how to calculate traveltime on a crane?

Hello!

I need to monitor the traveltime of a crane. One solution was mentioned in this Post.

But there i can't divide the traveltimes into load rack and unload rack.

I tried also to use the tree node stats_lastmovetime but without success. There i get a list with equal timestamps. Here it isn't divided (load / unload), too.


Thank you!

Here's an example using a process flow to detect the task start and finish events; some logic to determine if the task sequence is loading or unloading, and a tracked variable "CraneJobDivision" to record when the crane is Emptying or Filling the rack and when it is Idle.craneStats.fsm

Good Morning,

sorry for late answer. my Colleague found a similar solution. He added 2 time-labels "staytime zeit1! and "Staytime Zeit2". There the staytime is calculated. he uses "trackedvariable", too. see screenshots.

Understood - you replace the standard task sequence with a process flow where you can capture the time in the flow, rather than listen to standard task sequences. Glad you found a solution.
