3.15.3 15-2* Historic Log
View up to 50 logged data items via the array parameters
in this parameter group. For all parameters in the group,
[0] is the most recent data, and [49] is the oldest data.
Data is logged every time an event occurs (not to be
confused with SLC events). Events in this context are
dened as a change in 1 of the following areas:
•
Digital input.
•
Digital outputs.
•
Warning word.
•
Alarm word.
•
Status word.
•
Control word.
•
Extended status word.
Events are logged with value and time stamp in ms. The
time interval between 2 events depends on how often
events occur (maximum once every scan time). Data
logging is continuous, but if an alarm occurs, the log is
saved and the values can be viewed on the display. This
feature is useful, for example when carrying out service
following a trip. View the historic log contained in this
parameter via the serial communication port or via the
display.

event occurred. Time is measured in
ms since frequency converter start. The
maximum value corresponds to
approximately 24 days, which means
that the count restarts at zero after
this time period.
