get_input_register_int

This function reads an integer value from the controller input register using the specified register address. It is typically used for PLC I/O register monitoring in Ethernet-based environments.

Definition
DRFLEx.h within class CDRFLEx, public section

bool get_input_register_int(unsigned short address, int& out_val, int timeout_ms = 300) {
    return _get_input_register_int(_rbtCtrl, address, &out_val, timeout_ms);
};

Parameter

Parameter Name	Data Type	Default Value	Description
address	unsigned short		Input register address (int type, 0~23)
out_val	int&		Input integer value to read
timeout_ms	int	300	Timeout in milliseconds

Return

Value	Description
0	Error: failed to read input register int
1	Success: input register int read

Example

#include "DRFLEx.h"
#include <iostream>

using namespace DRAFramework;

int main() {
    CDRFLEx robot;

    const char* ip = "192.168.137.120";
    if (!robot.open_connection(ip)) {
        std::cout << "Failed to connect: " << ip << std::endl;
        return 1;
    }

    // Read int (timeout 300 ms)
    // Initialize to 0 to indicate “not read yet” if the call fails.
    int out_int = 0;
    robot.get_input_register_int(0, out_int, 300);
    std::cout << "addr=0, out_int=" << out_int << std::endl;

    robot.close_connection();
    return 0;
}

This example reads the input register integer value at address 0 (Int_Input_Register[0]).
