Dynamic Part Identification

Hello,

I am using VC 4.10 Professional

I am working on a simulation with 6 different part types. I have a feeder with distrubuted part creation based on daily/yearly production numbers. I need to identify the part that has arrived on a specific process node to then either use If or Switch statements to call correct cycle time based on part.

I am just looking for some guidance on where to start or look into.
