SMX Programming Manual for the SMX Module - OEM Automatic AB

Preparing the Wiring
The assignments in the logic diagram are created by linking the inPort and
outPort connectors of the functional modules. An outPort of a module may, if
necessary, be multiply connected with inPorts on other modules, whereby any inPort
must only be assigned once. Apart from this, certain module groups cannot be
interconnected for technical reasons. In case of an invalid connection the program
will display a corresponding message.
Connection set-up:
Select a start connector with the left mouse button
Hold the left button activated and position the mouse pointer
deactivate the button when the pointer is on the target connector
Note: Connections can only be selected with a mouse click or by choosing a
connector.
Tip: If all connections of a module are to be deleted, one should delete the
associated function block. The connected connections will in this case be
automatically deleted.
Automatic connection
The editor routes a new connection automatically. The graphics display can be varied
and the overall presentation optimized by simply moving the function blocks. In
complex diagrams it may happen that a connecting line will intersect with a function
block. This behaviour has no influence on the internal function of the linkage.
User defined connection
A command for the drawing of user defined connecting lines is additionally available.
These will remain existent, until the dislocation of an associated function block forces
the recalculation of the control points (see automatic connection)
A user defined connection is set up as follows
1.) either by selecting the connection to be edited and invoking the command:
"User defined connecting points" in the "Edit" menu.
2.) or by opening the context menu (right mouse button) while the mouse pointer
is positioned on the corresponding connection and selecting the command
"User defined connecting points".
3.) Input of control points for orthogonal connecting lines , i.e. the connecting lines
always run horizontally and vertically. The program connects the entered
points, until the drawing command is terminated.
4.) Termination of command with the Enter-key (Return) and drawing of the
connection by the editor.
Note: The program matches the first and the last control point to the
associated function block connector. The inPort and outPort connector is not
considered a control point and does therefore not need to be specified.
