Dynamic Parameters

In Mervis IDE, dynamic parameters allow you to query the system for real-time diagnostic information.

The dynamic parameter stats.communication.proxy.status is used to retrieve the current connection state of the communication proxy.

You can retrieve this status using the dynpar.trygetdynamicparamint function in your ST program:

program main
    var
        result : dint;
        strParam : string;
    end_var
 
    strParam := "stats.communication.proxy.status";
    dynpar.trygetdynamicparamint(strParam, value => result);
end_program

The result variable will return one of the following integer values representing the proxy's current state:
