Using c# script to control logic

Can you tell me under what circumstances Value, status.Value, status.ValueOverride will change to true respectively?

here is my code 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using game4automation;
using NaughtyAttributes;

public class PickBlank1A : ControlLogic
{
public bool PickProduct1A_On = false;


[Header("Signals")]
public PLCOutputBool StartPathPick; //初始态移动机械臂抓取
public PLCOutputBool StartPathReturn; //成功抓取后返回标准位置

public PLCOutputBool Pick;
public PLCOutputBool Place;
public PLCInputBool RobotSensorOccupied;
public PLCInputBool PathEnded;

private void Start()
{
PickProduct1A_On = false;
}

private void Update()
{
//当开启时，启动机器人路径
//Starts the robot path when turned on
if (PickProduct1A_On)
{
StartPathPick.Status.ValueOverride = true;
}
//当路径动作结束时 => 夹取传感器被占据 => 开启信号未复位时，进行夹取
//Clamping when the path action is finished => Clamping sensor is occupied => Clamping is performed when the open signal is not reset
if (PathEnded.Status.Value && RobotSensorOccupied.Status.Value && PickProduct1A_On)
{
StartPathPick.Status.ValueOverride = false; //路径信号复位 Path signal reset
//夹取 这里注意Grip夹取时使用的是Value而不是ValueOverride
Pick.Status.ValueOverride = true;
Pick.Status.Value = true;
}


//当夹取的路径走完后，判断是否夹取成功，成功夹取了再执行返回标准位置的路径
//When the clamping path is completed, determine whether the clamping is successful, successful clamping and then execute the path back to the standard position.
if (PathEnded.Status.Value == true && Pick.Status.ValueOverride == true && Pick.Status.Value == true )
{
StartPathReturn.Status.ValueOverride = true;
//返回标准位置后，该单步任务结束
//After returning to the standard position, this single-step task ends
PickProduct1A_On = false;
}
}

private void SwitchPick(PLCOutputBool pick)
{
pick.Status.ValueOverride = !pick.Status.ValueOverride;
}
}

You should always use signal.value = true or signal.value = false;

See for example the scripts in the demo model - for example this code:

Sensor Occupied is for example a PLCInputBool Signal

void FixedUpdate()
{

    if (SensorOccupied.Value == false && On && ButtonConveyorOn.Value == true)
    {
        StartConveyor.Value = true;
    }
    else
    {
        StartConveyor.Value = false;
    }

    LampCanAtPosition.Value = SensorOccupied.Value;
}
