    I'm new to the PLC world so take it easy with me!  We have a machine that checks the OAL of the parts. On our hmi it only displays the last part measured. We want to display the last 10 or 20 parts measured. The number displayed is a REAL. I'm not sure the best way to keep the history of the REAL number  and than display it on the HMI. Do I use an array?   It is programmed in tia v14. I think it's a 1500 PLC. Thanks!
