CSIOPCServer

• The specified data tag does not exist in the datalogger table (because an

error was typed when entering the data tag directly, a new program was
downloaded to the datalogger, or the data tag was removed from the
datalogger program).

• The table for a specified data tag does not exist or is not being collected by

the LoggerNet communications server.

• The LoggerNet communication server has entered a Secondary Retry state

with the datalogger because of communication failure with the device.

• The data value retrieved from the datalogger is out of range and is

returned as NaN (not a number).

In instances where the data tag existed but has been removed from the program
or from collection, once the situation is resolved collection of that value will
resume automatically. If the Bad data quality is due to communication with the
datalogger being in a secondary retry state, the display of good data values will
resume when LoggerNet restores normal communication with the datalogger.

6. Technical Notes

6.1 Registering the CSIOPCServer

If the CSIOPCServer executable is moved to a different directory or if that
directory is renamed, it will be necessary to re-register the server for it to run
automatically when an OPC client is started. Open a command prompt screen
and change to the directory in which the executable resides. Then type:

CSIOPCServer

/RegServer

In some instances, you may wish to remove the CSIOPCServer application as a
COM server from your computer. Open a command prompt and change to the
directory in which the executable resides. Then type:

CSIOPCServer

/UnregServer

6.2 DCOM

CSIOPCServer has not been tested for DCOM compatibility. Therefore,
DCOM implementation is not supported by Campbell Scientific. We do not
support running the CSIOPCServer on one DC to feed ODC clients on other
PCs.

6.3 Server and Device Operational Statistics

The server controller and individual devices maintain statistics that help to
describe their operation. These statistics are made available to the clients in a
collection of tables associated with a virtual device. It is represented by
_ _statistics_ _ in the communications server.
