vrnode/sync

Enable or disable synchronization of fields with client

Syntax

sync(vrnode_object, 'field_name', 'action')

Arguments

vrnode_object	Name of a vrnode object representing the node.
field_name	Name of the field to be synchronized.
action	The action parameter determines what should be done: 'on' enables synchronization of this field. 'off' disables synchronization of this field.

Description

The sync method controls whether the value of a field is synchronized.

If you set the field to be synchronized to 'on', the field value is updated every time it is changed on the client computer. If you set the field to 'off', the host computer ignores the changes on the client computer.

Synchronized fields add more traffic to the network line because the value of the field must be resent by the client any time it is changed. Because of this, mark for synchronization only the fields you need to scan for changes made on clients (typically sensors). By default, fields are not synchronized and their values reflect only settings from MATLAB^® or the Simulink^® software.

Note

Synchronization is meaningful only for readable fields. Readable fields are of data class eventOut and exposedField. You cannot enable synchronization for eventIn or nonexposed fields.
