c++ "Ehmi" tag not working ? + vs2019 c# plugin location ?

Hi,

I started creating some simple HMI to be able to display info from my c++ program.

I made this tagging in my c++ program:
//#port
//#attributes(Output|Ehmi)
//#name(Sim_voltage_HMI)
float32 out_voltage_HMI = 0;

How do I get this value into the HMI. I searched the forum found some talk about it but can't make it work for my application. in the HMI I am using "radial gauge" and would like to show voltage.

I did make it work with HMI tagging when using a local program with ST, but that is not my goal to use that.

 

second question

I see now that in 2020.0 LTS its possible to write realtime C# code. I would like to try this, but I can't locate the installer. Where will I find the new installer ?

Old installer for 2019.0 is here.

    Hey Christian,

    About the eHMI Tag in C++.
    This is a feature that is in preparation but not yet implemented

    Ehmi The variable is visible for the PLCnext Engineer  HMI.
    (Note: This attribute is currently not implemented. Implementation is planned.)


    The old Plugin should be compatible with 2020 FW as well.

    I hope the download for the latest Plugin is available soon,
    kind regards,

    Hi Oliver,

    Thank you for the link. I can see as you say that the "ehmi" is not yet implemented. What would be my workaround for this?  Should I send a C++ program output-port to a IEC61131 program that I create in PLCnext Engineer and then connect this program to the HMI? Or what is the best solution?

     

    I look forward to the release of VS2019 plugin. I wanted to try out the realtime C# program, and I guess that I can't do that with the old plugin for vs2017 ?

    Hey Christian,
    yes forwarding data to IEC through Ports is a workaround you can use.

    you can with the VS 2017 Plugin already create Realtime Functions and Funktionblocks.
    They can be instantiated in any IEC 61131-3 program you create-

    kind regards,
    Oliver

    Hi Oliver,

     

    One additional question. I can see that in C# it's possible to tag input/output ports in programs with tags like "OPC" or "HMI". Does this HMI tag work or will that be the same workaround like for C++ ?
