8.1.1
Meaning of the parameter bits
The default values of the firmware, the DTM and the EDS file are shown in
bold
type. The
default values for PROFINET may differ.
Designation
Meaning
Operating mode (OMRFID)
0: Deactivated
1: UHF compact
2: UHF extended
Diagnostic input filter (DID)
0: All diagnostic messages on
1: Diagnostic messages off
Command repetitions in the
event of an error (CRET)
Number of command repetitions after an error message, default setting: 2
Length of write data (WDS)
Size of the write data, default setting depends on the selected interface and
fieldbus
Length of read data (RDS)
Size of the read data, default setting depends on the selected interface and
fieldbus
8.1.2
Setting Continuous presence sensing mode
Set adaptions to the Presence sensing behavior in the DTM.
Optional: Set the grouping of the EPCs via the
Start address
parameter:
0: Grouping inactive
1: Grouping active (same EPC is not recorded again, only the counter incremented in the
header)
Execute the
Continuous presence sensing mode
command.
a
The read/write head is switched to Presence sensing mode and sends all received data to
the interface as soon as at least one tag is located in the detection range.
a
The data received from the read/write head is stored in the FIFO memory of the interface.
Send the
Idle
command (0x0000) in order to then read data from the buffer of the
interface.
NOTE
The
Continuous presence sensing mode
command also stays active after the Idle
command is sent.
To pass on data from the FIFO memory of the interface to the controller, execute the
Get data from buffer
(0x0011) command. The length of the data must be less than or
equal to the value of the available data bytes (BYFI). Depending on the length of the data,
it is no longer used for grouping.
NOTE
If Grouping is active: Only read data from the buffer if the number of available bytes
is stable. If stable data was fetched, the command can be terminated by means of a
reset since the grouping is no longer based on the fetched data and therefore old
EPCs can be detected again.
Do not carry out the reset until the data has been successfully read from the buffer.
To end Continuous presence sensing mode and clear the FIFO memory of the interface
send the
Reset
command (0x0800).
