4-8 Drawing a Circuit Diagram with Pico
Creating and Modifying Connections
Relay contacts and relay coils are connected in Connect mode using the diagonal
wiring arrow (available in this mode). Use the arrow buttons to move the cursor
onto the contact field or coil field from which you wish to create a connection. Do
not position the cursor on the first contact field. At this position, the Alt button has
a different function (Insert circuit connection).
1.
1.1.
1. Press Alt to switch to Connect mode.
2. Use the left and right arrows to move the
diagonal arrow between the contact fields and coil fields and the up and down
arrows to move between circuit connections.
3. Press Alt to leave Connect mode.
Pico leaves Connect mode automatically when you move the diagonal arrow onto a
contact field or coil field which is already assigned. In a circuit connection, Pico
automatically connects relay contacts and the terminal to the relay coil if there are
no empty fields in-between.
When wiring more than three contacts in series, use one of 16 marker relays “M”.
Deleting Connections
1.
1.1.
1. Move the cursor onto the contact field or coil field to the right of the
connection that you want to delete. Press Alt to switch to Connect mode.
2. Press Del.
Pico will delete a connection. Closed connections that are adjacent are
retained.
If several circuit connections are connected to one another, Pico first deletes
the vertical connection. If you press Del again, it deletes the horizontal
connection as well. You cannot delete connections that Pico has created
automatically.
3. Close the delete operation by pressing Alt or by moving the cursor to a contact
or coil field.
IMPORTANT
Never work backward. Your circuit diagram may not perform as
you expect it to.
