Communication by OPC server
server B&R is a part of the software package Automation NET/PVI
The software Automation NET/PVI can detect whether it is launched and running on a PC manufactured by the B&R
- If the software Automation NET/PVI is installed and running on the computer manufactured directly by the B&R company, then it does not need any runtime licence to work.
- If the software Automation NET/PVI is installed and running on the computer manufactured by another company than B&R, then the runtime licence is necessary.
The runtime licence key can be burchased in the form of USB, LPT or DLL library.
- USB and LPT keys allow running the software Automation NET/PVI on a single PC.
- DLL library allows running the software Automation NET/PVI on unlimited numer of computers. This solution is suitable for large corporations/enterprises with corresponding pricetag of approx. 30 000 EUR.
Without the runtime licence, the software runs for two hours in trial mode. After this period the application stops. The communication can be reactivated (for another two hours) by restarting the PVI Manageru (main PVI component).
OPC server setting:
Basic settings of the server is contained in the INI file named "BR.OPC.Server.ini
" that is located in the installation folder B&R
in subfolder PVI/Vx.xx.xx/Bin.
This file contains entries regarding the locations of files with variable definitions (in the ConfigPath
section) and also the definitions of configuration files to be used by the OPC
server (in the ConfigFiles
section). The OPC server
configuration files are in XML
format with the extension *.opcs
Then the PROMOTIC application will communicate as a client by the OPC interface
The usage of the PmaOpcDaClient
object requires purchase of the "PmOPC" licence
. When developing the application in the freeware mode PmFree
, or with development environment
and while testing it in runtime, this component is always functional.
