Inserting and editing networks
You can create a new network and then insert operations (bit operation, assignment, etc.) at
the selected cursor position.
Only empty networks can be edited. Networks, that already include statements, can only be
deleted.
A simple, single line can be edited for each network. You can create a maximum of 3
columns per network.
Column
Column 1
Column 2
(optional)
Column 3
(only possible if no assign, set or reset oper-
ations were specified in the second column)
Note
Logical AND (serial contact) and logical OR (parallel contact) are not possible.
The bit combinations comprise one or several logical operations and the assignment to an
output / bit memory.
If the cursor is moved further to the left with the arrow key, the type of assignment or a logic
operation can be selected. A further logic operation cannot be placed to the right of an
assignment. A network must always be terminated with an assignment.
