Timer On-delay

Description of the function:

With 0 to 1 transition of input Trg the timer starts. If the status of input Trg is 1 for long

enough, the output is set to 1 on expiration of the time T. The output follows the input with

on delay. The output is reset to 0 when the status at input Trg is 0.

If the status of input Trg changes to 0 before the time T has expired, the time is reset. The

time elapsed is reset after a power failure.

A look at the circuit diagram shows that the motor only starts after

expiry of the delay time.

This function is called On-delay.

In words the motor will be switch on with a programmed ON delay

time.

When the input Trg is 1, the output Q is switched instantaneously to 1. When the status of

Trg changes from 1 to 0, the timer will be activated. The output remains set. When the timer

reaches the configured value (Ta=T), output Q is reset to 0. When input Trg is switched on

and off again, the time Ta restarts. Input R (Reset) is used to reset the time Ta and the

output before Ta has expired.

Timer Off-delay

A look at the circuit diagram shows that the motor only stops afterexpiry of the delay time.

This function is called Off-delay.

In words the motor will be switch off with a programmed OFF delay

time.

This function is called On-/Off-delay. In words the motor isswitched on and off with a programmed delay time.



The time TH starts after a 0 to 1 transition at input Trg. If the status at input Trg is 1 for the

duration of the time TH, the output is set to 1 on expiration of the time TH.

(the output follows the input on delayed). When the status at input returns to 0, TL starts. If

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.


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


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


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


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.

This special function outputs one of four predefined analog values or 0 at the analog

output. If input En is set, then the function issues one of 4 possible analog values V1 to V4

at output AQ, depending on the value of S1 and S2. If the input En is not set, then the

function issues the analog value 0 at output AQ. All 4 analog values V1 to V4 can be

parameterized as a reference to another analog function, so the analog values can be

dynamically changed in runtime (e.g. via potentiometer at an analog input).Integrated

Analog Pulse Width Modulator (PWM)


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.

Integrated

functions


52/146

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.

Analog - Analog Math


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.

The analog math error detection block sets the output when the referenced analog math

function block has an error. You can program the function to set the output on a zero

division error, an overflow error, or when either type of error occurs.

If you select the Automatically reset checkbox, the output is reset prior to the next

execution of the function block. If not, the output retains its state until the analog math error

detection block is reset with the R parameter.

Due to the split-up of the program across several pages, connection lines might have to beseparated.

Connections can easily be separated by selecting the scissor symbol. The interfaces are

clearly labeled with the page number, block number and input pin. Clicking a second time

with the scissor symbol on one of the interface placeholders undoes the separation.

Step 12: Program testing


123/146


After configuration and documentation, program testing via offline simulation is the nextstep.

Now you know that the program can be run in LOGO!, but you still have to check whether

your program works the way you intended it. Perhaps you would like to change some

parameters. You can effortlessly change input values, check the behavior upon power

failure and compare your calculations or expectations with the real behavior of the outputs.

LOGO! Soft

Comfort V6.1



124/146


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.

LOGO! Soft

Comfort V6.1

For time-critical simulations you can also set

the output of a block (forcing), by clicking theoutput with the right mouse button.



125/146


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.

Step 13: Assign program password


126/146

Step 13: Assign program password

To protect the program and your know how you can place a valid up to 10-digit passwordfor that program.

LOGO! Soft

Comfort V6.1

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. *)
