Instruction "Config_Upload"
Explanation for the instruction "Config_upload"
Data type
SINT[10]
DINT
Default value Description
0 Data buffer for configuration data.
The real length of the data depends
on the complexity of the configuration
and the firmware version of the read-
er. With a standard configuration of
the RF680R/RF685R reader, we rec-
ommend a memory size of 4 KB. If
you use advanced reader configura-
tions (filtering) or want to change the
configuration in the future without
needing to adapt the memory size of
"IDENT_DATA", we recommend a
memory size of 8-16 KB.
Note:
When necessary, an array of any size
can be transferred to this parameter.
Note that the array must be ≥ 10 bytes
long (e.g. "SINT[12400]").
-- Version identifier (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 January
1, 1979, 00:00 (midnight). The identifi-
er is assigned when a configuration is
generated.
