Drawing a Circuit Diagram with Pico 4-5

Connections are used to produce the electrical continuity between relay contacts and

the coil. Connections can be created across several rungs. Each point of intersection

is a connection. The circuit diagram display performs two functions:

• 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

Saving and Loading Circuit Diagrams

There are two ways of saving circuit diagrams in Pico:

• By saving to a memory module

• By saving to a PC running PicoSoft programming software

Once they are saved, programs can be reloaded into Pico, edited, and run. All

circuit diagram data is saved in Pico. In the event of a power failure, the data is

retained until the next time it is overwritten or deleted.

Memory Module

Each memory module can contain one circuit diagram, which is inserted into the

Pico interface. How a memory module works and a description of how to transfer a

program to the module is described in Saving and Loading Circuit Diagrams on

page 5-1.

PicoSoft

PicoSoft is an optional PC program that allows you to create, store, and manage

Pico programs. Completed programs are transferred between your PC and Pico via

the connecting cable. Once you have transferred a circuit diagram, you can

monitor the program running in Pico directly from your PC. Details on the

program and transferring circuit diagrams are given in Saving and Loading Circuit

Diagrams on page 5-1.
