Manual

2.2

Licencing models

The following licence models of the firmware are available for the Thin Clients:

• Basic

Basic licence for establishing remote connections, configuring the firmware and for

importing and exporting settings.

• Pro

Licence extension for using and managing applications, using multiple parallel

remote connections, importing and exporting settings and the support of the

Remote HMI Device Manager.

2.3

Configuration file

The configuration file contains the device parameters and the settings of the Thin

Client. They can only be opened at the Thin Client.

The "RemoteHMI.config" configuration file can be exported to the root file of a USB

mass storage device or a network directory. The exported file is encrypted and can be

imported after a reset or into another device, for example (see Import and Export).

2.4

Supported remote protocols

The HMI operating stations and the Industrial Box PCs are integrated as Thin Clients

and use the available network resources. Depending on the network architecture and

access authority level, a remote connection can be established via the IP address to

any Ethernet station. The firmware supports the Remote Desktop Protocol (RDP),

Virtual Network Computing (VNC) and Keyboard Video Mouse over Internet Protocol

(KVM over IP). The Thin Client can use the firmware to call up applications installed

on the connected workstations or installed on virtual servers.

The illustration shows a redundant virtual network. It connects Thin Clients via an

RDP, VNC or KVM-over-IP connection with workstations and servers. In such a

network, every Thin Client can access connected systems and call up applications

from there.

Remote HMI

Manual

2.4.1

RDP

The Remote Desktop Protocol (RDP) is a protocol for remote access. It can be used

to display and control screen content of a remote workstation. RDP is an integral part

of all Windows operating systems.

A special session is started on the server for the RDP access, and only the connected

client can access this session.

The size of the displayed screen content is determined on the Thin Client's display

size. If the screen content is only displayed on one half of the Thin Client it will be

scaled accordingly.

A Windows server is required for several RDP connections to access one server. A

client access licence is required for each client to access and connect to the Windows

server. Licencing depends on the operating system of the server.

Either the computer name or the server IP address can be used for addressing.

If you want the option of redundant connections we recommend you use the DNS

naming system.

2.4.2

VNC

Virtual Network Computing (VNC) is a platform-independent server system. VNC

operates according to the Client-Server model.

The VNC service displays the screen content of a remote PC (server) on a local

computer (client) The client sends the keyboard and mouse actions to the remote

server. This way, the client can use the resources, applications and programs of the

server.

The server's display size determines the size of the displayed screen content. If the

server display screen ratio is different to that of the Thin Client, the screen content will

be compressed or displayed with black edges.

VNC allows multiple access to the server. The display of the clients is then

synchronised.

The VNC service must be installed on the remotely controlled PC (host). The Thin

Client accesses the VNC server via a VNC viewer application. The installation and

configuration of the VNC system on the server and the client requires administrator

access authority. The VNC communication between server and client does not require

this level of access authority.

VNC services are available from various providers. Depending on the VNC server,

these systems have different functionalities.

For detailed information and a description of the VNC service, please refer to the

documentation of the provider.

In order to be able to establish a VNC connection, the VNC server system must be

activated on the host. The VNC service acquires the IP address needed for this

connection from the settings of the PC's network connection. Depending on the

configuration, the IP address is specified manually or allocated by a DHCP server. In

the firmware's address book, this IP address is defined as the server IP of the VNC

connection.

The way this connection is established depends on the settings of the VNC server and

can either be

• a direct connection that is not password-protected

• a connection with VNC password

• a connection with Windows password

2.4.3

KVM over IP

KVM over IP provides remote access to keyboard-video-mouse systems (KVM). With

these systems, a workstation is connected with keyboard, mouse and screen via an

external KVM-over-IP box. The KVM-over-IP box is integrated into the network via an

Remote HMI

Manual

Ethernet interface. Data transmission is via the VNC protocol. A VNC service has

been installed to establish the connection. The workstation that is part of the KVM

system does not require a network connection or a software installation.

