Parameters

 

Setting Value

 

Type:

Boolean

 

False –Finished. True–start.

 

If you set the CtlUpdate property to True, the value will be retrieved from the server periodically and the client cache will be updated.

The update period is specified in the NetworkParam property.

Retrieving values from the client cache is fast. To retrieve a value from the cache, use the RealVal/ReadVals method and specify "0-client-cache-value" for the DataSouce argument.

When a value changes due to automatic updating, an event such as ValueChanged will occur.

Please note that automatic updates only occur for active tags.
