Error description
4x 0xE4FE8C00
• Communication error between Ident profile and communication module. Handshake error.
Possible causes / action to be taken:
– The UDT of this communication module has been overwritten by other program sections.
– Check the parameter settings of the communication module in the UDT.
– Check the Ident profile command that causes this error.
– After eliminating the error, execute the "INIT" command.
• Backplane bus / PROFIBUS DP error occurred.
This error is only indicated when access monitoring has been enabled in the PROFIBUS con-
figuration.
Possible causes / action to be taken:
– Backplane bus / PROFIBUS DP bus connection was interrupted (wire break on the bus;
bus connector on the communication module was briefly unplugged)
– The backplane bus / PROFIBUS DP master no longer addresses the communication
module
– Execute the "INIT" command.
– The communication module has detected a frame interruption on the bus. The backplane
bus, PROFIBUS may have been re-configured (e.g. with HW Config or TIA Portal)
-- 0xE4FE8D00
• Firmware error
Possible causes:
The firmware update was not run completely.
• Internal communication error of the communication module/reader
Possible causes / action to be taken:
– Connector contact problem on the communication module / reader
– Hardware of the communication module/reader has a defect; → Send in communication
module/reader for repair.
– After eliminating the error, execute the "INIT" command.
• Internal monitoring error of the communication module/reader
Possible causes / action to be taken:
– Program execution error on the communication module / reader
– Switch supply voltage to communication module/reader off and on again.
– After eliminating the error, execute the "INIT" command.
-- 0xE4FE8E00 The current command was aborted by the "WRITE-CONFIG" ("INIT" or "SRESET") command for
the bus connector was pulled.
Possible causes:
• Communication with the transponder was aborted by "INIT".
• This error can only be reported if there is an "INIT" or "SRESET".
