Applies to:

PcVue version 8.10 SP1 onwards.
Summary:

This affects networked architectures using client – server archive units.
There was a change in what actions and events could be logged, from a station that is NOT the historical server, after version 8.10 SP1.
Although this is considered to be an enhancement there is the possibility of compatibility issues.
Details:

The following table illustrates the change in what can be logged from a station that is NOT the historical server after version 8.10 SP1.

 Action  8.10 SP1
  8.20 SP1 onwards
 Send program  No  Yes
 Alarm acknowledge  No  Yes
 Logon / Logoff  No  Yes
 Alarm mask  No  Yes
 Force variable (Var does not exist on historic server)  No  Yes*
 Force variable (Var exists on historic server)  Yes  Yes
 COS of logged bit NOT on historic server  No  Yes*

* Variable Name is NOT recorded. (Substituted with the variable Description in the Log Viewer.)
COS = Change Of State

In versions 10.0 Update 1, and 9.0 SP3, a compatibility flag was introduced to allow selection of either behavior. In these versions the compatibility flag has to be manually created in the file SvConf.dat in the project’s C folder. The format is:

[HIS\Compatibility\Units\ProprietaryFreeODBC\Log]
RecordOnlyLoadedVariablesAndLocalActions=1

In version 10.0 SP1 this compatibility flag can be set using an option in the Application Explorer Application Explorer.Project settings.Compatibility
