To show Pen 10 again, use the bitwise OR operator and the pens
decimal value:
PenMask = PenMask | 512
Specifying a start time
To specify an absolute trend start time, use the \StartTimeDate
control tag. The \StartTimeDate control tag overrides the time
specified in the Start Time field of the Trend dialog box. Create a
string input object so that the operator can enter the date and time of
the start time. 6.
To specify a relative trend start time, create an = (Equal) command
that uses the system\DateAndTimeInteger tag as the current time and
performs calculations relative to its value. The value that is added to or
subtracted from the current time must be in seconds.
Example: Specifying an absolute start time
The current display contains these objects:
A historical trend with a Control Tag folder called Trend
A string input object configured with the control tag
Trend\StartTimeDate
To specify a start time of 1:00 pm on January 1, 1998, the operator
enters this string in the string input object:
JAN 01 1998 13:00:00
