它指定了显示对话框的监视器。

如果只使用一个监视器，那么保留默认参数“c”或者指定“1”。

注意可以使用PASSLoginDialog 函数来代替PWRTLogin 或者PWRTLogout 函数。

这个函数需要和函数PWRTLogin 相同的参数。

PWRTLogin 和PASSLoginDialog 函数可以调用登录界面，在上面可以登录或者注销。

函数PWRTLogout 被正确执行并且不调用登录界面。

正确执行后这两个函数都返回“1”。

然而，登录不会等到显示对话框之后。

注意如果使用多个显示器，为了能使登录对话框显示在合适的显示器上，需要WinCC Basic Process Control (OS项目编辑器)。

不使用WinCC Basic Process Control 时，可以指定显示器编号，但登录对话框始终显示在第一个显示器上。
