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".
