12.1 Diagnostics
Diagnostic messages (reader diagnostics)
The following settings of the diagnostic messages are available to you:
● None
No further diagnostic data is reported.
● Hard errors
Critical hardware errors/faults are reported by the S7 diagnostics. Extended diagnostic
messages are generated in the case of the following events.
– Hardware fault (memory test)
– Firmware error (checksum)
– Break in connection to reader
– Fault in power supply to the readers
– Short-circuit/break, if supported by hardware
– Firmware update (message at start/end)
● Hard / soft errors
Critical hardware errors and errors that occur during command processing are reported
by the S7 diagnostics. In contrast to the hard errors, errors that arise during command
processing are also reported in this case.
Please note that messages triggered by command processing are automatically taken
back after 3 seconds.
Differentiation of diagnostic interrupt messages
With the diagnostic interrupt messages, a distinction is made between incoming and
outgoing diagnostic interrupts.
● Incoming diagnostic interrupt
An event occurs and triggers an alarm.
● Outgoing diagnostic interrupt
The event is no longer current, a diagnostic message is output. For events that only exist
momentarily, the reset is delayed by 3 seconds.
