Table 10- 7 CodeTypesRWData
Root/Objects/DeviceSet/Read_point_x/RuntimeParameters/Com
monSettings/CodeTypesRWData
R/W
Definition of the data type for the "RWData" diagnostics variable
and the "ScanData" union used for "RWData" in the "RfidLastAc-
cessEvent".
The types "String", "ByteString" and "ScanDataEpc" are support-
ed. The type definition of "CodeTypesRWData" is "MultiStateDis-
creteType". This means that the variable has an "Enum" that
indicates the supported data types as "Property".
• 0: ByteString
• 1: String
• 2: ScanDataEpc
Table 10- 8 DeviceClock
Root/Objects/DeviceSet/Read_point_x/RuntimeParameters/Com
The internal device clock of the communication module
The communication module loses the time when it is switched
off. The time can be applied after switch-on by this variable via
Example:
10.2.5 RfidSettings
You can make the RFID settings on the communication module using these variables.
Table 10- 9 MinRssi
Root/Objects/DeviceSet/Read_point_x/RuntimeParameters/RfidS
ettings/Antennaxx/MinRssi
Lowest accepted RSSI value of an antenna
Transponders which are detected with a lower RSSI value are
counted as not detected. This is a value without a unit and with-
out direct reference to the power strength.
This variable is only supported by UHF readers.
