This article is about the use of move instruction with the help of TIA PORTAL.<\/p>\n\n\n\n

MOVE instruction plays a huge role in analog programming from changing the speed of the motor<\/a> to changing temperature intervals, etc.<\/p>\n\n\n\n

Move Instruction<\/h2>\n\n\n\n
\"Move<\/figure><\/div>\n\n\n\n

The “Move value” instruction to transfer the content of the operand at input IN to the operand at output OUT1. So the instruction copies the content of operand “TagIn_Value” to operand “TagOut_Value”.<\/p>\n\n\n\n

The parameters on the input and output must be of the same data type. The parameters can also be structured tags (PLC data types). It Copies complete arrays and structures.<\/p>\n\n\n\n

Do follow the below steps to learn how to work with the MOVE instruction.<\/p>\n\n\n\n

Step 1:<\/h4>\n\n\n\n

Open TIA PORTAL. Enter in the programming environment. On the left-hand side from the basic instructions<\/a> menu, you can find a MOVE instruction.<\/p>\n\n\n\n

I have added a MOVE instruction as you can see in the below window.<\/p>\n\n\n\n

On the Input side, I can use a number, or I can use a variable (like MW, MD) which we want to move to the destination.<\/p>\n\n\n\n

So, the input value will go to \u201cOUT1\u201d where you have to define a data type like word, double word, or real.<\/p>\n\n\n\n

Here, I have used the word data type.<\/p>\n\n\n\n

Say we have a value of \u201c10\u201d at the input side, a value of \u201c10\u201d then moves to the destination address at \u201cOUT1\u201d.<\/p>\n\n\n\n

Step 2:<\/h4>\n\n\n\n

Let’s consider an example where I have to turn ON 8 valves<\/a> by pressing the start button. In actual programming, this only happens based on conditions like pushing a button.<\/p>\n\n\n\n

At first, you may think the logic as shown in the below window. Here, when you press the START switch then all 8 outputs are going to energize.<\/p>\n\n\n\n

As a PLC programmer what you need is to make the logic simple, not lengthy, and complicated.<\/p>\n\n\n\n

\"Example<\/figure><\/div>\n\n\n\n

Step 3:<\/h4>\n\n\n\n

As you can see in the below window that I have added move instruction to perform the same task as above.<\/p>\n\n\n\n

In the network, you can see that I have used w#16#ff.<\/p>\n\n\n\n

w#16 is a format you have to add to work with MOVE instruction. The “ff is a hexadecimal<\/a> number, which represents eight 1\u2019s (11111111) in binary.<\/p>\n\n\n\n

When I energize the input, \u201cff\u201d moved to QBO which holds eight outputs (1 byte = 8 bit). So, all 8 outputs will be turned ON as we sent logic “1” to all.<\/p>\n\n\n\n

To reset all the outputs, in the second-line of logic, I have added NOT instruction to inverse the logic.<\/p>\n\n\n\n

When NOT is active it will move zero to QBO, which then turns OFF all the outputs.<\/p>\n\n\n\n

\"MOVE<\/figure><\/div>\n\n\n\n

Step 4:<\/h4>\n\n\n\n

Here, you can see the result in the simulator.<\/a><\/p>\n\n\n\n

when I0.0 is active, then MOVE instruction will move data from \u201cIN\u201d to \u201cOUT1\u201d which in result turning ON all the outputs at the same time.<\/p>\n\n\n\n

\"Step<\/figure><\/div>\n\n\n\n

Step 5:<\/h4>\n\n\n\n

When I0.0 is false, It will move a value of zero from IN to destination location \u201cOUT1\u201d which result in turning OFF all the outputs. (second move instruction block)<\/p>\n\n\n\n
