4.6.6. The logic modules
These modules are the basis for the creation of a program for the safety application. They enable
the logical connection of the inputs with monitoring functions to the outputs. Only in the
“Funktionsplan” [Function Chart] view, it is possible to insert logic modules. Otherwise, the
corresponding module commands are disabled. This applies if the resources for a module are
already exhausted, e. g. after all timer modules have been inserted. You find a description of the
logic modules in the chapter “Logic
functions
”.
4.6.7. Circuit
The assignments in the function chart are achieved by linking the input
connectors and the output connectors of the functional modules. If necessary, one module output
can be connected with the inputs of other modules, but one module input may only be assigned
once. Furthermore, for technical reasons certain module groups cannot be interconnected. In case
of an invalid connection, the programme displays a corresponding warning.
Only rectangular control points can be created, i. e., the connecting lines always run horizontally or
vertically.
Creating the connection
1. Press the left mouse key to select a start connector.
2. The user can define the root and breakpoints by clicking in the free range.
3. With a second click the target connector is selected.
4. If automatic arrangement has been enabled, the connection and the blocks are
arranged automatically.
NOTICE:
Connection can only be selected with the mouse, and they can only be deleted with the Del-button.
Tip:
If all connections of a module shall be deleted, the corresponding function block can be
deleted. In this case, the connected terminals are automatically deleted
.
