IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
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.
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
