Learn how to utilize a Mitsubishi PLC to access the data register of a different PLC. Unsure of the correct code name to use, whether it's H4001, K4001, K1, or H1? Current method is [ADPRW K9 H3 H4001 K100 D500 M500], yet unable to read the data register value of the other PLC. English is not my primary language, and I'm a beginner in PLC programming, so there may be mistakes in my explanation. Any assistance for a beginner would be appreciated.
The ADPRW instruction involves a slave node, command, data (dependent on the command), start address, number of registers, and checksum. When using the Modbus protocol, K9 represents a decimal constant and H3 represents a hexadecimal constant (e.g. H4001 for Modbus register 4001). It is recommended to refer to the manual for detailed information on Modbus communications: https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d26201/jy997d26201g.pdf.
Geometry Dash Subzero​ Parky recommended familiarizing oneself with the ADPRW parameters, which include the slave node, command, data, start address, number of registers, and checksum. It is important to note that K9 represents a decimal constant, while H3 represents a hexadecimal constant. For instance, H4001 corresponds to Modbus register 4001. It is advised to utilize K for values ranging from 0 to 9. Detailed information on Modbus communications can be found in the manual provided: https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d26201/jy997d26201g.pdf. I have thoroughly reviewed the manual and appreciate you sharing it.
I appreciate your prompt response. It turns out my boss mistakenly connected the red and white wires.
Parky advised on the necessary parameters for Modbus communication, such as the slave node, command, data depending on the command, start address, number of registers, and checksum. It is important to note that 'K9' represents a decimal constant and 'H3' signifies a hexadecimal value (e.g. H4001 corresponds to Modbus register 4001). It is recommended to utilize 'K' for lower values ranging from 0 to 9. For further information, please refer to the manual on Modbus communication available at https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d26201/jy997d26201g.pdf.
Hello! Don't worry, we're here to help and your explanation seems pretty clear! From my experience, Mitsubishi PLCs usually use the K series directly followed by the number to denote a specific data register. So, in your case K4001 should be the correct code name to access the data register. However, you also need to ensure you've configured the other PLC to allow remote data access, and the addressing of the second PLC is set correctly. Keep practicing and you’ll get the hang of it in no time!
Hello there! It's fantastic that you're diving into PLC programming; it can be a bit confusing at first, especially with the language barriers. As for your query, could you please clarify which series of Mitsubishi PLC you are using? Because if you are using a Q series Mitsubishi PLC, for instance, you would typically use the keyword 'D' for data registers (like D4001, not H4001). I also noticed in your method that you're using 'H3', which usually defines the size of the data that's going to be read, so make sure this matches up correctly with the data size you're aiming to read. However, without knowing the exact model of your PLC it's hard to give the most accurate advice. Hang in there, this field has a learning curve, but it gets more intuitive with time!

Answer: 1. What code name should I use to access the data register of a different PLC using a Mitsubishi PLC? - The correct code name to use when accessing the data register of a different PLC using a Mitsubishi PLC may vary depending on the specific PLC models and communication protocols involved. It is recommended to refer to the documentation or manuals provided by both PLC manufacturers for the accurate code name.
Answer: - As a beginner in PLC programming, you can start by double-checking the communication settings, addressing format, and code syntax used in your program. Additionally, seeking assistance from online forums, PLC programming communities, or consulting with experienced professionals can help you troubleshoot and resolve issues with reading data registers from other PLCs.
Answer: - It is understandable that English may not be your primary language, which can sometimes lead to confusion when working with PLC programming instructions. To overcome language barriers, you can use online translation tools, seek out resources in your native language, or reach out to communities where multilingual support is available to ensure a clear understanding of PLC programming concepts and instructions.
