Hello Everyone! I have a quick question as I’m new to PLC programming. I’m currently working on integrating a PID Controller into my ladder diagram and need assistance with implementing the Applied Instruction, specifically the FNC 12 MOVP function. According to the Mitsubishi FX3U manual, I can add the Applied Instruction in five steps. Could anyone guide me through these five steps? Unfortunately, I can’t access YouTube or other media sites due to company restrictions. Your guidance would be greatly appreciated. Thank you!
I discovered a helpful manual at the following link: ftp://81.105.173.212/PLC/Legacy Product/Fx Series/Fx/INSTRUCTIONS/SAT121A.PDF. Within this manual, you'll find detailed information about the MOV instruction, which is the fundamental building block of programming and consists of five essential steps. For instance, as illustrated in Figure 1, when the X000 input is activated, the MOV instruction comes into play. This instruction is comprised of three key parameters: a) **MOV Statement**: This is the primary command. b) **Source Data Specification**: This indicates where the data that needs to be transferred is sourced from. c) **Destination Specification**: This defines where the data will be transferred to. In my experience programming an FX series PLC, the most challenging aspect was correctly inputting the parameters. To use the MOV instruction, you must first choose an output coil in ladder logic. Then, in the designated input area, type a command similar to `MOVP K24 D1250`, where `K24` represents a constant that contains the source data, and `D1250` identifies the destination for the moved data. Remember to include a space before both the 'K' and the 'D' – or any letters that precede the source and destination values. Here is the instruction format to follow: ``` PROGRAM STEP No. INSTRUCTION 0 LD X000 1 MOV 12 K24 D150 ``` I hope this information proves useful to you. Happy programming!
Thank you, Sir. I will follow up with you soon to confirm if I successfully completed the task according to your instructions.
The MOV instruction requires five steps to complete its operation within programming memory.

Hey there! I totally get how tricky it can be starting out with PLC programming, especially with something like a PID controller. Here’s a quick rundown on those five steps for using the FNC 12 MOVP function based on the FX3U manual: First, open your ladder diagram and find where you want to place the instruction. Second, select the Applied Instruction from your instruction set. Then, drag it into your ladder at the desired rung. After that, you’ll need to define the source and destination for your PID parameters within the instruction settings. Finally, don’t forget to test your setup to ensure everything runs as expected. If you run into any issues or need clarification on a specific step, feel free to ask! Good luck!
Hey there! Welcome to the world of PLC programming! To implement the FNC 12 MOVP function for your PID in a Mitsubishi FX3U, start by including the PID instruction in your ladder diagram. Next, you’ll want to set up the necessary parameters for the MOVP instruction, such as the source and destination addresses. Make sure you configure the block correctly with the correct data types and ensure it's linked to your PID settings. After that, insert the MOVP function into your ladder rung where you need it. Don't forget to test the setup in simulation mode if possible, to catch any issues before going live. If you need more details on any specific step, just ask! Good luck!

Answer: 1. Define the PID parameters such as setpoint, process variable, and control output. 2. Use the appropriate Applied Instructions, like FNC 12 MOVP, to handle data movement and control logic. 3. Configure the PID control logic within the ladder diagram. 4. Test and adjust the PID parameters to achieve the desired control performance. 5. Ensure the program is downloaded to the PLC and monitor the system to verify proper operation.
Answer: 1. Open your existing ladder diagram in GX Developer. 2. Select the location in the diagram where you
