PC-OPC OPC Server (Single License)


Current Version: 2.1

The PC OPC Server uses the OPC standard interface to allow third-party, OPC-compatible graphics packages to view data from the LoggerNet server. This software provides a simple browser interface that allows you to easily select the values you want to display. It also allows you to view input locations, final storage data, and LoggerNet communications server statistics, as well as perform control operations.

Benefits and Features


Technical Description

The PC-OPC Server uses a simple browse interface that:

  • Provides data via “data tags” to any SCADA or third-party software that supports OPC
  • Updates, or pushes, data to third-party software as the LoggerNet server collects it from the datalogger(s)
  • Allows third-party software to set input locations, variables, ports, and flags in our dataloggers

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.

Expand AllCollapse All

  1. 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.

  2. The PC-OPC Server works with OPC Data Access Specification 2.05a.

  3. 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.

  4. 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:

    Upgrade 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

    Free of charge

  5. Campbell Scientific data loggers cannot communicate directly with LabVIEW. However, after retrieving data collected by any of the Campbell Scientific data loggers 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 data logger 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.
