The default shortcut is Alt + F8.

UNINTENDED EQUIPMENT OPERATION

Confirm that you have entered the correct device designation or device address in the “Communication Settings” dialog when downloading an application.
Confirm that machine guards and tags are in place such that any potential unintended machine operation will not result in personal injury or equipment damage.
Read and understand all user documentation of the software and related devices, as well as the documentation concerning equipment or machine operation.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

If there is an online user management (also refer to the chapter Users and Groups) established on the target device, at login you are prompted to enter the user name and password. For this purpose, the dialog box Device User Logon opens.

NOTE: If a password has expired, you are prompted to configure a new password.

NOTE: After several attempts to log in with incorrect credentials, your account may get locked for a time configured in the Change Runtime Password Policy dialog box.

NOTE: The layout of EcoStruxure Machine Expert views can change when you connect to the target device because the Online perspective is automatically selected when you switch to online mode.

NOTE: If the communication with the controller is encrypted or secured using user management functions, refer to the How to Manage Certificates on the Controller document for further information.

Selecting the View of the Communication Settings Tab in the Device Editor

Depending on the option selected for Communication page in the Tools > Options > Device editor dialog box, the Communication Settings tab of the device editor is displayed in three different modes. Refer to the description of the different tabs for details:

Mode	Communication page setting	Dialog of the device editor
1	Controller selection mode (default setting)	Communication Settings tab in controller selection mode
2	Simple mode	Communication Settings tab in simple mode
3	Classic mode	Communication Settings tab in classic mode

Login Procedure

The steps of the login procedure are identical. They only differ in the presentation of the Communication Settings tab.

For a successful login, the code generation must have been completed without detecting errors (refer to the chapter Build Process Before Login).

Step	Action
1	Execute the command Online > Login, or click the Login button from the toolbar, or press ALT + F8. Result: Since no target address has been set before, the Communication Settings tab of the device editor opens in the mode you selected. A message box is displayed indicating that a valid address has not been defined.
2	If only one controller has been detected by EcoStruxure Machine Expert, this controller is used as target device. If several controllers have been detected, double-click the controller you want to log in. NOTE: In controller selection mode and in classic mode, only those controllers are listed that have the same Target ID as the selected controller. To display all controllers in the list, set the Filter criterion to None.
3	Execute the command Online > Login, or click the Login button from the toolbar, or press ALT + F8. Result: A message box displays to inform you of potential hazards.
4	Click Cancel to abort the login operation or press ALT + F to confirm the message and to log in to the selected controller. Result: If you press ALT + F the connection to the controller is established, and you can download the application.
