Draw a Circuit Diagram with Pico 4-55
Example Programs
The Pico circuit diagram is created using ladder logic. This section
contains a few programs intended to demonstrate possibilities for your
own circuit diagrams.
The values in the logic table have the following meanings for contacts:
• 0 = make contact open, break contact closed
• 1 = make contact closed, break contact open
For relay coils Qx:
• 0 = coil not energized
• 1 = coil energized
Negation
Negation means that the contact opens, rather than closes, when it is
actuated (NOT circuit).
In the Pico circuit diagram, press the Alt button to toggle contact I1
between break and make contact.
Permanent Contact (Unconditional Rung)
To energize a relay coil continuously, make a connection of all contact
fields from the coil to the leftmost position.
