I've got a scanner connected to a MicroLogix 1500 and can scan a barcode in, but how do I clear out that number so I scan a different barcode and get that info. Desk has a dent in it from banging my head. Thanks...... 🔨
 
Depends on what you mean by "clear out the number".

I presume that your barcode is going into a string file (ST) location ?

If so, then just move a zero into the first word of it. A zero is used to indicate the end of the string data, like in C: MOV 0 ST9:0.DATA[0]
