vcTransportLink

Transport link is a single-directional logical connection between two transport nodes that defines navigability and transportation parameters for a specific flow group of products. Each link has to be associated with a vcTransportController that implements the link and can add its own custom properties to it.

Transport links are owned by a vcTransportSystem and thus are created and deleted through its methods.

For easier tracking of transport graph navigability changes, only the Implementer can be changed after the link has been created. To change the other properties of a transport link user needs to create a copy and delete the original instead. Any dynamically created properties can be edited at will, but adding and removing properties is usually only done by the implementing transport controller.

Properties

Name	Type	Access	Description
Source	vcTransportNode	R	The transport node to start moving from.
Destination	vcTransportNode	R	The destination transport node.
Implementer	vcTransportController	RW	The controller that will take care of moving the product through this link. Note that when reassigning the implementer, the transport controllers usually modify the link’s properties immediately in event handlers.
SupportedGroup	vcProcessFlowGroup	R	Only product types belonging to this flow group can travel through this link.
Properties	List of vcProperty	R	Gets the properties that have vcProperty implementation.

Methods

Name	Return Type	Parameters	Description
createProperty	vcProperty	vcProperty property	Creates a new dynamic property to this transport link.
getProperty	vcProperty	String propertyName	Returns a property from this transport link.
deleteProperty	None	vcProperty property	Deletes a property from this transport link.

Examples

Example. Reset transport time to 10s for all.

# transport links using interpolation.
from vcScript import *
sim = getSimulation()
tsystem = sim.ProcessController.TransportSystem
# Get interpolating controller
icontroller = None
for controller in tsystem.Controllers:
  if controller.Type == VC_INTERPOLATINGTRANSPORTCONTROLLER:
    icontroller = controller
    break
# Change links
for link in tsystem.Links:
  prop = link.getProperty('TransportTime')
  if link.Implementer == icontroller and prop:
    prop.Value = 10.0
