For example I draw PhotoEye on my conveyor1 and a box is covered PE1 then I want to send my box to other conveyor lines by getting a parameter and replacing agv's port number. I dont how to do it.
How to get parameters between Object and Object?

This is quite a broad question, as there are many different possible solutions to situations like this.
In the attached model I added a pointer label to the queue that refers to the Photo Eye. In the Send to Port option the queue checks the current status of the Photo Eye. If it is not "blocked", the item is send to port 1, otherwise to port 2.
Instead of the pointer label, you could use a centerport connection between the two objects to get a reference to each other.
Or you could use a global variable that gets set by the Photo Eye and read by the queue.
You could also use the "Model.find()" command to get a reference to an object in the model , though if you access it often, it's usually better to store it somewhere instead of having to search for the object each time.
There's probably even more ways but which is "best" always depends on the given situation (which object accesses which other object and how often) as well as personal preference.
A pointer label has advantages over centerports in that the centerport connection number can change if you then add and remove other connections. The centerport reference by number also doesn't make it obvious what is the intent of an expression, whereas a well named pointer label makes it clear which relation you are trying to reference. This improves code/expression understanding and maintenance.
The pointer label also has advantage over find() in that it will still work if you decide to rename the object.
Lastly - note that if you copy/paste groups of objects that refer to each other the pointer references correctly update to the new group of objects. (centerports also do this)
