• Every line in the circuit diagram forms a rung. With the
display system up to 256 rungs can be wired in a circuit
diagram
• Connections are used to produce the electrical contact
between relay contacts and the coils. They can be created
across several rungs. Each point of intersection is a
connection.
• The number of free bytes is displayed so that you can
recognise how much memory is available for the circuit
diagram and function blocks.
Display system circuit diagram display
For greater legibility, the circuit diagram display of the
display system shows two contacts per rung or one contact
plus a coil in series. A total of 16 characters per rung and
three rungs plus the status line can be displayed
simultaneously.
You can move between the contact fields with the
úí cursor
buttons. The number of the rung and the contact are
displayed in the lower status line.

• In STOP mode it is used to edit the circuit diagram.
• In RUN mode it is used to check the circuit diagram
using the Power flow display.
