Aktuelle Version 2.1
Der PC OPs Server verwendet das OPC Standard-Interface, um OPC-kompatible Grafikpaketen den Zugriff auf Daten vom LoggerNet Server zu ermöglichen. Über eine einfache Browser-Oberfläche können Sie die Daten zur Anzeige auswählen. Außerdem kann man sich Input Locations, Final Storage Daten und Statistik zur LoggerNet Server Kommunikation anzeigen lassen oder Kontrollen ausführen.Lesen Sie mehr
The PC-OPC Server uses a simple browse interface that:
A PC-OPC trial version is available, at no charge, from our downloads page. The trial version generates random data instead of retrieving the data.
|Operating System||Windows 7, Vista, 2000, or XP|

|Requirement||Licensed copy of LoggerNet or LoggerNetAdmin must be running on the same PC or a remote PC that is accessible via TCP/IP.|
Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
Requires a licensed copy of LoggerNet running on the same PC or a remote PC that is accessible via TCP/IP.
Many software and hardware products support OPC. Products that have been tested by Campbell Scientific include Iconics Genesis, Intellution IFIX, and National Instruments Lookout. PC-OPC supports Data Access Standard 2.05a only.
Minimum recommended hardware is 300 MHz Pentium II processor with 128 Mbyte of RAM and screen resolution of 800 x 600. Recommended computer operating systems are Windows Vista, 2000, and XP.

The PC-OPC Server works with OPC Data Access Specification 2.05a.
The PC-OPC Server demo enables users to verify if an OPC client will work with Campbell Scientific’s OPC server. The trial version doesn't actually connect to a LoggerNet server or provide any true data. It only provides mock data.
If the OPC client software supports getting data from an SQL server, LoggerNet Database Software (LNDB) may be a more appropriate option than PC-OPC. LNDB stores a complete history of data tables retrieved from the data loggers in an SQL server. In contrast, PC-OPC only provides the last record from each data table in the LoggerNet cache when it is first started and any new records that are collected by LoggerNet while the PC-OPC Server is running. If the OPC client is storing PC-OPC data in its own database, gaps will be created (missing data) in the OPC client database if the PC-OPC Server, the OPC client, or both are not running when LoggerNet collects the data.
The blog article "How to Navigate the World of Software Upgrades, Patches, and Trials" explains the difference between patches (free of charge) and upgrades (for a fee). This example quickly shows the difference between an upgrade and a patch:
Major version change, such as 1.3 to 2.0
Minor version change, such as 1.3 to 1.4
Typically requires purchase for a fee

Campbell Scientific dataloggers cannot communicate directly with LabVIEW. However, after retrieving data collected by any of the Campbell Scientific dataloggers and placing the data in the LoggerNet data cache, the data can be shared with LabVIEW using a LoggerNet client called PC-OPC. A trial version of PC-OPC is available in the Downloads section of the PC-OPC product page.
The PC-OPC Server software provides a standard interface that allows third-party OPC-compatible graphics packages, including LabVIEW, to display the datalogger data.
In addition to using the PC-OPC Server and the data socket feature in LabVIEW, communication can also be established using LoggerNet-SDK with ActiveX controls.
