Backup options
Backup on the controller
Backup via the WBM (as *.xml
file)
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/a variable for this in the controller.
To ensure that the communications module was replaced correctly, you can read out the
version ID (CONFIG_ID) of the communications module and compare this to the Config ID
that was stored earlier in the controller with the "Config_Upload" command in the data
block/in the variable. 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".
Backup via the WBM
On the upper toolbar of the WBM, there are two buttons for loading and saving
configurations. These buttons enable you to save configurations, reload them and transfer
them to other communication modules. You will find further information on saving and
loading the configuration on or from the PC in the section "The WBM (Page 60)".
