Conditions for DP1

2.If the flow items is blocked the items divert items to alternate DP3 or DP4.

3.If the flow is cleared items from rack feed to processor by FIFO basis.

4.flow items should follow FIFO and Batch FIFO.

I would remove what you have and instead put 3 photoeyes on the conveyors as outputs of the single decision point (these are ways of referencing - you're not going to close or open these ports).

Then in your decision point I would add a code snippet to the onArrival/Continue (your choice):

Array pes=current.outObjects.toArray();
Object pe;
for (int n=1;n<=pes.length;n++){
    pe=pes[n];
    if (pe.stats.state().value!=PE_STATE_BLOCKED){
        Conveyor.sendItem(item,pe);
        break;
    }
}

This code scales so you could add more PEs and it will consider them in the order they are connected. If the PE is not blocked it will send the item there.

Here's a start, but not the solution. I've created a seqnum label on the source and two process flows to manage the hold/release of items at the merge point. It stops when the next item in the sequence has not been released in sequence from the racks - something you'll need to consider and address.
