When RFID
systems are used, questions always arise regarding the operating
distance such as
"How fast can the products run past the read-write heads?" or
"How close do the products have to be when they run past the
read-write heads?"
In general, a great deal of uncertainty exists regarding the
possibilities for using an RFID system.
General information such as "Recommended read-write interval" or
"Transfer rate = 0.5 ms/byte" is not usually sufficient
for evaluating use of the equipment in a specific application,
because application variables such as data quantity,
speed and distance result from complex interaction between the
read-write heads and data carriers.
With the BL-Ident Configurator it is now possible
to simulate any specific application
and experiment on-screen with various equipment combinations.
The possible ranges and limitations of any specific combination can
be found quickly
by setting the application parameters and using trial-in-error.
Standard function blocks are available for
integration of the system into the various bus and control
environment such as PROFIBUS-DP, Ethernet and
DeviceNet™. This simplifies the complex programs for the various
read-write commands and allocation of the channels significantly.
