4.14.3 15-2* Historic Log
View up to 50 logged data items via the array parameters
in this parameter group. Data is logged every time an
event occurs (not to be confused with SLC events). Events
in this context are defined as a change in 1 of the
following areas:
•
Digital inputs.
•
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
MG06J202
Programming Guide
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.
