Backing up a device configuration

You can back up the configuration of an S7-300/400 CPU in the TIA Portal. So you can download and test a new configuration to a device without any risk. If needed, you can restore the initial configuration of the CPU.

Requirement

  • The CPU has already been created in the project.

  • The CPU is online. If there is no online connection yet, an online connection is established during the backup.

Procedure

To create a backup of the current configuration of a CPU, follow these steps:

  1. Select the CPU in the project tree.

  2. Select the "Backup from online device" command in the "Online" menu.

Result:

A backup of the entire hardware configuration and software is created. The backup is stored in the project tree in the "Name of the CPU > Online backups" folder. The backup is assigned the name of the CPU with the time and date of the backup. You can rename the backup, but you cannot make any changes to the contents of the backup.
