Paso 4: Conectando los Bloques
In order to complete the circuit, the individual blocks must be connected to one another:
1. The tool must be selected if you
want to connect the inputs and outputs of
the function blocks to one another.
Now, point the mouse to a connection pin of
a block and click using the left mouse
button. Keeping the mouse button pressed,
move the mouse until it is pointing at the
pin that you want to connect to and release
the mouse button. LOGO!Soft Comfort then
connects the two pins together. This results
in a connection between two block pins.Use the same procedure for the other
connections.

Paso 11: Documentacin (1)
For purposes of program documentation, you can display all of the connectors, basic functions, and special
functions used in the program.
A list of all blocks used in the program is displayed using the
Edit -> Go to Blockmenu command. The list contains
information on the block number and the type of the block. For
example, you can display the special functions that you used. You
can enter the brief description of the block, I1, Q2, B02, etc., in
the search function, and you will be shown the position of theblock in the list. Clicking OK causes the block that you searched
for to be highlighted.

Paso 11: Documentacin (7)
Various connection lines must be separated when the program is divided onto several pages.
The connection lines can be easily separated using the selected cut tool. The interfaces are uniquely labeled by the
page number, block number, and input pin. By clicking on one of the interface wildcards again using the cut tool, the
separation is undone.

Q1(Drinking water supply)
You know that your program can run in LOGO!, but you still have to check whether it functions as intended. You may
also want to modify some parameters.You can experimentally change the input values, test the response to a power
failure, and compare your calculations or expectations with the actual output behavior.
SIMATIC Totally Integrated Automation
Paso 12: Prueba del Programa (2)
An excellent tool is available for testing your program.
1. Select the tool if you want to
test your program.
2. Once the simulation is activated, a
symbol bar for operator control and
monitoring of inputs and outputs is called.
A software switch is used to simulate a
power failure in order to test the retentive
features of the circuit behavior.
3. The input states can be modified by
clicking the button in the symbol bar (2) or
clicking on the inputs in the display.

The connection sequence can be tracked by
the change in color of the connection lines
from blue (low signal) to red (high signal).
This facilitates the detection and removal of
errors significantly.

Paso 12: Prueba del Programa (3)
As an additional aid for program testing, a particular switch functioncan be assigned to each input.
The context menu (right mouse click) can be used to assign an appropriate switch function to each of the inputs used
in the program. You can select from a momentary-contact switch, maintained-contact switch, and frequency input. For
frequency inputs, the simulated frequency setting in Hz can be entered. For analog inputs, the range and the starting
value is specified.
These parameters can also be changed and reviewed centrally using the Extras -> Simulation parameters menu
command.

Paso 13: Asignar un Password al Programa
In order to protect the program and the knowledge it contains, you can assign a 10-digit
password to be applicable to this program alone.
This password protects your program only on LOGO! Without the password,
you cannot change or view the program, only delete it. The password is also
needed to download a password-protected program to a PC.
To delete a previously assigned password, enter the old passwordand leave the
new passwordblank.
