Drawing a Circuit Diagram with Pico 4-9

Inserting and Deleting a Circuit Connection

The LCD display shows four of the 41 or 121 circuit connections in the display at

the same time. Pico automatically scrolls the display up or down to show hidden

circuit connections—even empty ones—if you move the cursor past the top or

bottom of the display.

A new circuit connection is added below the last connection or inserted above the

cursor position:

1.1.

1. Position the cursor on the first contact field of a

circuit connection.

2. Press Alt.

The existing circuit connection, with all its additional

connections, is shifted down. The cursor is then

positioned directly in the new circuit connection.

Deleting a Circuit Connection

Pico only removes empty circuit connections, i.e. those

without contacts or coils.

1.1.

1. Delete all the contacts and relay coils from the circuit connection.

2. Position the cursor on the first contact field of the empty circuit connection.

3. Press Del.

The subsequent circuit connection(s) is “pulled up” and any existing links between

circuit connections are retained.

Using the Cursor Buttons as Inputs

With Pico, you can also use the four cursor buttons as soft inputs in the circuit

diagram.

The buttons are contacts P1 to P4 in the circuit diagram.

The P-Buttons can be activated and deactivated in the

System menu.

The P-Buttons can also be used for testing circuits or manual

operation. These button functions are also useful for

servicing and commissioning purposes.

Example 1

A lamp at output relay Q1 is turned on and off via inputs

I1 and I2 or using cursor buttons up and down.

I2---------{Q4

I1---------SQ1

I2---------RQ1
