Counter Up and Down counter
A look at the circuit diagram shows that the switch S1 triggers the counter pulses. SwitchS2 determines whether the counter increases or decreases. When the counter statusreaches a value >= 5, the light switches on.
Description of the function:
With every positive edge at input Cnt the internal counter increments (Dir = 0) or
decrements (Dir = 1) by one count. Output Q is set to 1 when the internal value is greater
than or equal to the value specified in Par. You can use reset input R to reset the output and
the internal count value to the start value. When R=1, the output is 0 and the pulses at input
Cnt are not counted.
If you set a Start Value the counter begins to count either up or down from this value.

Analog Analog threshold trigger
Description of the function:
The output is switched on when the analog
value exceeds a specified on threshold. The
output is switched off when the analog value
drops below a specified off threshold
(hysteresis).
This function reads the analog value AI1 to
AI8 as a value between 0 and 1000. The offset
parameter is then added to the analog value.The result is multiplied by the gain
parameter. Output Q is set to 1 if this value
exceeds the on threshold (On). Q is reset to 0
again after the value drops below the off
threshold (Off).

Analog PI controller
Description of the function:
If the input A/M is set to 0, then the special function sets
output AQ with the value that is set with parameter Mq.
If the input A/M is set to 1, then automatic mode
commences. As an integral sum the value Mq is
adopted, the controller function begins the calculations
of the formulas.
The updated value PV is used within the formulas.
Updated value PV = (PV * gain) + offsetIf the updated value PV = SP, then the function does not
change the value of AQ. With a disturbance, AQ
continues to increase / decrease until the updated value
PV again corresponds to SP. The speed with which AQ
changes depends on the parameters KC and TI. If the
input PV exceeds the parameter Max, then the updated
value PV is set to the value of Max. If the PV falls short
of the parameter Min, then the updated value PV is set
to the value of Min. If the input R is set to 1, then the AQ
output is reset. As long as R is set, the input A/M is
disabled. The sampling time is fixed at 500 ms.

Analog Ramp
Description of the function:
At the analog output, this special function starts up one of two
levels or offset. Here you can set how quickly the level should
be reached. If the input En is set, then the function issues the
value StSp + offset at output AQ for the first 100 ms.
Then, depending on the connection of Sel, the function runs
from value StSp + offset to either level 1 or level 2 at the
acceleration set in Rate.
If the input St is set, the function runs to the value StSp + offsetat the acceleration set in Rate. Then the function issues the
value StSp + offset at output AQ for 100 ms. Finally offset is
issued at output AQ.
If the input St is set, the function can only be restarted once the
inputs St and En have been reset.
If input Sel has been changed, depending on the connection of
Sel, the function runs from level 1 to level 2 or the other way
round. If the input En is reset, the function immediately issues
offset at output AQ. The analog value at the output is
recalculated every 100 ms.

Analog Pulse Width Modulator (PWM)
Description of the function:
The PWM function modulates the analog input
value Ax into a pulsed digital output signal. The
pulse width is proportional to the analog value Ax.
The function reads the value of the signal at the
analog input Ax. This value is multiplied by the
value of parameter A (gain). Parameter B (offset) is
added to the product, as follows:
(Ax * Gain) + Offset = Actual value Ax
The function block calculates the proportion of the
value Ax to the range. The block sets the digital
output Q high for the same proportion of the PT
(periodic time) parameter, and sets Q low for the
remainder of the time period.

Analog Pulse Width Modulator (PWM)
Example 1:
Periodic time (PT) = 4 sec.
Ax = 500
1) 500 / (1000-0) = 0,5
2) 4 sec. * 0,5 = 2 sec.
Q = 2 sec. high , 2 sec. low
Example 2:
Periodic time (PT) = 10 sec.
Ax = 300
1) 300 / (1000-0) = 0,3
2) 10 sec. * 0,3 = 3 sec.
Q = 3 sec. high , 7 sec. low
Calculation rule :
Q = 1, for Ax / (Max - Min) of time period PT
Q = 0, for PT - [Ax / (Max - Min)] of time period PT
Note: Ax in this calculation refers to the actual value Ax as calculated using the Gain and Offset.
Min and Max refer to the minimum and maximum values specifed for the range.

Description of the function:
The function combines four values
and three operators to form an
equation. The operator can be any
one of the four standard operators:
+ , - , x ,/
For each operator, you must set a
unique priority of High ("H"), Medium("M"), or Low ("L").
The high operation will be performed
first, followed by the medium
operation and the low operation. The
operand values can reference
another previously-defined function
to provide the value.
You can also configure the behavior
of the function when the Enable
parameter "En"=0.
The function block can either retain
its last value or be set to 0.
The result is an internal analog value
(-32768 - +32767). A result out of
this range causes an overflow-error.

Let us have a look at our example:
When switch S1 is closed, input I1 is supplied with voltage and the status at input I1 is 1.
LOGO! program calculates the status for the outputs.
Output Q1 is 1, in this case.
When Q1 is 1, LOGO! sets relay Q1, and the load connected to Q1 is supplied with
voltage.
The window to the left displays time and date.
The window in the middle displays the inputs
states (I1 to I9; I10 to I19; I20 to I24).
The window to the right displays outputs
states (Q1 to Q9; Q10 to Q16).
Also the internal values of all analoginputs/outputs can be displayed.

Step 12: Program testing
An excellent tool is available for program testing.
This tool
has to be selected when
you want to test the
program. With the
activation of the offline
simulation a tool bar for
monitoring and operation
of inputs and outputs is
selected. A plug symbol
provides a simulation of
power failure to test the
behavior in regards to
retentivity.
By clicking on the
buttons on the tool
bar or on the inputs in
the circuit diagram
you can change the
status of the inputs.
The signal run can be
tracked with the color
change from blue (lowsignal) to red (high
signal) of the
connection lines. This
makes error tracking a
lot easier.

Step 12: Program testing
As an additional program testing feature, each input can be allocated to a certain switchfunction.
Each input of a block can be allocated to a certain switch function via the context menu
(right mouse key) of an input block. You can chose between pushbutton (n.o. contacts, n.c.
contacts), switches and frequency inputs at digital inputs. With frequency inputs the
simulated frequency can be adjusted in Hz. With analog inputs the value range and the start
value is preset. These parameters can centrally be changed and reviewed as well via the
menu item Tools-> Simulat ion parameters.

This password protects your program only on LOGO!. There you can not delete, change or
view it without the password! To load a password protected program onto a PC, the
password is necessary as well. To delete an assigned password, enter Old passwordandleave New Passwordempty.
To be able to reuse a LOGO! with program and password when password is lost, the
password has to be entered incorrectly three times at program deletion. Then the program
and the PW is automatically deleted. This can alternatively be done by software. *)
