Configuring The Program Segments - gefran 3850T Use And Installation Manual

4. CONFIGURATION
Program Base configuration page (4) allows you to con-
figure up to 16 output events that can be enabled (ON) or
disabled (OFF) in the various steps.
Output events can take the ON or OFF status or maintain
the previous state and can be associated with any segment
of the program.
To associate an output event with a digital resource, touch
the line and select the variable from the pop-up list that
opens. For details on the pop-up window, see the descrip-
tion on page 103.
Resources 1 to 8 may be set, among the outputs managed
for each segment, only by a level 2 user (admin or manufac-
turer), while resources 9 to 16 may be set by any user.
Page (5) of Basic program configuration
permits addition of variables to the recipe and memorisa-
tion of their values. These values are updated whenever
a change is made when the programme is loaded in the
memory.
When the programme is loaded, the "Recipe" variables are
reinitialised with the values they had at the time of the latest
change with the programme loaded in memory.
These auxiliary variables may be used, for example, in GET-
logic, to initialise counters or default values.
You may, for example, use a "counter" user variable which
is incremented by logic in the "Prog1" programme at every
external impulse. When working with the "Prog1" pro-
gramme, the counter will reach the value 50 and it will be
memorised in "Prog1". The programme is then removed
from memory, and the variable counter may be changed to
80 by any other logic.
When Prog1 is called up in memory in the future, the vari-
able counter will be written to the value 50.
The variables used are retentive.
Use of variables that frequently change their value while the
programme is loaded in memory is not recommended.

To define a variable, touch the line and select the variable
from the pop-up list that opens. For details on the pop-up
window, see the description on page 103.

4.13.3.2. Configuring the Program Segments

The Segments page let you configure each segment of the
program.
Each program can handle up to 4 synchronous profiles, i.e.
profiles that use the same time base for segment change.
Segments can belong to groups of contiguous segments
that can be repeated.
Touch the icon to open a pop-up window that allows
you to:
• Create a new segment before or after the selected
segment (highlighted in green).
• Configure the status of input and output events while
running the segment.
• Configuring segment profiles.
• Deleting the segment.
To create a new segment touch New before or New after
depending on whether you want the new segment to ap-
pear before or after the selected segment. When creating
the first segment, the choice is indifferent.
