Value Synchronization Service

The role of the value synchronization service  (ValueSyncService ) is to allow a tag to register a list of named variables to be kept in sync. The following VTS tags use this service: 

•      TotalizerTag

•      CounterTag

•      SelectorSwitch

 At this time, this service is meaningful only for tags. This service is an alternative to the NetworkValues service which at times can be undesirable for speed, memory and synchronization reasons.  NetworkValues do not allow you to control the RPC frequency or when to write to disk. ValueSynService does.
