The logbook contains a chronological list of triggering operations, device errors, and events,
which are assigned a time stamp and can be used to create a log. The log is stored internally
so that the causes can be evaluated at a later stage.
Three types of logbook are available. They can be read as data sets:
● Logbook - Triggering operations Data set 73
● Logbook - Events: Data set 75
● Logbook - Device errors: Data set 72
The current value "Operating hours - device" is entered as the time stamp.
You can find the object numbers of the relevant messages in the relevant data sets.
The last 21 entries are stored in the logbooks. The entries can be read out with the relevant
data sets.
The logbook is designed as a circular buffer. After 21 entries, the oldest entry is overwritten.
Logbook - Triggering operations
The "Logbook - Triggering operations" contains all the group faults. The object numbers of
the actual fault causes are entered, e.g. "Switching element overload".
Note that the "Logbook - Triggering operations" is deleted with the command "Delete
Logbook - Triggering operations"
The "Logbook - Events" contains all the warnings as well as certain actions.
Observe the following:
● "Incoming" and "outgoing" events are entered:
"Incoming" means: The event is occurring.
"Outgoing" means: The event is acknowledged.
The entries are differentiated in the data set by means of the sign:
(+: Incoming, –: Outgoing).
● The "Logbook - Events" is deleted with the command "Delete logbook - Events".
The "Logbook - Device errors" records all occurring device errors.
Please note that the "Logbook - Device errors" cannot be deleted.
