Basic Settings
|

▪Application Name Specifies the application name for the
DDE interface.
▪The period for notifying the client of value changes Specifies the frequency at which value change notifications are sent to the
DDE client.
▪Add a period after the topic name
For this setting, please refer to "Use as DDE Server".
▪When a value is requested (REQUEST), it is read from the cache. In the case of
Excel, a read request (REQUEST) is sent for each tag at startup, so checking this item to read from the cache value will speed up startup. However, when using the DDERequest function from VBA, an error will occur if there is no cache value. In that case, create Static tag and check "Start automatic monitoring" in the folder settings to have a server cache on the server side, so the cache will be updated automatically.
