These alternative methods are described below.
Table 10- 9 Properties and requirements for the backup options
Backup options Properties
Backup on the controller
• Module replacement possible without PG
•
Automatic sequence possible
⇒ The automatic sequence needs to be programmed by the user.
Backup in the STEP 7 project
•
Download to the communication module only possible manually
via STEP 7
• No management of configuration versions
⇒ Only the last version is ever stored (no storage of older ver-
sions).
⇒ You need to update the configuration version in the project
yourself manually.
Backup as an *.xml file on the
PC
•
Configuration data is saved regardless of the project and control-
ler
⇒ The download to the communication module can be performed
manually using the WBM user application.
• You can copy additional communication modules of the same
type
•
Older configuration versions can be saved (versioning)
⇒ The updating and versioning of the configuration versions
needs to be started and managed manually by you yourself.
Backup on the controller
Using the "Config_Upload" and "Config_Download" blocks, you can read ("Config_Upload")
or write ("Config_Download") the configuration of the communication module
("CM_Configuration_1") via the control program. Since the configuration is stored
permanently, you need to reserve a data block for this on the controller.
To ensure that the communication module was replaced correctly, you can read out the
version ID (CONFIG_ID) of the communication module and compare this to the Config ID
that was stored earlier in the controller with the "Config_Upload" command in the data block.
You can also use the device status to check the serial number to see if the device has been
replaced.
You can find additional information on programming the blocks and the structure of the
configuration data in the section "Config_Upload/Download" of the manual "Ident Profile and
Ident Blocks, Standard function for Ident systems".
