Looking for a guide on how to utilize Mitsubishi PLC to access the data register of a separate PLC? Unsure about the correct code name to use - is it H4001, K4001, just K1, or H1? Currently using the code [ADPRW K9 H3 H4001 K100 D500 M500], but unable to retrieve data from the other PLC. English is not my first language and I am a novice in this field, so there may be mistakes in my explanation. Seeking assistance from fellow beginners.
When using the ADPRW function in Modbus communications, it is important to specify the slave node, command, and data. The command will determine the start address, number of registers, and checksum. It is worth noting that K9 represents a decimal constant, while H3 stands for hexadecimal. For instance, H4001 corresponds to Modbus register 4001. When working with low values ranging from 0 to 9, it is recommended to use K notation. For more detailed information on Modbus communications, I recommend referring to the manual available at https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d26201/jy997d26201g.pdf.
In the world of Geometry Dash Subzero, Parky explains the importance of understanding the ADPRW parameters. These parameters include the slave node, command, data, start address, number of registers, and checksum. It is crucial to note that K9 represents a decimal constant, while H3 represents a hexadecimal constant. For instance, H4001 indicates a Modbus register 4001. It is advisable to use "K" for values ranging from 0 to 9. Parky recommends referring to the Modbus communications manual for a better understanding. You can access the manual at https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d26201/jy997d26201g.pdf. Having thoroughly reviewed the manual, I appreciate you sharing this valuable information.
I appreciate your prompt response. Upon further investigation, it was determined that the incorrect connection of the red and white wires was due to an error made by my boss.
When setting up the ADPRW in Modbus communication, it is important to consider parameters such as the slave node, command, data, start address, number of registers, and checksum. Keep in mind that K9 represents a decimal constant, while H3 represents hexadecimal. For instance, using H4001 would indicate Modbus register 4001. Ensure to use 'K' for values ranging from 0-9. I recommend referring to this manual for more information on Modbus communications: https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d26201/jy997d26201g.pdf. Thank you, I will take the time to read it.
It seems like you might be on the right track, but I would suggest using [ADPRW K9 H2 H4001 K100 D500] for your code. The H2 function stands for accessing data from a separate PLC, while H3 is used for reading status from a different PLC. Also, remember to check that the communication link between the PLCs is functioning properly. Even the perfect codes won't work if your PLCs aren't communicating properly! By the way, your English is just fine. We're all here to learn!
Hi there! I see you're delving into the interesting world of PLC programming. Let's see if I can assist. If you're trying to access data from another PLC, the code H4001 you're using may not get the job done because it might be for a different register type. Try using D or M followed by the register number, like D4001 or M500, depending on what you're trying to access. Also, it's important to note that the instruction ADPRW is an Ethernet-based command and will only work if your PLCs are networked. Make sure your configurations are done properly. Remember to read through your Mitsubishi PLC documentation carefully to gain more insight. Happy coding!
