Net.FTcpSocket?


Rait
 Share

Question

I used Net.FTcpSocket extensively to communicate with devices that use ModbusTCP, Modbus RTU, LON, etc. I no longer see the FTcpSocket method available in HC3. Is there an alternative to pushing raw data to TCP port or is this feature not available on HC3?

There is pretty nice documentation regarding net.TCPSocket class. 

Please login or register to see this link.

 

I have created Modbus On/Off based on FIBARO example. Now i am missing thermostat/recuperation device type.

 

Toggle values 0/1 of Register 101 (40101):

In QDs (QuickApp devices) there is net.TCPSocket() available.

Are you sure about that? There is no code completion/hint about that, only the net.HTTPClient(); method. And when I try to use it, the code just stops.

The above produces the following output:

  • @jakub.jezek Thank you! I can not believe I had not found that documentation yet!

     

    As a bonus I just discovered HC3's Lua supports bit operations natively! 

     

    x&y = AND

    x|y = OR

    x~y = XOR

    ~x = NOT

    x>>y = RSHIFT

    x<<y = LSHIFT

    Hi guys,

     

    I'm strugling now with Modbus reading. Have you encountered following? If you send 2 commands in one button, then you do not get response for 2nd command in HC?

     

    I'm sending 2 strings 2 seconds apart to get data from registers 101 and 207. I'm using PLC Simulator(

    ) till i get to live recuperation unit (getting there in Fall :D). I must say PLC Simulator is nice handy tool

     

    Command i'm sending:

    Sending part:

    Actually HC3 should receive the data. Both responses have correct value.

    for you the best solution would be the Fibaro Premium Service, more.fibaro.com

    @VedranS, I would start with

    Please login or register to see this link.

    and get write and read command from there.

     

    Then with it you would add to strings 0x, so it would look like this:

    Hi @jakub.jezek 

     

    Did you manage to solve the issue with not being able to capture more than one response from the device? I'm currently struggling with the same problem and not making much progress.

     

    EDIT: Well, as soon as I had posted this, I had an idea... and it worked.

     

    So the problem seems to be that using any sort of looping or delays do not let the self:waitForResponseFunction() to trigger. It triggers only once after sending out all the different queries. The solution seems to be putting your individual queries into setTimeout loops. Like this:

     

     

    Please login or register to see this code.

     

    This way I end up with a list of setTimeout loops starting from 30 second interval and with 1 second in between queries. All responses get captured correctly.

    Hi @Rait,

     

    Yes, I did. There was need to use setTimeout() function instead of sleep(). Now my Systemair is working as it should.

    Hello @jakub.jezek,

     

    I have problem to make the same behavior as yours but I failed.

    Can you share your QuickApp with the setTimeout() fonction instead of sleep() ?

     

    Thanks in advance.

    Hi @KanaChan1977,

     

    I will not share whole QA yet. But part below should help.

    It's quite common in protocols to send byte sequences with specific time intervals. It can make sense to define a function that calls other functions with given time intervals - a fibaro.setTimeoutSeries... The function takes a even variable number of arguments; <function1>,<time1>,<function2>,<time2>,...

    like the regular setTimeout, the next time will count from the previous one so we "serialise" the execution - so times becomes delays between function calls.

    It also tries to compensate for eventual time drift...
