What is MOV in Mitsubishi PLC

 what is MOV used for in Mitsubishi PLC

In a Mitsubishi PLC, the MOV (Move) instruction is used to transfer data from one location to another. This can be used to copy values from input registers or data memory locations to output registers or data memory locations, or to move values between different data memory locations.

The MOV instruction is often used in PLC programs to perform tasks such as:

Copying input values to output registers, in order to control external devices or systems.

Storing values in data memory for later use or comparison.

Manipulating values or data structures within the PLC, such as by shifting or rotating the data or by performing arithmetic operations on it.

The MOV instruction can be used with a variety of data types, including bit, word, and double word values. The specific syntax and usage of the MOV instruction will depend on the specific PLC model and the programming software being used.

For example, in ladder logic, the MOV instruction might be used as follows:

MOV X100, Y100

This instruction would move the value of X100 (a data memory location or input register) to Y100 (a data memory location or output register).

In function block diagram (FBD) programming, the MOV instruction might be used as follows:

out1 = in1

This instruction would move the value of in1 (an input variable) to out1 (an output variable).

In structured text (ST) programming, the MOV instruction might be used as follows:

out1 := in1;

This instruction would move the value of in1 (an input variable) to out1 (an output variable).

Overall, the MOV instruction is a fundamental building block of PLC programs, and it is used in a wide variety of applications to transfer and manipulate data within the PLC.
