10.3.2 Configuring the Ident profile (RFID standard profile)
For a detailed description of the parameter assignment and commissioning of the RFID
standard profile FB, refer to the relevant RFID function manual (J31069-D0179-U001-A1-
0018).
The following blocks are required in the S7 project:
●
"RFID standard profile FB"
(FB101, FB116 or FB132 depending on the length of the data to be processed)
● "Instance DB RFID standard profile", field that can hold 10 commands.
A command is a complex variable of the type "PIB_COMMAND"
RXBUF and TXBUF for result or job data (command data area).
Input parameters
The following input parameters have a different meaning from the description in the function
manual of the RFID standard profile:
Variable Value/description
INIT For information on initializing the ASM or on acknowledging a group error of the reader,
refer to chapter Group errors (Page 267).
Output parameters
The following output parameters have a different meaning from the description in the
function manual of the RFID standard profile:
Variable Value/description
RPTACT Not supported
TPC No significance
TP No significance
UIN0-1 See description Status displays of the MV reader (Page 245)
Initialization
During initialization (INIT), the Ident profile automatically executes the "WRITE-CONFIG"
command (see function manual for RFID Standard Profile, RFID Systems J31069-D0179-
U001-A2-0018).
The parameter values of the "WRITE-CONFIG" command depend on whether the Ident
profile is used with or without a communication module.