2.5

Security concept

2.5.1

System security

The Thin Client has been designed as a closed system based on Windows® 10 IoT

Enterprise 2016 LTSB.

As a standard, the Thin Client comes equipped with the Windows 10 IoT Enterprise

operating system and activated Windows 10 LTSB (Long Term Servicing Branch).

If Windows 10 LTSB is not activated (after a reset, for example), it can be activated

under menu item Maintain (see Activating windows).

We recommend you activate the firewall and virus protection and permit all necessary

security updates.

Any further measures to protect the process network are the responsibility of the

operator of the facility.

Manual

2.5.2

User roles

The access control system of the Remote firmware is based on three user roles.

These are tiered in a hierarchy.

User role

Description

Operator

The operator can switch between the displays of the connected

(standard user)

systems and operate these systems remotely. The operator has

access to the basic settings. He or she cannot make any

changes to the firmware.

Engineer

The production engineer can set up, parametrise and delete

remote connections. With the Pro licence, the engineer can add

existing applications in the firmware. He or she cannot access

the Windows user interface of the Thin Client.

The engineer can adjust the following settings:

• Displays

• User Interface

• Connections

• Keyboard Wedge

Admin

The administrator has full access authority to the Windows user

interface of the Thin Client. In addition to the options available to

the production engineer, the administrator can install third-party

applications and drivers on the Thin Client. He or she can

configure the network, make system settings via the Remote

HMI menu user interface and log into the regular Windows user

interface as Admin.

The following adjustments in the Settings can only be made by

the administrator:

• Maintenance

• System & Proxy

• Protection

• Access Control

• Import & Export

• Update

The Admin and Engineer user roles can be password-protected in the "Access

Control" menu.

When the firmware is started up for the first time, the user roles are de-activated and

the firmware starts with the Admin user role. Password protection is not active.

The Admin and Engineer user roles should only be given to staff familiar with Thin

Client administration.

2.6

Display resolutions

The Thin Client supports the display of non-native display resolutions for all types of

connection. Non-native resolutions are those where the video output of the server

does not correspond to the actual physical resolution of the Thin Client display.

Resolutions from 640x480 (VGA) up to 2560x2048 (QSXGA) can be selected. The

display and scaling behaviour varies according to the connection type.

The supported HMI platforms correctly display every regular server display resolution

from VGA to QSXGA. The aspect ratio is maintained with the maximum possible

display resolution. Thus, the Thin Client can continue to be operated via the

touchscreen even if there are black edges.

Remote HMI

Manual

Display of an RDP connection

As a standard, the video output of the server is started with the native resolution of the

Thin Client.

Display of a VNC connection

The video output of the server is displayed in the maximum possible size whilst

maintaining the correct aspect ratio. Hardware or software are used to scale to

achieve the maximum possible image quality.

Server resolutions higher than the native Thin Client display resolution are fully

displayed. If the server resolution strongly differs from the native Thin Client

resolution, the display of small structures may be restricted. Scaling may be adjusted

as required to use the Thin Client display fully. This might result in a distorted display.

Display of a KVM-over-IP connection

The video output of the server is fully displayed in the maximum possible size whilst

retaining the correct aspect ratio, provided the server resolution is equal to or less

than the native Thin Client display resolution. Non-native resolutions might result in

black horizontal and/or vertical edges.

For server resolutions greater than the native Thin Client display resolution the Thin

Client switches to panning mode. Here, only part of the server image output is visible.

This section can be moved when the cursor stops at a screen edge.

2.7

The virtual keyboard is automatically started when the Thin Client boots. The icon of

the virtual keyboard will appear at the top edge of the display.

During an active remote connection the icon of the virtual keyboard can be moved to

any position. The keyboard should then only cover less important parts of the

application. This position will be resumed whenever the remote connection is re-

established at some later date. The virtual keyboard does not have to be positioned

again.

Hotkeys

The Ctrl, Alt, Shift, Caps and Windows control keys on the touchscreen are used as

follows:

• Key has been touched, colour changes

• Key function has been executed, colour changes back
