I have lift trucks picking from conveyors and placing in racks. That logic is controlled by process flow and works great. There are no connections between the objects in 3D view.
I added a network of nodes for them to follow and connected them as networks nodes usually are but the trucks don't use the nodes at all.
How do I tell them to use the network?
If you insert travel tasks, then the transporter will use the network. The classic load and unload tasks are typically offset travel tasks. Only the standard travel task forces taskexecuter to use networks. If you place a travel before the load task you should set the destination to the nearest network node. The destination of the label "from" is not reachable from the network.
That works. Thanks. But when I try to choose the destination based on the "from" label it doesn't seem to recognize the label.
I put this in the destination field and it says 'invalid task sequence':
if (getlabel(token,"from")=="Conveyor4") return node("NetworkNode4", model());
if (getlabel(token,"from")=="Conveyor3") return node("NetworkNode1", model());
Any ideas?
The content of the label "from" is a node, not a string. You have to compare with the conveyor object.
if(getlabel(token,"from") == node("Conveyor4", model())) return node("NetworkNode4", model());
Thanks. That works !
Last question. It seems I have to specify my destination code in the Travel destination field as well as in the Unload destination field. I just copy-paste it in both places but it seems redundant. If I don't I get an error.
Any way around that?
The Taskexecuter must be connected to the network with an object connection ( a - type) . Drag a object connection form a Taskexecuter to a single Network node of your network. After reseting the model, the taskexecuter is placed over this node. If you move the taskexecuter from the network, a red tether or line is drawn between the network node and your Taskexecuter. If you don't like to see the connections at all, you can switch of the connections in the view properties.
@Patrick Cloutier if your problem isn't solved by the standard procedure could you post an example model to let us look into it and detect what happens there. thx.
I did all that and it doesn't work. See attached file. alpat-nov-2016-v5.fsm
The 2 lifts take piles from the 3 conveyors on the left and place them to one of 25 destinations on the right. But they just won't use the network... Maybe its because I'm picking from conveyors which can't be connected to nodes. I tried adding a bogus queue at the end of conveyors and it still doesn't work.
