9.5.2 Filtering logbook entries
The logbook adds new entries to the ring buffer after they have been passed through a
parameterisable filter. This filter helps you to exclude certain events from being entered into the
logbook which would trigger a certain error response (fault, trouble, warning, information, etc.).
C00169
(bit 1 ... bit 6) includes a bit coded specification of the events which are to be entered into
the logbook. In the Lenze setting, all events are entered into the logbook.
Counter for multiple entries
In order to prevent the ring buffer from overflowing with identical
errors with frequent occurrence
e.g. during commissioning, identical errors will not lead to new line entries in the configuration of
the logbook in the Lenze setting. Instead, one counter will be counted up for this error.
• The time of the error is always the time of its first occurrence. Hence, a new logbook line will
only be generated if a new error occurs.
• The error counter can be deactivated by resetting bit 9 in C00169
.
In C00169
, bit 9 and bit 10 determine the logbook update in case of similar errors.
Meaning of bit 9 / bit 10:
• Bit 9: Error counter
• Bit 10: Update of the logbook line
In the Lenze setting (C00169
= 0x067E), bits 9 and 10 are active.
The following cases can be distinguished depending of the activation of bit 9 and bit 10:
1. Bit 9 inactive, bit 10 active/inactive
• Every time an error occurs, a new line is created in the logbook.
• The setting of bit 10 has no effect!
2.Bit9 active, bit10inactive
• Only one line is created for the first occurrence of the error. If the error occurs again, only the
error counter in the line is increased.
3.Bit9 active / bit10active (Lenze setting)
• The time of the last occurrence of similar
errors is logged.
• The time stamp and the optional measured values are updated in the error line of the
logbook.
• When the count value = 255 is reached and an error occurs again, a new line is created.
9.5.3 Automatic recording of device-internal signals at the time the error occurs
For purposes of error analysis, two optional device-internal digital signals and an analog signal
(16 bit) can be recorded at the time the error occurs.
• The digital signals to be recorded are selected in C00163/1
and C00163/2.
• Scaling of the value recorded: 0 ≡ FALSE; 1 ≡ TRUE
 Note!
Events with the "No response" setting are not entered into the logbook.
