get_state_led_rule

This function retrieves the current LED color rule that is applied to the robot arm’s state LED.

The return value represents the currently active LED color index according to the predefined LED color configuration.

Definition
DRFLEx.h within class CDRFLEx, public section (line 997)

unsigned char get_state_led_rule()
{
    return _get_state_led_rule(_rbtCtrl);
};

Parameter
None

Return

Value	Description
0	Off
1	Red

6	Cyan
7	White

Example

#include "DRFLEx.h"
#include <iostream>
using namespace DRAFramework;

int main() {
    CDRFLEx Drfl;

    // Get the current LED color rule (0–7)
    unsigned char ledRule = Drfl.get_state_led_rule();

    // Display the meaning of the LED rule
    switch (ledRule) {
        case 1: std::cout << "LED indicates: GREEN — normal operation.\n"; break;
        case 2: std::cout << "LED indicates: YELLOW — caution or waiting state.\n"; break;
        case 4: std::cout << "LED indicates: BLUE — system ready.\n"; break;
        case 7: std::cout << "LED indicates: RED — error or protective stop.\n"; break;
        default: std::cout << "LED indicates: UNKNOWN or custom rule (" << (int)ledRule << ").\n"; break;
    }

    return 0;
}

This example retrieves the current LED rule value using get_state_led_rule() and prints a corresponding message describing the robot’s current LED status. It allows the user to interpret the LED color state, such as green for normal or red for error, for quick visual diagnostics.
