Enhanced buffered fixcode (EF)
Command:
Response:
The R/W head makes attempts until successful to read a read only code. Only data that
changes is transferred via the interface, i.e. the R/W head transfers data whenever it reads a
new read/write tag or whenever it reads a read/write tag where there was previously no
read/write head within the detection range.
The status '05h' (read command) is output whenever a read/write tag leaves the detection
range.
The length of the read only code that is output depends on the tag type. See table "Supported
Tag Ty pe s " on p ag e 5 8 .

Table 7.14 * this byte is only used with the TCP/IP and MODBUS TCP/IP protocol.
1) The telegram length depends on length of the read only code from the tag.
2) N = <FixLen> + 6; Ethernet/IP: N = <FixLen> + 4
