General Information :

This page describe the installation details for all kinds of OPC servers.The OPC servers are located at S:/OPCServer.

Generic Tools :

  • Server Explorer x.x.x is a generic OPC client for debugging.
  • Once you installed the Server Explorer, you can open the dialog to get a list of available OPC server on both local and remote machines. (default installation path C:\Program files\National Instrument\shared\Server Explorer)

  • You can see many OPC server in the list. (OPC20CanOpen+ for Elmbs, WienerKVASER.OPC_SERVER for CAN wiener fan trays, and WIENER.Plein.Baus.OPC.Server.DA.1 for Marathon channels)

  • selete the OPC server you want to connect to, and click "Connect", you will see the following dialog.
  • Enter an bigger value in the "update rate" textfield (normally several seconds, e.g. 5000), otherwise the OPC server may be too hurry to dead.

  • now, you are able to get all the OPC items in this OPC server. The "Quality" stands for the OPC connectivity. "good" means connected and working fine, and "bad" means the connection is lost.

  • You can even operate on the OPC items. Right-click at the item, you will see these property dialogs, you can read/write the value of the OPC items.


  • Extract CAENOPC/
  • Install CAENHVOPCServer_x.xx/setup.exe, select default option
  • Install OPCServerConf_x.x.x/setup.exe, select default option
  • Run Program/CAEN/HP OPC Server Configurator to add entry for specific module


  • Extract ELMB/ and install setup.exe (for kvaser interface)
  • Generate config file using fwElmb component and overwrite CANopenOPC/OPCCanServer.cfg

Wiener Fan tray:

  • Extract WienerFanTray/WienerOPC_xxxx_release to somewhere.
  • In the dest directory, run WienerOPC_KVASER.exe /RegServer to register the OPC server
  • You can run Wiener_Config.exe to define a config for Wiener Fan trays then. Or you can export config file from PVSS fwWiener component.

Wiener Maraton(Ethernet):

  • You have to install WienerMaraton/net-snmp first. Some times, the net-snmp will replace the %PATH%, so it is recommended that you backup the %PATH% first.
  • You can check the functions of net-snmap with snmpget -v 2c -c public xx.xx.xx.xx sysUpTime.0 to test the connectivity bwtween this machine and the Wiener Maraton Power Supply, where xx.xx.xx.xx is the IP address of Maraton.
C:\Documents and Settings\kzhuo>snmpget -v 2c -c public sysUpTime.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (7563501) 21:00:35.01
C:\Documents and Settings\kzhuo>snmpget -v 2c -c public sysUpTime.0
Timeout: No Response from
  • Then install WienerOPCS-x.x.x.xx , and uncheck something like "auto-register OPC server", because there are some bugs.
  • Enter the installed path, normally C:/Program Files/W-IE-NE-R/WienerOPCS, and run WienerOPCS.exe /RegServer to register OPC server.
  • Then you can generate your own config file for Maraton:)
