How do I make operators see only the machines on their own line?

[SystemPulse]

We have 14 machines in two halls. Operators in Hall A complain that the dashboard and kiosk are cluttered with Hall B machines, and last week someone approved a downtime on the wrong machine because the names are similar (Press 03 and Press 03B).
I created the operator accounts on the Users page, but I didn't change anything except name and password. I see a Role field and something called Assigned Machines. What is the difference between the roles, and if I assign machines, will a supervisor still be able to see everything? I also want to be sure nobody on the shop floor can change tags or the project configuration.

You can solve both problems on the USERS page.
Roles
There are three roles: Operator, Manager and Developer.
- Operator: for shop-floor users. Works with the machines assigned to them: dashboard, work orders, downtimes and the kiosk.
- Manager: for supervisors and the production manager. Sees reports and the wider picture.
- Developer: for the one or two people who maintain the configuration (project, database connection, tags, machines). Writing a value to a PLC tag from Live > Tag is only available to this role.
Assigned Machines
Edit each operator with Edit User and select their machines in Assigned Machines. The hint on the form says it clearly: "A non-admin user can only see the machines selected here." After this, the Hall A operators will only see Hall A machines on the dashboard, Shift Monitoring and the kiosk, so the Press 03 / Press 03B mix-up can't happen.
If an operator opens the kiosk and sees "No active machine is assigned to you.", it means this list is empty for that user.
Recommended setup
- Operators: Operator role, only their own line's machines
- Shift supervisors and production manager: Manager
- Automation/maintenance engineer: Developer, limited to one or two people
- No shared accounts. Each operator signs in with their own account so the "Approved By" column in downtimes is meaningful. At shift change, the kiosk's Change user option makes the handover quick.
