3、m the drive with separate commands”.It is not on-line and causes less load for the communication than other selections. Thus the contents of the fault logger are not updated even it is open on the desktop. By double-clicking with mouse the fault logger icon or by the Update Items-button the contents

4、 will be updated.PUT ON-LINE= is full time and real on-line connection. This is applicable also with the parameters and signals.But this causes more load for the communication, which should take into consideration in case by case.

5、ger) ABB Group - 5 -24-Jan-22 You can set x-axis length of the monitor or a datalogger at any time. X-axis length of a datalogger can also change automatically when the datalogger is uploaded. Note! If a datalogger has never been uploaded, DriveWindow does not know for sure the size of a datalogger

6、channel buffer. Thus DriveWindow does not do any checking about the x-axis length, until it knows more about the datalogger. When size of the datalogger channel buffer is known, DriveWindow does not accept improper setting of x-axis length.Interval, where you can change the logging interval of the c

7、urrent datalogger.Pre-Trig (ms), where you can change the number of values kept in the current datalogger before the triggering event. The value is given and shown as time, but the datalogger actually uses a count.Trig Hysteresis, where you can change the triggering level hysteresis, which is used i

8、n triggering the current datalogger.Trig Level, where you can change the triggering level, which is used in triggering the current datalogger.Trig Conditions (fault, warning, level etc).Trig Variable, where you can change OPC address of the variable, which is used in triggering the current datalogge

9、r.Status shows the state of the datalogger. Double-clicking toggles it on-line/off-line. Trigged By shows the triggering reasonScale channel 1; Two scaling methods available. Same method selected for Monitoring and Datalogger from FILE-menu:Graph/Preferences. Change the scale by double-click channel
