The WIMS-Rio Sync Service is a Windows Service that syncs data and audit information to/from WIMS to/from Rio. 

The service runs on a scheduled basis every x number of minutes (see Configuring WIMS-Rio Sync Service).  With each run the service:

1. Retrieves all data for the last x days (Service, Days to Fetch setting), scans that data for changes (whether the data is entered, imported via an interface or calculated) in Rio since the last sync run and it's parameter is connected to WIMS (i.e. the Rio Parameter's description is set to Varid=xxx).  It will import that data with audit trail information to WIMS).

2. Finds data in WIMS that has changed (whether the data is entered, imported via an interface or calculated in WIMS) since the last Sync run and it's parameter is connected to WIMS (i.e. the Rio Parameter's description is set to Varid=xxx).  It will import that data with audit trail information to Rio.

3. Logs the number of data points synced to the Data Studio's Rio-WIMS Sync log.

WARNING: Care should be taken when syncing calculated data.  Sync WILL NOT sync data if the variable/parameter is calculated in both systems.  Therefore, a WIMS calculated variable should be synced to a Rio Parameter and a Rio Calculated Parameter should be synced to a WIMS parameter variable.

1. MLSS entered in Rio and Synced to WIMS. 

2. Total MLSS Mass calculated in WIMS and then synced to Rio.

3. MLVSS calculated in Rio and synced to WIMS.
