In the previous lesson titled Shift Left Word and Double Word Part 2 we discussed how we can use the Shift Left Word and Double Word instruction and how this instruction works more like a multiply instruction. In this video we will become familiar with how to turn on PLC outputs in sequential order using the SHL Instruction. This lesson will show you how you can shift individual bits within a word to the left with a simple push of a button. This instruction will be very handy when you want to track parts of a process while it goes through its various stages of assembly, or you want to track bottles as they travel down sections of a long conveyor belt. Open up this lesson and let’s get started.
