Drawing a Circuit Diagram with Pico 4-11

Switch on I3.

In the power flow display, current-carrying connections

are thicker than those that are not powered.

You can follow a current-carrying connection across all

circuit connections by scrolling the display up and down.

The power flow display will not show signal fluctuations in the millisecond range.

This is due to the inherent delay factor of LCD displays.

Coil Functions

You can set the coil function to determine the switching behavior of relay coils. The

following coil functions are available for relays Q, M, S and D.

The marker relays M and S are used as “flags”. The only difference between them

and the output relay Q is that they have no output terminals. The functions of

timer and counter relays are explained in the relevant relay description. The coil

function { (output energize) must only be used once on each coil. The last coil in

the circuit diagram determines the status of the relay.

To ensure proper operation of all relay states, only assign the same coil function

once to a relay (S, R).

Exception: The coil function can be used properly several times when using jumps

to structure the circuit diagram.
