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.

Counter – Up and Down counter
A look at the circuit diagram shows that the switch S1 triggers the counter pulses. Switch
S2 determines whether the counter increases or decreases. When the counter status
reaches 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.

Output Q is switched on, if the value measured within the gate time is higher than the ON
threshold. Q is switched off again when the threshold drops below OFF.
On : is the ON threshold. It may be between 0000 and 9999.
Off : is the OFF threshold. It may be between 0000 and 9999.

The result is multiplied by the gain

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) + offset
If 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

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 + offset
at 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)
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 - 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.

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 (low
signal) to red (high
