4.4.2
Combination of UHF read/write heads and tags
The UHF read/write heads form a transmission zone for which the size depends on the combin-
ation of read/write head and tag. The listed maximum read/write distances only represent typ-
ical values under laboratory conditions without the effect of materials. The achievable dis-
tances may be different due to component tolerances, mounting location in the application,
ambient conditions and the effect of materials (particularly metal).
For this reason, the application must be tested in all cases under real conditions (particularly
with read and write operations in motion).
4.4.3
Multiprotocol function
The devices can be used in the following three Ethernet protocols:
n
Modbus TCP
n
EtherNet/IP
n
PROFINET
The Ethernet protocol used must be selected in the CODESYS project.
Manual protocol selection
The protocol must be defined manually in the CODESYS program. After that only read access to
the device is allowed with the other protocols. Manual protocol selection thus also provides an
additional permanent locking feature.
4.4.4
Data transfer to the PLC
In every write or read cycle, up to 128 bytes can be transferred on each channel. The data must
be fragmented in order to transfer more than 128 bytes. The amount of data transferred per
read or write cycle can be set as follows for different Ethernet protocols:
PROFINET
EtherNet/IP
Modbus TCP
n
8 bytes
n
16 bytes
n
32 bytes
n
64 bytes
n
128 bytes
(default setting)
n
16 bytes
n
64 bytes
n
128 bytes
(default setting)
n
128 bytes (permanently set)
Adjustable fragment size:
n
8 bytes
n
16 bytes
n
32 bytes
n
64 bytes
n
128 bytes
(default setting)
4.4.5
RFID channels – operating modes
Two different data interfaces can be selected for the RFID channels:
n
UHF compact: Transfer of up to 128 bytes possible, recommended for single tag applications
n
UHF extended: Transfer of more than 128 bytes possible, recommended for multi-tag applic-
ations
