Passwords with PLCnext

iC9200 Series controllers are protected against unauthorized access and modifications with iCube Engineer by a controller password. To protect the controller configuration and operation mode, user roles with specified access rights can be defined for iC9200 Series controllers. The access data of the users who are authorized to access the controller and the user roles containing the permissions for the user are managed in the WBM (Web Based Management) of the controller. Here you add users, set the user password and assign the user roles. You can choose one or more user roles containing different permissions for each user. These permissions control the access to the controller.

The Safety PLC is protected by a controller password. The password protects the Safety PLC against unauthorized access. Writing data to the Safety PLC (for example, writing the project to the controller or modifying any controller parameters), switching the operation mode or executing debug commands is only possible once you have entered the Safety PLC password in iCube Engineer. When logged off from the Safety PLC, the safety-related data can only be read from the controller and displayed but not debugged in the online editors.

The project password protects the safety-related logic in the iCube Engineer project with a safety-related controller against unauthorized modifications. The project password is required when you want to edit (create, modify, or delete) safety-related devices in the PLANT, the COMPONENTS area and safety-related POUs. Safety-related parts of the project can only be edited while being logged on to the Safety-related Area which is an area of responsibility restricted to authorized members. When logged off, safety-related data are displayed in read-only mode.

The project password must be created when you insert a Safety PLC into an empty project.
