Problem

Q: Whether Serial port/Ethernet pass-through and VPN pass-through can be used at the same time?

No. The device can use serial port/Ethernet pass-through or VPN pass-through, but cannot at the same time. 

Q: What are the differences between serial port/Ethernet pass-through and VPN pass-through?

Q: Can one V-NET account log in to multiple Clients?

Yes. Unlike a single account on the V-NET website, where one account can only log in from one end. The account can log in at multiple VPN clients, but the same PC can only log in to one VPN client.

Q: Can I log in to View account?

No. View Account is used only to view the device list.

Q: How to understand Remote LAN IP?

Remote LAN IP is the IP used by the PC to join the LAN of V-BOX/PLC and communication with the PLC and other devices, and it can be simply considered that the PC replaces the V-BOX in the PLC LAN.

Q: Does the PC pass-through affect normal network access?

• For the public network, such as Baidu, it can be accessed normally.
• For the local area network, it may be affectted. If the LAN of PC and the LAN of V-BOX/PLC iare in the same segment and the same IP, it may cause IP conflict.

Q: The exception occurs when two PCs on the same network segment pass through two V-BOXs on the same Intranet

There is a PC-A in the 192.168.42.X network segment at location A and a PC-B also in the 192.168.42.X network segment at location B. These two PCs each passthrough the same LAN BOX-A and BOX-B at location C.
Phenomenon: After successful passthrough, neither PC-A nor PC-B can access the devices on the intranet at location C or the access is intermittent, which is due to PC-A and PC-B have the same network segment, and the return packets from the intranet in C do not know whether they should be sent to A or B.
Solution: Two PCs in the same network segment should not passthrough at the same time, or modify the network segment of one of the PCs.

Q: How to manually install Virtual Network interface card (VNIC)?

• Confirm wvpn toll installed path. For example, the default path is C:\Program Files (x86)\Wecon\WVpn_PCclient.
• Confrim your windows system.for example windows10 64bits.
• Run "cmd.exe" as administrator.
• On the DOS command line, enter the directory where the script for creating the VNIC is located.

If the current computer is 32bit, enter in the DOS command line: 

If The current computer is 64bit, then enter in the DOS command line:

If "Drivers installed successfully." prompts, which means that the virtual NIC is installed successfully.

 Q: How to uninstall VNIC?

Open the "Control Panel "→" Network and Internet"→" Network Connection"→select "configuration" in the Ethernet properties  and uninstall the previous driver.

Q: The error when intalling Siemens software.

Open the "Control Panel "→" Network and Internet"→" Network Connection", select the network card (VPN network card) of type TAP-WINDOWS ADAPTER V9, right click on the properties, and do not select both the SIMATIC and PROFINET,  and then restart the computer.

Q: V-BOX only have one Ethernet port,new VPN can support？

Yes, only V-BOX online.Follow the VPN user manual to test

Q: If my V-BOX sell to customer side and do not want to configure V-BOX IP.V-BOX can connect with PLC by VPN?

User could use H series V-BOX.

If V-BOX is H series,H series can configure WAN IP(Means V-BOX IP with internet) and Lan IP(Lan IP connect with PLC),WAN IP use DHCP IP as below,customer’s router can arrange a DHCP IP to V-BOX.

LAN IP set a static IP,with the same segment with PLC.Then VPN software can set static IP to connect PLC.

✎Note: if WAN IP choose static IP,please set DNS,in order to connect V-BOX server.DNS is different in different country.It can be search from chrome.WAN IP segment must different with Lan IP segment.

such as Wan IP is 192.168.20.10, LAN IP is 192.168.1.12, In order to avoid network IP conflict

✎Note: if you want to use Lan IP,please set a WAN IP firstly

Q: VPN can support serial port pass-through?

VPN only can support Ethernet port pass-through. If user want to use series Port pass-through.please use the normal pass-through.

Q: Can WECON HMI download project by VPN tool?

