•
Presence error: A transponder has passed by a reader without being processed by a command.
•
This error message is not reported immediately. Instead, the communications module is waiting
for the next command (read, write). This command is immediately replied to with this error. This
means that a read or write command is not processed. The next command is executed normally
again by the communications module.

An init_run from the Ident profile also resets this error status.
•
Bit 2 is set in the OPT1 parameter and there is no transponder in the transmission window.
