an action refers to an N, P1 or P0 action linked to a step.
If the available memory is not enough at a specific moment:
In target versions 4.03 and older, the resource is not set in ERROR mode.
