[Question]DWIN HMI T113 39 Series Query

Vijay

I'm working in DWIN HMI Allwinner T113 39 Series Part Number: DMT80480T050_39WTC. I'm Interfacing STM32 controller to stream multiple data vis RS485 UART's using Modbus communication protocol but i'm facing many difficulties. The software being used is HMI Software as it is a DMT based T113 Linux 5.4 display i cannot use DGUS software and use T5L method, due to the less availability on the T113 based DMT display. I can't able to even flash my modbus slave HMI addressed UI onto the Display. As there is no development resources available for this i'm finding difficult for the development. If you have any
1. Related documents for how to configure HMI for MODBUS Protocol slave in RS485 or RS232 electrical medium.
2. HMI addressing is not well defined, Local HMI usage confirms local Addressing and doesn't involves in any communication transactions. For that i need proper MODBUS addressing space for particular "DMT80480T050_39WTC" display.
3. What exact address conversion, exists between HMI address notation and Modbus PDU address notation to configure in HMI software - HMI 2.0.49.
4. Also the HMI software doesn't seems to be fully licensed even after i got overseas activation code and made it for official mode.
5. Additionally, there is no Modbus address mapping table available within the DWIN HMI Software.
I would appreciate if you can help me with these details, if possible guide me through how can I get related documents, tutorial videos, communication protocol documents on How to configure Modbus in HMI as slave and interface PLC.
Thank you.

I appreciate if you can give information regarding this and assistance as soon as possible. Thank you.
