CP-Link 3

CP-Link 3 | Ethernet- and IP protocol-based desktop

transfer software

CP-Link 3 transfers the desktop of a PC via

Ethernet to several Panel PCs and the opera-

tor mouse and keyboard entries to the host

PC. The screen contents are captured by a

virtual graphic adapter in the host PC and

sent using Ethernet to one or more Panel PCs

with Windows operating systems (CE, XP,

Windows 7 or Embedded Standard). Net-

working can be done using cost-effective

standard Ethernet cables (CAT 5) which are

suitable for drag chains.

Since the data and image transfer are

based on TCP/IP, the operating and display

functions can be extended using the Internet.

Panel PCs can be integrated using the Inter-

net via VPN (Virtual Private Network). A VPN

service must be available for the Internet

security functions.

Keyboard entries, touch screen and

special key functions are transferred from

the client to the host PC via Virtual USB.

USB devices connected to a Panel PC appear

in the host PC like locally plugged-in devices

and can be used in the normal way.

Virtual USB emulates a USB root hub in

the host PC. If a USB device is plugged into

a Panel PC, then the virtual hub logs the

device on to the operating system of the

host PC and transparently transmits the

ensuing communication. For the operating

system, the USB device behaves as though

it was directly connected to the PC. Virtual

USB transfers the standards USB 1.1 and

USB 2.0. As communication takes place using

100 Mbit/s Ethernet, the USB 2.0 transmis-

sion performance (480 Mbit/s) is restricted.

Additional input/output devices on the

Panel PCs, such as rotary switches, buttons,

etc., are read in by the host PC using an addi-

tional communication channel. Printers and

webcams, which are connected to a Panel

PC by means of USB, can be used from the

host PC.

The scope of delivery for CP-Link 3

includes host and client software. The host

PC may have Windows XP, Windows 7 or

Embedded Standard installed. Panel PCs with

Windows CE, Windows XP, Windows 7 or

Embedded Standard are used as clients. As

the application software (PLC/NC, HMI, etc.),

once started, runs on the host PC, any neces-

sary software licences are only payable once

for the host PC. The client Panel PCs only

receive image data. Apart from the operat-

ing system and CP-Link 3, no other software

licence is required for the clients. Even for

PCs with more than one graphics card only

one license per application software is

required.

The CP-Link 3 software is available in

three versions:

– Single Desktop

– Multi Desktop

– Extended Desktop
