Siemens SIMATIC RF300 System Manual page 433

Explanations:
• "LFD" is a measured value for the field strength that is determined in the transponder. The
lower the value, the higher the field strength.
• "FZP" counts interference pulses when communication with a transponder is not taking place
(e.g. electromagnetic interference caused by contactors, motors, etc.). Counter values can
also be generated when a transponder is located at the edge of the field even when there is
no external interference.
• "FZA" counts errors that can occur during reader-to-transponder communication. This can be
caused by unsuitable reader/transponder positioning (e.g. transponder on field boundary or
several transponders in antenna field) or external electromagnetic interference.
• "ANWZ" is the value for the time that the transponder remains in the antenna field before the
"Tag-Status" (MDS STATUS) with attribute "0x82" (mode 02) is executed. A time step is 10 ms.
The maximum time that can be recorded is therefore 2.5 s.
Attribute "0x83" (mode 03), corresponds to UDT 230
