Scan Mode Function Extension For Ascii Readers - Siemens SIMATIC Ident RF200 Operating Manual

Scan mode function extension for ASCII readers

The scan mode function extension retains the original function of the RF200 ASCII readers.
The extension adds the SYSTEM command to the existing command set. Using this
command, you can switch the readers retentively to scan mode. This means that the
switchover to scan mode is stored in a failsafe manner on the reader.
Once the readers have been switched to scan mode, the RF200 ASCII readers operate in
exactly the same way (autonomously) as an RF300 scan mode reader. It is not necessary to
restart the reader. The reader LED shows you which operating mode the reader is in.

Using the parameter assignment frames, you can also store all other parameters retentively
in the reader (e.g. transmission rate, data to be read, etc.). The scan mode parameter allows
you to reset the readers to basic functionality by means of the parameter assignment frame
("scan mode = 0x02"). You can transmit the frame via the terminal program as well as from
the application.
