When is the AGV.currentCP property updated?

Hi,

I would like to ask a very simple question: when is the AGV.currentCP updated?

I created two similar models with only one different: delay = 0.

Without the delay, the model works perfectly. The redirect command updates correctly the currentCP property (model currentCP_redirect_without_delay.fsm).

With the delay, the model returns an exception because after the redirect command the currentCP isn't valid (model currentCP_redirect_with_delay.fsm).

Where is the mistake?

Thanks in advance.

Software Version:

FlexSim 20.2.2

agv flexsim 20.2.2 redirect currentcp

currentcp-redirect-without-delay.fsm (35.9 KiB)

currentcp-redirect-with-delay.fsm (36.5 KiB)

currentCP will give undefined results when the AGV is moving. You should only access currentCP when the AGV is stopped. In other words, for your purposes, you should only assume that currentCP is updated when an AGV comes to a stop.

Thanks @anthony.johnson!

How can I know which is the last CP for an agv?

You listen for the AGV pre-arrival and then set a label to the involved control point for that pre-arrival event.
