Visual Cue	Narration
Slide 1:	Welcome to the spoken tutorial on Move Instruction.
Slide 2: Learning Objectives Move (MOV) instruction	In this tutorial, we will learn about working of Move instruction
Slide 3: System Requirements Ubuntu Linux 18.04 OS LDmicro	To record this tutorial I am using: Ubuntu Linux 18.04 operating system LDmicro
Slide 4: Pre-requisites Working of One Shot and Arithmetic instructions. If not, please refer to the relevant tutorials from Home | spoken-tutorial.org	To follow this tutorial, you should know the working of One Shot and Arithmetic instructions. If not, please refer to the relevant tutorials in this series on this website.
Slide 5: MOV instruction MOV instruction copies the value of the source variable to the destination variable.	MOV instruction copies the value of the source variable to the destination variable.
	Let us see the working of Move instruction in LDmicro.
Open LDmicro	Open LDmicro.
	We will create a virtual counter in this tutorial.
Click Instructions -> Insert Contact >> Place the cursor to the right of the contact >> Click instructions -> Insert OSR >> Place the cursor to the right of OSR >> Click Instructions -> Arithmetic instructions -> Insert ADD	Please follow the steps as shown here. First, insert a Contact. To the right of it, insert an OSR. Next, insert ADD instruction to the right of OSR.
Double-click on the contact >> Type switch in the name box >> Click OK button	Rename the Contact as ‘switch’.
Double click on ADD	Double click on the ADD instruction.
Type in the destination and ‘is set as := ‘ columns ‘vcounter’	Set the destination and first operand to ‘vcounter’. ‘vcounter’ means virtual counter.
Type 1 in ‘+:’ in the column >> Click the OK button.	Second operand is by default 1. Don’t change it. Click the OK button.
	We will now check the working of this logic.
Click ‘Simulate -> Simulation mode’ >> Click ‘Simulate -> Real-time simulation’	Let us turn ON the simulation mode. For that, click Simulate and then on Simulation mode. Next, start real-time simulation as shown.
Highlight column state in the I/O list	Observe the state of Xswitch and vcounter in the I/O list. Initially the state of Xswitch and vcounter are 0.
Double-click on Xswitch in the I/O list	Change the state of Xswitch to 1.
Highlight the state of vcounter Double-click on Xswitch in the IO list	We can observe the state of ‘vcounter’ changes from 0 to 1. Change the state of Xswitch to 0.
Double-click on Xswitch in the I/O list	Again change the state of Xswitch to 1.
Highlight the state of vcounter	We can observe the state of ‘vcounter’ changes to 2.
	This means that ‘vcounter’ has the count of number of switch presses.
	Just like a counter which tracks the number of switch presses.
	What if we want to reset the count? Let us see how to reset this count value.
Click on Simulate >> Click on Halt simulation Click on Simulate >> Click on Simulation Mode	Turn OFF the simulation mode. For that, click Simulate and then on Halt Simulation. Then click Simulate and Simulation Mode.
Click Edit -> Insert Rung after	Insert a rung below as shown.
Place the cursor in the new rung >> Click Instructions -> Insert Contact >> place the cursor to the right of the contact >> Click Instructions -> Insert MOV	Next we have to insert a Contact and MOV instruction in the new rung. For that, place the cursor in the new rung. Click on Instructions and then Insert Contact. Place the cursor to the right of the Contact. Click on Instructions and then Insert MOV.
Double-click on the contact >> Type reset in the name box >> Click OK button	Rename the Contact as ‘reset’.
Double-click on the MOV instruction >> Type vcounter in the destination column >> Type 0 in the source column >> Click the OK button	Double click on the MOV instruction. Set the Destination variable as ‘vcounter’ and Source variable as 0.
	Again start real-time simulation as shown.
Double click on Xswitch in the I/O list for 6 times.	Increase the count value, that is, the value of ‘vcounter’ to 2. It can be done by changing the state of Xswitch from 0 to 1 for 2 times.
Double-click on Xreset in the I/O list	Now change the state of ‘Xreset’ to 1.
Highlight the state of vcounter	We can observe the value of ‘vcounter’ changes to 0. Just like resetting a counter.
	Thus, Move instruction copies the value of source to destination variable. Remember that source can be a variable too.
Click on Simulate >> Click on Halt simulation Click on Simulate >> Click on Simulation Mode	Turn OFF the simulation mode as shown.
Click on File >> Click on Save >> Go to Desktop/LDmicro folder >> Rename it as ‘move.ld’ >> Click on Save	Save the ladder diagram as move.ld.
	This brings us to the end of this tutorial. Let us summarize
Slide 6: Summary In this tutorial, we learnt about working of Move (MOV) instruction	In this tutorial, we learnt about working of Move instruction
Slide 7: Evaluation Destination can be either a variable or a constant. True False Source can be either a variable or a constant. True False	Here are some self assessment questions for you. 1 .Destination can be either a variable or a constant True or False 2. Source can be either a variable or a constant. True or False
Slide 8: Answers 1 - False 2 - True	Now let us look at the answers. The answer to the first question is False. The answer to the second question is True.
