Operation Instruction of VNC function on

Kinco HMIware

Remote access and control via VNC function has been added in the latest Kincoware version. By the VNC function,

users could access and control their desktop applications wherever they are in the world.

VNC system is composed of client-side, server-side and protocol. The server side shares screen with client-side,

while the client-side interacts with server side by monitoring and controlling server-side.

VNC is OS independent. Users could use the VNC system to remote control HMI via PC, mobile and so on.

Various client-sides

Kinco does not provide the VNC software. Users could download from the internet:

VNC software for PC: VNC Viewer

Browser: IE, F irefox…

VNC software for mobile terminal: most mobile system support VNC software, for example: VNC/RDP.

1. JAVA plugin tool is required by browser access. Generally, PC has the JAVA

plugin. Please refer to Java.com to install if there is no JAVA plugin on PC.2.

You can open multiple VNC Viewer clients to access to multiple HMI at the

same time.

Access via LAN

Remote control HMI by PC via LAN

【Example 1】Remote control MT4414TE by PC. MT4414TE works as server, while PC as client.

1.

Only the HMI models with Ethernet port support VNC function for the VNC

function is realized via Ethernet.

1) Tools required for Client-side:

2) The related system registers of HMI are as follows:

Register Function

LB9290 Open VNC function. Set to “1” to open the VNC function.

LB9291 Mask user operation. Set to “1” to mask user operation(check only,

cannot operate)

LB9292 Operation password enabled. Set to “1” to enable operation password.

LB9293 Inquiry password enabled. Set to “1” to enable inquiry password.

LW10146~LW10147 Operation password

LW10148~LW10149 Inquiry password

3) Parameter settings for HMI:

Set IP of HMI as follows:

1. Take the default gateway in LAN.

Set the VNC related registers:






Kinco


4) Parameter setting on PC

Input IP of the target HMI:

Input Password (Operation password or inquiry password)

Monitoring on PC:






Kinco


Changes on HMI is displayed on PC simultaneously, meanwhile, user could control HMI by operating on PC.

1. If input inquiry password on PC side, then users only could check HMI

information, but cannot operate.

2.

If input operation password on PC side, then users could check HMI

information and operate HMI on PC, but cannot operate.

3.

If there is no password set on HMI, then no passwords required for

monitoring or operating HMI.

Remote control HMI by mobile via LAN

【Example 2】Remote control MT4414TE by an android mobile. MT4414TE works as server, while the

android mobile as client.

1) Tools required for mobile

2) Parameter setting of HMI is the same with 【Example 1】

3)

Parameter setting on mobile






Kinco


1.

Input IP in the Address box.

2. The default port is 5900, please do not change it, otherwise, may not get

connection.

3.

Nickname and User name can be omitted.4. Input operation password or inquiry password.

Monitoring on mobile:

mobile.

Remote control HMI by browser via LAN

【Example 3】Remote control MT4414TE by browser.

1)

Parameter setting of HMI is the same with 【Example 1】

2)

Open the browser, input IP and port of the target HMI in the website box: http://192.168.130.8:5800

Input password (Operation password or inquiry password)

Monitoring by browser:



http://192.168.130.8:5800/

http://192.168.130.8:5800/

http://192.168.130.8:5800/

Changes on HMI is displayed by browser simultaneously, meanwhile, users could control HMI by operating on

browser.

1.

The remote control by browser is realized by a JAVA plugin running on the

website. Please make sure that JAVA software has been installed on PC.

2. Default port for browser access is 5800. Please do not change it, otherwise

may not get connection.

3. Only after updated kernel and Rootfs by this version software or above, the

HMI can support the remote control by browser.

Access via WANFor remote access via WAN, users need to set port mapping of HMI by router.

For remote access by VNC Viewer on PC via WAN, users need to map IP of target HMI to port number 5900.

【Example 4】The IP of the remote HMI is: 192.168.4.39






Kinco


1) Port mapping:Choose menu“Forwarding->Virtual Servers”,click the Add New…button

2) Parameter setting of HMI:

3)

Assumed that the WAN IP of the local network where the HMI located is 192.168.100.14, then, users

need to input IP 192.168.100.14 into VNC Viewer and mobiles of external network to remote control

HMI. Choose menu ”Network->WAN”

For remote access by browser via WAN, users need to map the HMI IP to port number 5800.

【Example 5】 The IP of the remote HMI is: 192.168.4.39

1.

Port mapping: Choose menu“Forwarding->Virtual Servers”,click the Add New…button






Kinco


2.

Parameter setting of HMI is the same with 【Example 4】

3.

Assumed that the WAN IP of the local network where the HMI located is 192.168.100.14, then, use the

browser of the external network to visit website: http://192.168.100.14:5800 to remote control HMI.

1.

The Gateway must been set in the same network segment for access via WAN.

2.

The firewall and antivirus software are suggested to be closed, for it may affect

the VNC function.

Simple router mapping method: If the DMZ host is opened on PC, then users could remote control HMI by

VNC without port mapping.

【Example 6】 The IP of the remote HMI is: 192.168.4.39

1)

Router mapping：Choose menu ”Forwarding->DMZ”

2) Parameter setting of HMI is the same with 【Example 4】

3)

Assumed that the WAN IP of the local network where the HMI located is 192.168.100.14, then，users

need to input IP 192.168.100.14 into PCs of external network to remote control HMI.

If users need to access multiple HMIs by VNC via WAN, then the router is required for supporting port

self-definition of external network port. The model TL-WR841N (TP-LINK) supports port self-definition of

external network.

【Example 7】IP of remote HMI1 is 192.168.100.35， IP of remote HMI2 is 192.168.100.36.

1)

Port setting of router: add two new items in [transfer rule]-[Virtual server]

1. For access by VNC Viewer, the internal port must be set to 5900 by router, and

serve port can be set as casual value. Input IP and internal port for access by

VNC Viewer via WAN.

2.

For access by browser, the internal port must be set to 5800 by router, and

serve port can be set as casual value. Input IP and internal port for access by

browser via WAN.

2)

Parameter setting of HMI:

HMI1:

HMI2:






Kinco


3) Assumed that the WAN IP of the local network where the HMI located is 203.110.174.214, then, users

need to input 203.110.174.214:5900 and 203.110.174.214:5901 into PCs and mobiles of external

network to remote control HMI.

1.

The firewall and antivirus software are suggested to be closed, for it may affect

the VNC function.
