Configure advanced replication settings

If you notice issues with the default replication configuration, you can adjust it in the Settings window.

To configure replication settings:

1. Select Settings in the sidebar. The Settings window opens to the Replication tab.
   

2. Adjust one or more of the following replication settings:

   • Data source name: The default data source name is the local computer name.It is used to organize entries on the CONNECT data services site hierarchically. You can change this name here if necessary.

   • Min SF duration (seconds): This represents the minimum duration in seconds that the replication service functions in store-and-forward mode, even if the condition that triggered this function no longer exists. The duration can be an integer from 0 to 3600. Pick a value that provides a smooth transition for store-and-forward operation and prevents the system from repeatedly going in and out of store-and-forward mode.

   • Min disk free space for SF (MB): This lets you adjust how many MB are reserved for store-and-forward data. The default is 125MB but you can increase this if necessary.

   • HCAL SF buffer count: Specifies the number of 64 KB memory buffers allocated to the replication server. You can set the buffer count between 128 and 2,048. The default value is 128 and is usually sufficient. This value generally needs to be higher if you configure many tags or if data rates are high. If enough buffers get marked as full, the system switches to store-and-forward mode and writes data to disk.

   • CONNECT SF buffer size (MB): This refers to the size of each buffer used by the HCAL layer to buffer data in case there is a bottleneck and data can't be sent as quickly as it's received. About half of this buffer is assigned to the StoreForward size, and half to the MaxBufferSize setting in the agent. You may need to increase the buffer size to accommodate high data rates.You can type an integer from 20MB to 2048MB.

   • Interpolation type real: For tags that define their data source as real data, this setting determines if CONNECT will plot trends using Linear or StairStep interpolation. The default is Linear but you can change it to StairStep if desired.

   • Interpolation type integer: For tags that define their data source as integer data, this setting determines if CONNECT will plot trends using Linear or StairStep interpolation. The default is StairStep but you can change it to Linear if desired.

Important: If you leave this page before saving, the Configurator will not remember your changes.
