The reader ensures inductive communication with the transponders, and handles the serial
connection to the communication modules or the 8xIQ-Sense module.
Communication between the transponder and reader takes place over inductive alternating
The transmittable data volume between reader and transponder depends on:
● the speed at which the transponder moves through the transmission window of the
● the length of the transmission window.
● the RF300 transponder type (FRAM, EEPROM).
● the use of ISO transponders
With the following readers, you can also use ISO tags:
● SIMATIC RF310R reader (with RS422 interface)
● SIMATIC RF380R reader
The readers must either be parameterized for the RF300 or ISO mode. The parameterization
is done with the aid of the RESET message frame (INIT-Run).
You can find more detailed information on the software parameterization in Product
Information "FB 45 and FC 45 input parameters for RF300 and ISO transponders"
(http://support.automation.siemens.com/WW/view/en/33315697) or the Function Manuals
FB 45 (http://support.automation.siemens.com/WW/view/en/21738808) and
FC 45 (http://support.automation.siemens.com/WW/view/en/21737722) as of the A3 edition.
ISO functionality is only possible with certain reader MLFBs.
Only the SIMATIC RF310R and SIMATIC RF380R readers with the MLFB 6GT2801-xxBxx
are suitable for operating with ISO tags.
