I want to monitor the current stay time of the item on conveyor3 and divert the next flow item to conveyor2 if the staytime is more than set value. The main issue is I want to know how to monitor the current staytime of the flow item on conveyor. Could anyone help me on this? Thanks. StayTime.fsm
You can write the entry times of items to a label on the conveyor and refer to them later when deciding where to send an item.
In your model, you have one exit transfer per connection. This means that the decision of where to send the item has to be made before the item reaches the end of the conveyor and the item has to be send to the respective exit transfer.
If both connections belong to one exit transfer, the decision can be made in its Send to Port field. Doing this, in conjunction with the extra Entry Space you added to Conveyor3 will have additional items automatically be send to Conveyor2 with the First Available Send to Port logic.
Another way to control the input could be to use a Photo Eye whose block time is set to some value greater than 0. If the Photo Eye stays blocked until its state actually changes to blocked (as mandated by the block time), the triggers can be used to close/open the entry transfer.
once an item enters a conveyor, Model time - entry time will be written into a label. Since the model time keeps changing. I believe the label value will be increasing. I want to make a decision if the label value is more than 100sec (For example). Could you please help me script? Thanks.
