‘Extras’ ‘Step Attributes’

With this command you can open a dialog box in which you can edit the attributes for the marked step.

You can take advantage of three different entries in the step attribute dialog box. Under ‘Minimum Time’, you enter the minimum length of time that the processing of this step should take. Under the ‘Maximum Time’, you enter the maximum length of time that the processing of this step should take. Note that the entries are of the TIME type, so you use a TIME constant (i.e. T#3s) or a variable of the TIME type.

The time settings are also accessible in dialog ‘Extras’ ‘Time Overview’.

Under ‘Comment’ you can insert a comment to the step. In the ‘Sequential function chart options’ dialog which you open under ‘Extras’ ‘Options’, you can then define whether comments, the time setting or nothing is displayed for the steps in the SFC editor. On the right, next to the step, either the comment or the time setting or none of both will appear.

Those attributes which are not displayed because of the options settings, can - additionally to the step name - be displayed in a ‘Extras’ ‘Options’, which appears when the cursor is placed on the upper resp. lower right corner of the step box.

If the maximum time is exceeded, SFC Flags are set which the user can query.

The example shows a step whose execution should last at least two, and at the most, ten seconds. In Online mode, there is, in addition to these two times, a display of how long the step has already been active.
