Forceback in maxDNA
significance of forceback attribute in maxDNA.

hey i'm new to the field.I'm at present working on maxDNA system. I just couldn't figure out what the attribute 'Forceback' is for,while defining atomic block parameters. I guess it is used to track the output but i' not sure.

Can anyone explain in detail?

Forceback is the required connection between blocks in order to send values back from the so called "output" side to the "input" side, in order to ensure bumpless transitions and the correct tracking among blocks.

Exmaple: PID basic block is:
- PID block
- Output block (either 4-20ma or PAT, etc).

If you put the loop in manual and set manually an output value, how the PID knows from which position to restart the control action.
That is the forceback action. it writes back a complex value in order to set the PID.

Simple example but is useful a lot more in complex logic.

ForceBack is going to help you if you want to force the PID to some value in Auto Mode, value may be generated in your calc block or in any other way during specific event occurrence and then release it when the event is over. May also be used for Fast Opening/ Closing based on the event requirement
