At the input of the RFID function block, this structure provides the possibility to transfer an arbitrary configuration to the RFID reader.
The RFID reader configuration last read is specified at the output with the structure ST_RFID_Config. Supplementary information about configurations can be found in its description.
Configuration data can be available in the form of a specific configuration structure (ST_RFID_CfgStruct_DeisterUDL, ST_RFID_CfgStruct_LeuzeRFM,…) or also in the form of a configuration register (byte array). This selection can be made with the variable bUseCfgReg.

Further information on RFID reader configuration is summarized in the Configuration chapter.

Baltech:

pCfg	This pointer must contain the memory address of the configuration to be written. This must be the configuration structure ST_RFID_CfgStruct_BaltechMifVHLFile.
iCfgSize	This input variable indicates the length in bytes of the configuration data specified via the pointer.

Deister:

pCfg	This pointer must contain the memory address of the configuration to be written. This can be both a configuration structure and a configuration register.
iCfgSize	This input variable indicates the length in bytes of the configuration data specified via the pointer.
bUseCfgReg	If the input variable bUseCfgReg is set (TRUE), then a configuration register (byte array) can be addressed via the pointer pCfg instead of a configuration structure. By default a specific configuration structure is specified.
bUseCfgDefault	This parameter is relevant only if the configuration data is present in the form of a specific configuration structure. A configuration structure is not specifically an overall representation of the configuration register. The structure contains only the most important configuration parameters. If the input variable bUseCfgDefault is set (TRUE), then default values are used for the unspecified configuration parameters. Otherwise the value of this configuration parameter is not changed, because the last read values are reused.

Leuze:

pCfg	This pointer must contain the memory address of the configuration to be written. This can be both a configuration structure and a configuration register.
iCfgSize	This input variable indicates the length in bytes of the configuration data specified via the pointer.
bUseCfgReg	If the input variable bUseCfgReg is set (TRUE), then a configuration register (byte array) can be addressed via the pointer pCfg instead of a configuration structure. By default a specific configuration structure is specified.
bUseCfgDefault	This parameter is relevant only if the configuration data is present in the form of a specific configuration structure. A configuration structure is not specifically an overall representation of the configuration register. The structure contains only the most important configuration parameters. If the input variable bUseCfgDefault is set (TRUE), then default values are used for the unspecified configuration parameters. Otherwise the value of this configuration parameter is not changed, because the last read values are reused.

The following configuration variant is available only for Leuze electronic RFID readers.

iRegIdx	If a special index is specified on iRegIdx, then exclusively this index of the configuration register is changed/read. To this end, iRegGroup must additionally be specified as a single register.
iRegGroup	Three values are available: 0 to change/read the entire configuration register; 1 to change/read the indices 16#00-16#0F of the register; 2 to change/read an individual index of the register, whereby this must be specified with iRegIdx.
