Config_Upload/-_Download

Using the "Config_Upload" and "Config_Download" blocks, you can read ("Config_Upload")
or write ("Config_Download") the configuration of the RF61xR/RF68xR readers and of the
RF18xC communications modules connected to this controller.
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. When multiple readers has the same
configuration, you only have to save the configuration data once per reader type. A single
backup can be copied to all identically configured readers during the download.
Bytes 6-9 (see table below) contain a configuration ID (CONFIG_ID) with a unique version
identifier. With the configuration ID, when performing a "Config_Upload" on the RF18xC, you
can check whether the configuration data read matches the configuration data stored on the
controller. You can also use the device status to check the serial number to see if the device
has been replaced.
The configuration data has the following structure:
Table 3- 8
Byte
0
2
6
10 ... end "DATA"
"Config_Upload/Config_Download" can be executed on every channel of the
RF61xR/RF68xR. It is always the same configuration data that is transferred. The
configuration data of the RF18xC communications module can be transferred exclusively via
the "CM configuration_1" module.

Structure of the configuration data
Name
Structure identifier (2 bytes)
Length information (4 bytes)
Length of the version identifier and parameter block
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.
