Unlike TAB format, address masks and "*" operator entries are accepted in Long
Format, LFRM.
This allows listing of logged values from specific, or all, DP Value Logs covering a
certain time span.
Under the address (TA, UA) the information text as entered in point parameter TXI or
TXI2 appears.
This allows fixing the decimal point by entering the number of digits before or after the
point i.e. the value is rounded up or down to the number of decimal places defined.
•
A negative entry determines the number of places
after
the point
•
A positive entry defines the number of places
before
the point.
However, for DATA PROCESSING specifying only the number of decimal places (-4..0)
after the point is of importance.

The initial start of recording a DP Value Log is taken as the default time.
If several 'Series' are output in tabular format the start time of the last specified DP
Value Log is taken as the default time.
Start times may be changed in different ways:
Input of date and time.
"Today's" date is the default value, only the time is changed.
The date is changed and time automatically set to "00:00" hours.
Number of hours, days or months preceded by a minus sign.
Example: Input of "-24 Hrs" means, list the relative logged values from the
previous 24 hours up to the present time.
