IUH-F190-V1-*
Operation
Transmission Power "Power Transmit" PT
This parameter sets the transmission power in mW or reads out the set transmission power.
ParamTyp:
Default:
Value range:
Example:
WP1UPT.00.02.00.32 sets the transmission power to 50 mW
RP1UPT.00.00 reads out the currently set transmission power
Higher detection range if you increase the transmission power.
Possible excessive detection ranges if you increase the transmission power.
Lower detection range in reflective environments if you increase the transmission power.
Potential interference with adjacent read/write heads due to increased detection range.
Note!
You can operate the IUH-F190-V1-* read/write head only with internally specified transmitting
power. You can use the command WP1UPT.00.02.xx.xx in the software to enter any
transmission power within the specified range of values. The read/write head automatically
sets the transmission power to the next lowest value available. Any entries outside the specified
value range are returned as errors. Command RP1UPT.00.00 allows you to read out the power
value that is currently set.
Tip
You can parameterize the read/write head with several transmitting power values:
Command WP1UPT.00.06.00.14.00.32.00.64 sets three transmission power values for 20 mW,
50 mW, and 100 mW. Each read and write command is executed in succession for all three
transmitting power values. If one or more tags are found and successfully read/written for the
first transmitting power, the command is still executed with all other transmitting powers to
reach any other tags that may be available.
You can specify a maximum of ten transmitting power values. If several additional transmission
channels are selected (see "Transmission Channel CD" on page 50), all set powers are
executed on each transmission channel for each write or read command. See chapter 7.2.
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
warning.
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
output.
ParamTyp:
Default:
Value range:
Example:
WP1UQV.00.01.4D sets the protocol to multiframe.
RP1UQV.00.00 outputs the set protocol mode.
