Hi. I have a problem with MODBUS TCP MASTER. I treid to read HR in range 3027-3037 but I cannot read them. I have modbus slave chanel with offset 0x3037. I checked what I read and it looks like I am reading HR in range 1-10. What I am doing wrong.

Post by mehakfatima on Need Help Configuring Energy Analyzers via Modbus TCP & RTU (RS-485) in CODESYS 3.5 ^{CODESYS Forge talk (Post)}
Hello everyone, I am currently working on reading data from energy analyzers using Modbus TCP and RTU (RS-485). In my previous software, I used the following method to add slave devices (i have attached the image) and configure registers: Add the Modbus slave device. Configure the communication parameters (baud rate, parity, etc.). Define the registers and their addresses for data retrieval. Now, I am trying to achieve the same in CODESYS 3.5, but I am not sure how to configure the Modbus master, add slave devices, and set up the registers properly. If anyone has experience with Modbus TCP/RTU setup in CODESYS 3.5, I would really appreciate your guidance! A step-by-step explanation or any references/tutorials would be extremely helpful.
