Config_Upload/-_Download
Using the "Config_Upload" and "Config_Download" blocks, you can read ("Config_Upload")
or write ("Config_Download") the configuration of the RF680R/RF685R readers via the
control program. This block enables the configurations of the readers connected to this
controller to be read and written.
The configuration data is not interpretable data. Save the data on the controller so that it can
be written to the reader again if a device is replaced. Bytes 6-9 (see table below) contain a
configuration ID with a unique version identifier. With the configuration ID, when performing a
"Config_Upload", you can check whether the configuration data read matches the
configuration data stored on the controller. The configuration data has the following
structure:
Table 8- 7
Structure of the configuration data
Byte
Name
0
Structure identifier (2 bytes)
2
Length information (4 bytes)
Length of the version identifier and parameter block
6
Version ID (≙ CONFIG_ID; 4 bytes)
Based on the identifier, you can uniquely identify the configuration.
This is a time stamp in Linux format.
The time stamp indicates how many seconds have passed since Jan-
uary 1, 1979, 00:00 (midnight). The identifier is assigned when a con-
figuration is generated.

Parameter block
"Config_Upload/Config_Download" can be executed on every channel of the
RF680R/RF685R. It is always the same configuration data that is transferred.
