【Teaching Video】T5L DGUSII Modbus Master Configuration

rosy

This teaching video is based on the DGUSII platform DWIN OS Modbus RTU master-slave interface program, using the 485 interface. For the general application of DWIN screen as Modbus master, users do not need to program the code, but only follow the video to configure the initialization 22.bin file and configure the trigger conditions for sending read and write instructions.


The resolution of DWIN screen and image is 800*480.

您好，我下载了这个attachment,依照视频改了22文件，成功读取我的"气象多要素百叶盒传感器"的温湿度。

现在我想改GUI,放自己的图，产生32.icl,然后把没在DGUS TOOL生成的bin文件直接从以上拷贝进去。
我这么做了，可是不成功。modbus没有发送。

我要怎么做呢？请问可以指路吗？谢谢。

您好，我看了您的工程，22文件里面没有配置指令，您的联系方式能私信一下吗，方便沟通。

Hi.

I have question.

I want to change display screen number, when PLC 0x100 data has been changed. The screen number should be value of PLC 0x100.
and also,
want to chage PLC 0x200 data when the data at HMI address 0x5000 has been changed. The data at HMI addres 0x5000 should be same as PLC 0x200 data.

Hope to get info from you.

Hi.

I have question.

Hi!

If you follow this configuration guide, and use your HMI as MASTER, you can use instructions like:
①Use 0x03 instruction by mod 00, it will automatically read data from PLC. The 22.bin file content should be like  "5A 01 03 04 01 F4 00 00 00 00 50 00 00 64 00 00", it will keep read PLC 0x100 data(1 word) and write to HMI 0x5000.
②Use 0x06/0x10 instruction by mod 00, it will automatically write 1 or multiple words data from HMI to PLC. Instruction like "5A 01 06 01 01 F4 00 00 00 00 50 00 00 C8 00 00 ", it will keep write HMI data(1 word)  of adress 0x5000 to PLC 0x200.
