Inventory Power
Ramp
This algorithm increases the radiated power automatically in steps if the speci-
fied number of expected transponders is not detected in each inventory. The
power is increased until the required number of transponders is detected or
until the specified maximum value is reached. This, for example, compensates
for fluctuating radio conditions.
This algorithm is only used when taking inventories (e.g. "presence mode" in
PROFINET operation). With read/write commands, the algorithm is not start-
ed.
The step size of the individual increases is calculated as follows: Boost max /
Inventories
Example:
Boost max = 5 dB, Inventories = 10 ⇒ Step size = 0.5 dB
Expected Tags The value specifies the minimum number of transponders
that should be identified per read point in every inventory.
If this value is not reached, the radiated power is in-
Boost Max [dB] The value specifies by how many dB the radiated power
can be increased as maximum.
Inventories The value specifies the number of inventories to be taken
until the maximum radiated power is reached. If the speci-
fied number of transponders is identified before the max-
imum radiated power is reached, the radiated power is
not increased to the maximum value.
