Read/Write Commands - Pepperl+Fuchs IUH-F192-V1 Series Manual

IUH-F192-V1-*
Operation
Note!
When writing to the UII/EPC area (MB = 1), note that it is not possible to write to the CRC. The
first writable address is 0x0001. The protocol control word <PC> begins at this address. Use
the command #SW.
Enhanced Write Words EW
This command continuously attempts to write <WordNum> 32-bit words from the address
<WordAddr>. If the command was executed successfully, a status 0 is reported. If there is no
tag in the detection range, or if the tag leaves the detection range, a status 5 is reported.
Command:
Response:
Example:
EW1000101ABCD continuously writes the 4-byte long word "ABCD" from memory address
"0001".
Note!
The memory bank (MB) parameter defines the bank accessed by this command. see
"Memory Module for Tag Accesses to the "Memory Bank" MB" on page 58.
Note!
16-Bit Read/Write Commands
The read/write commands SR, ER, SW, and EW are interpreted as 16-bit versions by means of
a preceding # symbol.
The 16-bit read/write commands behave in the same way as the 32-bit versions.
16-bit commands write or read a word with a length of 2 bytes.
32-bit commands write or read a word with a length of 4 bytes.
Example:
#SW1000202ABCD corresponds to SW1000101ABCD
Kill UHF Tag KI
This command sets a UHF tag to a state where no further access is possible. The command
can be executed only if a valid password has previously been set in segment Bank 00 via the
command SW. See chapter 3.2.3. The password must have at least 1 non-zero bit.
Command:
Response:
<UIILength> = Mask length for the UII/EPC in bits, values: 00 ... FF, always begins at Address 0.
The information is entered as 2 hex
<UIIData> = Specification of the mask for the UII, in octets
<PassWord> = Password for killing a UHF tag, 4 octets
<RecomBits> = Recommission bits, always set to zero
