Hello WKLA , FB you have shown uses Q06 CPU , but you are using "Hardware: Q03UDE CPU with Ethernet interface. Software: GX Works 2." Does it function OK ?

You can protect your routines by using source protect facility of RSLogix5000 . You need to create a key eg ram.dat and use it just like license, routine is accessable/viewable only if key is present at the given location. It works , I regularly use this . Shriram Pendse.
