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
recognize how much
memory
is available for the circuit
diagram and function blocks.
EZD circuit diagram display
For greater legibility, the circuit diagram display of the EZD
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
ú í
cursor
buttons. The number of the rung and the contact are displayed
in the lower status line.
