23.12 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 Operation
Column 1
• NO contact
• NC contact
-| |-
-|/|-
Column 2
(optional)
NOT
Rising edge
Falling edge
Assign

Reset
-|NOT|-
-|P|-
-|N|-
-( )
-(S)
-(R)
Column 3
(only possible if no assign, set or reset
operations were specified in the second
column)
Assign
Set
Reset
-( )
-(S)
-(R)
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.
