Setting Multiple Outport Input Conditions

From the source conveyor, item type 1 goes to the conveyor connected to the sink, and the rest goes to one of the 2, 3, 4 rails...!

Here I want to go one step further.
As shown in the picture below, one of the rails 2, 3, and 4 is full and often does not receive items from the source conveyor. (For example, lines 3 and 4 are empty, but lines 2 are often full and cannot enter the entire line.)

So I want to put lines 2, 3 and 4 evenly so that they don't get stuck in certain places. If each line has more than a few items, I want to create a trigger to go to another line. (or photoye block trigger etc...)

If you want to follow a strict pattern to send them evenly then you can use the output of the conveyor minus the number sent to the sink and the function fmod() to determine the port:

if (item.Type == 1){
   current.port1qty++;
   return 1;
}
int numOut=current.stats.output.value-current.port1qty;
int port=Math.fmod(numOut,3)+1;
return port;

For this I've added a label to the exit transfer called port1qty which is set to zero on reset.

Um... That's a good idea. I don't put the lines 2, 3 and 4 in order. Items should be evenly included in all lines 2, 3, and 4. If items are evenly included in each line and a certain line is blocked, we should make sure to supply them to other lines.

You could read the content of the connected conveyors and choose the one with the least items on it as the output direction.

need-limit-condition-fm.fsm

The downside to this method is that items in transit are not counted towards the content. So using a counter label might be a better option.

Also, if the conveyors have different length, it would be better to determine the available capacity per conveyor and choose the one with the highest value.
