Issue
Use L-IP and NL220 to compose Vista LNS database. How to move the database from the engineering PC to the site PC?
Environment
- Vista 5.X.X
- LNS Network
- NL220
- Loytec L-IP
Cause
Due to the complexity of LNS network, it is recommended to follow the steps listed below to move the LNS database and Vista database from an engineering PC to a site PC. Otherwise, it may result controllers offline, Vista database opens extremely slow or freeze.
Resolution
NL220+L-IP is the most common combination for LNS network. How to move the database completed on the engineering PC to the site PC? The following steps can be followed:
-
The software needed to be installed on site PC: Vista Server, Vista ToolPack, NL220.
-
A NL220 dongle is needed. (The dongle does not need to be locked to the site PC for moving database purpose; however, it is recommended to have the dongle locked to the site PC for future maintenance purpose.)
-
Backup the LNS database on the engineering PC. (Select “Backup Project” in the NL220.)
-
Make a copy of Vista database.
-
Copy both backups (LNS and Vista) onto the site PC.
NOTE: It is recommended to keep the paths of both databases the same. Otherwise, it may results graphic pages lost.
-
Specify the folder path of Vista Server on site PC to the backup database.
-
Add the L-IP interface in the Control Panel.
-
Plug the NL220 dongle onto the site PC. Open NL220, create a new project and select the interface as L-IP.
-
Close the project, select “Restore Project” and specify it to the backup database for NL220.
-
Open the NL220 project again and select the System Plug-in.
-
Update the LNS database to Vista Server in the System plug-in again.
-
Select the “Commence Communication” to start the communication.
-
Open TAC Vista Workstation. Then the LNS interface in the Workstation should be online.
NOTE: without a NL220 dongle plugged in the site PC, TAC Vista workstation should operate normally. However, it is impossible to make any change to the LNS database.
