Data that can be logged
Logging on Logging is activated or deactivated.
Alarm status change Incoming and outgoing alarms are logged.
Keyboard actions All actions on the operator panel front and on an external keyboard
are logged.
Channel status change NC/PLC states are logged via the information channel status. If this
information can be obtained in a timely manner, in many cases
these states can be used to verify the operation of the machine
control panel.
Window switchover The form and dialog names (assigned by the programmer) are log‐
ged each time a window is opened or closed.
Writing NC/PLC data The writing of NC and PLC variables is logged.
File access Copying to the NC is logged.
Function calls in the NC (PI
service)
Some program calls, for example, ASUB, are logged.
Curr. program status Additional information for particular events is activated. For impor‐
tant alarms that require NC stop, NC start, or NC reset, actual val‐
ues and the current block are recorded for example.
The
program ascertains which
channel and which spindle are used
for the additional information.
Write interval file Settings for updating files:
● "automatic": The action log
saves the information to an internal
buffer. If the buffer is full the entries are written to the CF card.
The entries may be lost when the control is switched off.
● "after every event": All entries are backed up immediately, this
prevents data loss due to a power failure or similar.
Notice: As CF cards only permit a limited number of write
accesses, this setting is not recommended for normal operation.
● "time-controlled": New entries are backed-up for a particular
length of time. An additional input field appears in which you can
specify a time in seconds.
Save log as file for alarm(s)The alarm numbers for which a "crash log" is generated are speci‐
fied. The alarms are entered separated by a comma.
Generating a crashlog file
The "actual_crashlog.com" is a backup file of the actual log when a critical event occurs (for
example, emergency stop alarm).
The file is then no longer stored in the ring buffer of the action log and can no longer be
overwritten with new entries.
The entries in the crash log file are only overwritten when yet another critical events occurs.
At the beginning, the file has no entries and is only written to after the following event:
● The alarm entered in the "Save log as file for alarm(s)" entry field is output.
