If modules that have already been connected shall be added to a group by shifting, you should
proceed as follows:
1. Shift the group block over the function block. The affected connections must all be situated in
the group file.
2. Choose the modules, and shift them in the group module by one grid position
The following block types cannot be part of a group. They are filtered, when the modules are
shifted to the frame section:
•
Input modules
•
Output modules
•
All function blocks preceeding in the function chart (e. g. encoders,
analogous modules, I/O)
•
Signal channel modules
The maximum is determined by the size of the sheet..
The export to the library function is shown by a click on the grop with the right mouse button.
3. Adding an interface to an input / output
You can insert a block for a group interface by draggin a group output / a group outputin th library
of thegroup interface and inserting it ino the corresponding group block (or in the group in the
function chart). After you have added a block to a group, the group interface is added.
For further information cf. the chapter “Group interface “
4. Creating conncetions
-cf. the chapter
“Circuit”
.
5. Connecting the group interface
Via the above-mentioned interface, the function blocks within a group can only be connected to the
function elements outside the group frame. In the interface, the connection type can be selected
arbitrarily. However, the same connection constellation is needed for the import of the group into a
different function block. The interface blocks enable a description of both, input and output of rhe
function group. The description should be documented in the comment.
Tips:
•
If possible, during which the group(s) remain in the active status should be as short as
possible.
•
Activate as few groups as possible in the function chart.
•
Do not shift any groups in the function chart.
•
If possible, only edit one group in the function chart.
•
Deactivate the groups before saving .
•
Create connections as late as possible.
