Introduction
In order to create access rights of certain ctrlX Data Layer nodes for specific users, there is a node called scope in "datalayer/security". By configuring this node we can assign special access to the defined users.
Overview ctrlX Data Layer scopesIn this How-to article I will guide you through a step-by-step description of how to configure this feature. Further description is available here.
Prerequisites
ctrlX CORE
ctrlX WORKS to install ctrlX CORE virtual
Configuration
Step 1: Define the scope
Go to the Data Layer and navigate to datalayer/security/scopes and click on Create:
Navigate to scopes in ctrlX Data LayerInsert the user-defined scope, t.e.
{ "identifier": "datalayer.MotionOnly", "name": "Motion/Nodes/Only", "description": "specific datalayer rights definition -> motion", "permissionsR": ["motion/**"] }
And click on Create:
Insert the user-defined scope
A scope contains the following permission lists:
permissionR:
List of addresses that may be accessed for reading, browsing, and reading metadata.
permissionRW:
List of addresses that may be accessed for reading, writing, browsing, and reading metadata.
permissionX:
List of addresses that may be accessed for creating, deleting, browsing, and reading metadata.
permissionRWX:
List of addresses that may be accessed for creating, deleting, reading, writing, browsing, and reading metadata.
An address in one of the lists may contain placeholders:
*:
Stands for any node
Can be used as the part between two "/" or at the end
**:
Stands for any node trees
Can be used at the end
Examples:
datalayer/nodes:
Allows to access the node "datalayer/nodes"
motion/**:
Allows to access all nodes below motion
devices/drives/**:
Allows to access all nodes below "devices/derives"
motion/axs/*/pos:
Allows to access all "pos" nodes of all axes
Step 2: Change the permissions of a user
To change permission for a specific user go to "Settings>Users & Permissions>Users" as shown in the picture below and click on the pencil-like icon "edit" for chosen user.
Navigate to change permissions for a userNow on the newly opened page, navigate to the individual permissions tab and scroll down to "Data Layer scopes" as shown in the picture below.
Set permission Choose the defined permission and click on save.
Now from the next login of that user, changes will be applied and it will look something like the below image 🙂 .
