Diagnostics and error messages
5.1 Error messages from the Ident profile / Ident instructions
5.1.2
Errors from the communications module/reader
The causes of these errors can, for example, be as follows:
• Errors have occurred in communication between the CM and the reader or between
the reader and the transponder.
• The communications module is unable to process the command.
Byte 3 of the "STATUS" is not relevant for the error messages.

Description
sage
(hex)
0xE1FE0100
Memory of the transponder cannot be written to
•
Transponder memory is defective.
•
Transponder EEPROM was written too frequently and has reached the end of its service life.
•
Transponder is write protected (Memory Lock)
0xE1FE0200
Presence error
The transponder has moved out of the transmission window of the reader. The command was execut-
ed only partially.
Read command: "IDENT_DATA" has no valid data.
Write command: The transponder that has just left the antenna field contains an incomplete data
record.
Possible causes:
•
Operating distance from reader to transponder is not being maintained.
•
Configuration error: The data record to be processed is too large (in dynamic mode).
•
With timeout: No transponder in the antenna field
0xE1FE0300
Address error
The address area of the transponder has been exceeded.
Possible causes:
•
Start address at command start is incorrectly set.
•
Transponder is not the correct type.
•
The area to be written to is write-protected.
Freeport: Address ≠ "0x0000", "0x0002", "0xFFFF"
0xE1FE0400
Initialization error
Transponder is unable to execute the initialization command.
Possible causes:
•
Transponder is defective.
0xE1FE0500
The transponder memory is full.
