Modbus Integration with Daikin DIII-Net - Sumit - 28.09.2023
We are trying to integrate Daikin DIII Net Modbus with Logic Machine, but we are unable to control the AC using the scripts (same has been attached). I have attached the Modbus Addressing List also in Excel format. We have tried with and without RTU settings in Modbus Tab in LM, Screenshot for the same has been attached.
We need your help regarding the same and also it will helpful if we can get DIII-Net's Modbus Profile.

You can't access a single port from multiple scripts at the same time, it will lead to errors. Enable RTU 1 and use mbproxy: https://forum.logicmachine.net/showthread.php?tid=387&pid=1953#pid1953
You might need to subtract 1 from the documented addresses as LM uses zero-based Modbus addresses. Use read test to check if addresses are correct.

I have attached the backup of LM (Srinivasulu Pola) from Site-01 in reference to the previous mail where I have attached the scripts for AC On/Off and Temperature Setpoints for Site 02. In the Site-01 we have the same configurations for Modbus Integration, and we have used the same scripts for controlling the ACs. We don't see any issues with the working of the scripts with Modbus Device in the Site 01 but the same we are not able to control any ACs with same scripts. Please help us to understand the issue in the Site 02.
Note - Site 01 - Up and running from past 2 years.
Site 02 - New Installation

You are just lucky, this implementation is not correct. Please fallow admin instructions.
