6.2 Defining Trend Objects
Trend objects are defined as other dynamic objects in a block. The object can be
linked to up to six analog signals. As opposed to other objects, the trend object must
be named with a name of 1-8 characters. The first character must be a letter or a
number. Trend names may contain the characters A-Z, 0-9 and _. Otherwise, the
standard for file names in MS-DOS is followed. The following parameters are de-
fined for trend objects. Double-clicking Setup of terminal options in the Setup fold-
er in the Project Manager allows selecting whether trends are to be stored when
changed, or if all samples are to be stored. For further information, see the section
