A datalog source is similar to a Communications Source, except the data comes from datalog files rather than from
RealTime communications. Whatever process is applied in the Data Value will be automatically applied to the datalog
result. Therefore, any data value that is based on the datalog source should use just a Pass-Through Data Process.
Properties
Name - The Name property makes the object easier for the RealEdit programmer to identify. Often it is a good idea
to use the same name for related objects, such as a Data Value that represents a Constant.
Data Value - The fundamental data unit for RealTime. A Data Value may be changed by a Data Process and can be
derived from any number of Data Sources.
Data Value Date/Time - The fundamental data unit for RealTime. A Data Value may be changed by a Data Process
and can be derived from any number of Data Sources.
Data Socket Sources
Data Socket Sources use the Component Works Data Socket control to access any OPC Server on the network and
query the server for information.

OPC URL - OPC URL is the OPC address of the Server and Parameter you will query. A browser is included in
RealEdit to help find the proper Server for your application:
Select the local host or browse Network Neighborhood to find the computer which is running the OPC Server and
select the parameter to assign to this Data Socket Source.
