IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
Tip
You can parameterize the read/write head with several transmission power values:
Command WP1UPT.00.06.00.14.00.32.00.64 sets 3 transmission power values for 20 mW, 50
mW, and 100 mW. Each read and write command is executed in succession for all 3
transmission power values. If one or more tags are found and successfully read/written for the
first transmission power, the command is still executed with all other transmission powers to
reach any other tags that may be available.
You can specify a maximum of 10 transmission power values. If several additional transmission
channels are selected (see "CD Transmission Channels" on page 50), all set powers are
executed on each transmission channel for each read or write command. See chapter 6.2.
Protocol Mode QV
Parameter QV toggles the output protocol between single frame and multiframe.
In single-frame protocol, the output corresponds to the Pepperl+Fuchs standard in LF and HF
systems. If there is more than one tag in the measurement range, status A is output as a warn-
ing.
In the multiframe protocol, each tag that responded is output. An output is then issued which
begins with status F, contains the number of responses, and completes the full command out-
put.
ParamTyp:
Default:
Value range:
Example:
WP1UQV.00.01.4D sets the protocol to multiframe.
RP1UQV.00.00 outputs the set protocol mode.
If QV = M, the following responses are made to a single read command (SR):
Response:
One read command was executed to which three tags responded. For each tag, the status, the
IDENTControl channel, the length of the UII, the UII, the length of the data, and the read data
are output. Then an output is issued with status F, the IDENTControl channel, and the number
of tags that responded.
<Luii> = Length of <UII> in bytes, 2 bytes
<Ldata> = Length of <data> in bytes, 2 bytes

QV = .4D
.53 = S for single-frame protocol
.4D = M for multiframe protocol
