Help with PLC querie for palletizing registers

    Hi there, I am programming a PLC and HMI for use with PalletPro and a FANUC robot. We want to give our operators a visual display of the palletizing status. I.e which laye,r how many units in layer on pallet. Can Anyone help with this? I see position and status registers, but I do not know how to query without a cycle stop to keep layers updated as it indexes. Any help is greatly appreciated!

    Approved the thread.

    Leviafun - Thank you!

    Yes, I have figured out the comms and sending G1 data for load and pallet info and stop cycle, etc. But what you said makes sense. So... I make a program on the robot side to monitor the registers that I need and it will respond with the group out that I designate? Do I need to add that into the WCELLMON.TP as well? or I guess, how do I run it concurrently with Palletpro?

    I usually setup a group output for each piece of data I want to monitor. I just set the outputs in PLONPAL.TP after calling open_tool and pulse an output so that the PLC knows when to update the HMI:

    Code
     280:   ;
 281:  GO[2:0:Current Station]=R[4:Current Pallet] ;
 282:  GO[3:0:Current Layer]=R[5:Current Layer] ;
 283:  GO[4:0:Current Unit]=R[6:Current Unit] ;
 284:  GO[5:0:Current Unit Load]=R[2:Current Unitload] ;
 285:  DO[80:OFF:Upd Layer/Units]=PULSE,1.0sec ;