Yes. But you have to use PI series HMI,and HMI+ system. HMI+ system is a new system which supports disconnection and reconnection internet function. So if internet is not stable, HMI project also can be download. But if normal PI HMI system, and there is a little interrupt to internet, the download is easy stop and can not reconnect.

Error 6003

Failed to connect the VPN server from V-Box side

These problems are mainly due to some unexpected situations on the device side.

V-BOX End

• Please make sure that V-BOX register time is correct. There are certain time requirements for VPN certification: If V-BOX time is much different from the server current time, WVPN pass-through will be failed. Click Update Time to make sure the device time is same to the server time.
• Please confirm that the V-Box network is connected and stable: Please pay attention to whether the V-Box's LAN has the restriction on the Network access. For example Firewall, Corporate intranet, etc. configured with filter rules.
• Please confirm whether to run the Lua script and whether the script takes too long time to run.
  • If the Lua script runs for more than 10 seconds at a time, it may affect the VPN penetration.
  • If it is set to execute the script every 1 second, and each execution takes about 500 milliseconds, there is no problem.
  • If it is set to execute the script every 1 second, but the execution exceeds 10 seconds due to an infinite loop or network request somewhere in the script, then VPN passthrough will cause VPN passthrough to fail.
• Please make sure the V-Box firmware version is updated to the date.

PC side

1. Open Control Panel →Network and Internet→Network Connect and see if a network card named TAP-Windows Adapter V9 exists. If not please try to install virtual network card (refer to the question 8).
2. Please ping the VPN server, if very delay,this error is possible to appear.

Error 6004

Failed to open start the local VPN

• Please refer to the Error 6003.
• Try to run the WVPN tool as administrator.

Error 6005

Incorrect VPN status

The V-Box to be pass-through is currently being pass-through by someone else. Because the VPN server resource need to preempt, if the V-Box is already pass-through by other client end, in this situation, the pass-through action will be failed at local PC. It need to wait for others to end the pass-through.

Error 6007

ASSIGN_IP for local VPN status error. 

• Please open the Windows command window as administrator.(Shortcut key is Win+R)
• Please enter the following two command into cmd.

• Restart PC

Error 6006~6017

Local VPN status error
This type of error is mainly due to the fact that the VPN program cannot connect to the VPN service normally due to the local network card, local network, software operating permissions, etc.
Please confirm whether the local network has intranet network restrictions.
If the intranet has restrictions on accessing public network services, the local VPN connection will fail, resulting in an incorrect state. For example, the IP of WECON server is prohibited from being accessed on the intranet, which may result in a constant connection (CONNECTING) state. Consult your network administrator or change the network.

Please confirm whether the local network is stable and the delay is low.
If the network where the machine is located has large fluctuations, for example, using a mobile phone to share the network with a computer may have large network fluctuations, which may cause always in RECONNECTING state. Please change the network.

Please confirm whether the VPN network card is installed normally.
If the VPN network card is not installed properly, it will also cause the local VPN status error. Please manually reinstall the VPN card according to the previous tutorial.

Please confirm the version of the VPN network card.
If other VPN software has been installed, the version of the VPN network card may not be compatible with the VPN network card used by the maintenance and control VPN tools, which will also cause local VPN status is wrong. Please refer to 6003 error to confirm the VPN NIC version.

Please confirm to run the PC-side tool with administrator privileges.
If the maintenance and control VPN tool is not run with administrator rights, the network card cannot be operated, and the local VPN status will be incorrect. Please run VPN tool as an administrator.

Please try restarting the computer.
Because the PC runs for a long time, after adding or deleting some software, it needs to restart to delete the remaining data or registry records. These data may be locked before restarting, which may affect the normal operation of the maintenance control VPN tool. If none of the above methods work, try restarting the computer.

Error 6018

Passthrough timeout
If the penetration fails for a long time, please confirm whether the local network or the device network is normal, stable and with low latency. Large network fluctuations can easily lead to VPN penetration reconnection and penetration timeout.
