Setting a write permission for a single instance

This how-to guide uses the equipment types from Example equipment model.

Initially, History is configured so that everyone can see everything but only users in RTDB-admin group are able to write or modify anything.

1. Open Engineering UI. Locally on the server the Engineering UI can be accessed by navigating on a web browser to https\://localhost/history.

2. To see the ACL permissions for an object, right-click the object on the UI and select Security. Easiest way to open a data browser is from the cube symbol by the user settings as shown in the image below.

   

3. After opening the below menu by right-clicking an instance, we choose security and this opens the following permission settings.

4. We want to give the user Operator access to write to this pump instance's properties. You must be logged in with an admin user to modify ACL entries.
   1. In the Account field at the bottom, Type \Operator .
   2. Then click Add New Row.
   3. On the new ACL row, toggle on the checkbox to allow writing. Pen icon indicates writing access.
   4. Press OK.

5. Now Operator user is able to write to this pump instance's properties, but has no access to other instances we don't want.
