• Drag & drop these variables on screen so to build IO fields to them

• Place a button on the screen

• In the button → properties → events → click create the follow c script:

#include "GlobalDefinitions.h"

void OnClick(char* screenName, char* objectName, char* propertyName)

{

//Insert the code starting here

#pragma code ("useadmin.dll")

#include "PWRT_api.h"

#pragma code()

LPTSTR pLogin = GetTagChar("HMI_User_Name"); // Nome do usuário

LPTSTR pPassword = GetTagChar("HMI_User_Password"); // Password

PWRTSilentLogin(pLogin,pPassword);

}

Button (predefined user / password)

• Place a button on the screen

• In the button → properties → events → click call the system functions

  • SetTag (UserName = HMI_User_Name, Value = “John”)

  • SetTag (UserPassword = HMI_User_Password, Value = “111”)

  • In the button → properties → events → click create the follow c script:

#include "GlobalDefinitions.h"

void OnClick(char* screenName, char* objectName, char* propertyName)

{

//Insert the code starting here

#pragma code ("useadmin.dll")

#include "PWRT_api.h"

#pragma code()

PWRTSilentLogin("John","111111");

}

Logoff by button:

• Place a button on the screen

• In the button → properties → events → click create the follow c script:

#include "GlobalDefinitions.h"

void OnClick(char* screenName, char* objectName, char* propertyName)

{

//Insert the code starting here

#pragma code ("useadmin.dll")

#include "PWRT_api.h"

#pragma code()
