Virtual Device Feedback


fibarojiang

Question

Hello, I can help you do a 485 signal feedback can receive virtual equipment? I have a power window controlled by 485, and now I can achieve one-way control, does not mean that I can correctly know whether it is open or closed state, can help me modify my code?

Please login or register to see this attachment.

 I would like to know if I really open the need to detect the return value of the implementation of 485 communication,“平开打开”

Hi @fibarojiang

Could you expand a bit more on what you are trying to achieve and what you have tried to date

How is the 495 device connected to the network/HC2 ? - are you using a global cache itach device or something similar

 

I haven't any experience with 485 but did find the following two posts

Did you get a chance to look at these ?

 

It might be worth changing the post title to something closer to the problem you are trying to solve

    @fibarojiang

    你能扩展一下你想要实现什么和你迄今为止已经尝试过的

    如何将495设备连接到网络/ HC2? - 你使用全局缓存itach设备或类似的东西

     

    我没有任何经验485,但发现以下两个职位

    你有机会看看这些吗?

     

    可能值得将帖子标题更改为更接近您尝试解决的问题

     

     

     

     

    Thank you, I have a TCP protocol to 485 equipment, I have been able to use HC2 to "TCP to 485 device" to send data signals to normal control equipment, but I would like to edit a virtual device can receive data feedback, So that the real meaning of the control device is the implementation of my order.

    If I understand you correctly you want to send a command to the 485 device and then receive status /confirmation of the command execution or change in status ??? 

     

    What's the TCP-485 device and do you know if it's capable of sending status back ?

    谢谢@fibarojiang

     

    如果我正确理解你想要发送一个命令到485设备,然后接收状态/确认命令执行或更改状态? 

     

    什么是TCP-485设备,你知道它是否能够发送状态?

     

    I have to be able to, because I sent the data received in the device will reply to me a data, such as the implementation of the return 1, did not return the data 0, tcp-485 is converted through the network tcp protocol 485 protocol can be received to the equipment on.

    Could you share  the model number or picture of the tcp-485 device ?

    Hi @fibarojiang

     

    Sorry - I don't know what to suggest as I have never worked with a TCP/IP-RS-486 convertor before

    The unit you have is UTEK UT-6720 but I cannot get the datasheet pdf as I get a malware warning.

    I read some of the other posts on 485 and it seems many of them are just one way communications

     

    Two things I recommend so that others may be able to try and help you....

    Go to your first post in this thread and change the title from Virtual devices to TCP/IP - RS485 query 

    this may attract other forum users who may be able to help

     

    Publish a copy of datasheet if you have it in english to the post

     

    -f
