8.8 RFID channels — overview of commands
RFID commands are initiated via the command code in the process output data of an RFID
channel. The commands can be executed with or without a loop counter function. The loop
counter must be set individually for each new command.
NOTE
After commands are executed without the loop counter function, the device must
be reset to the Idle state before a new command is sent.
After a command is executed, send an idle command to the device.
