Description of the |
|---|---|
|
|
The data transfer to the communication component is triggered in the variable server directly after write access to a structure/field element (default setting). |
|
|
The data transfer to the communication component is only triggered in the variable server after the data transfer for the entire field has been triggered. This is possible, for example, if the process variable is in a group that explicitly sends the write request to the communication component via a trigger (see also Trigger variable parameter). example: Deactivating the Individually writable option is necessary, for example, if the members of a structure are linked to input elements in a configuration dialogue and are only to be transferred to the controller together after the dialogue has been confirmed by the user. |
