Create Master-Slave

Instructions for use

Master-Slave is used to express a hierarchical relationship, for example, a light buoy can be regarded as a master object, and a top buoy, a flash, and a foghorn can be regarded as subordinate objects. A Master-Slave can only specify one master object, but can specify one or more slave objects, and the number of slave objects of the master object cannot be less than 1.

The following is a detailed description of the operation of creating a new Master-Slave by taking the example of adding a side buoy as a master object and a light as a slave object:

Operation steps

  1. With the Editable Chart Group open in Chart Data editing mode, on the Map tab, in the Relationship Management "group, click the Master-Slave button. The Master-slave Relationship Management "panel pops up.
    2. Figure: Master-slave Relationship Management
  2. Add the Master object of Master-Slave first, and then add the subordinate object of the Master object. There are two ways to add: Add from Select Objects and Add from dataset.
  3. Select the side buoy and other objects in the chart, and click the button on the main object toolbar to pop up the "Add the selected objects from map" dialog box. In the "Select object on map" list, select a side buoy object in the BOYLAT object Dataset, click the button to add the selected object on the left to the "Select Result" list on the right, and click the "OK" button. Add the object as the main object.

    Note: The "Select object on map" list only lists the objects specified in the S-57 standard that can be used as the main object, and only one main object can be added at a time, and multiple objects cannot be added.

  5. After adding the subordinate object of the master object, click the Apply button in the panel to complete the creation of the master-subordinate object relationship.

Precautions

The master-slave object that creates the master-slave object cannot already exist, and the specified slave object cannot be a slave object of another master-slave object, otherwise the creation will fail.
