Hour
Meter
[HM]
The Hour Meter Function Block holds the
output status ON for a maximum of 32767
hours, 59 minutes and 59 seconds. If the
input pin is turned OFF the elapsed time
will hold its value until either the clear pin
resets the time or the input pin is turned ON
again.

Speed
Detect
[SPD]
The Speed Detect Function Block is used to
count the incoming pulses max. 20Hz (with
an extension module max. of 1kHz) for a
set period of time. The upper and lower lim-
its can be set from -32768 to +32767 and
the Period interval’s set range is 1 to 32767
in 10ms increments.

PWM
[PWM]
The Pulse Width Modulation Function Block
changes the output status according to a
set period of time with a minimum of 100ms
and a maximum of 3276700ms in
increments of 100ms. The percentage duty
for the function controls the amount of
elapsed time before the output status is
changed.

PID
[PID]
The PID Function Block is the AL2
implementation of PID, a method used to
obtain stable control over a system variable.
It is equipped with an Auto-tuning function,
which automatically adjusts the Function
Block parameters for the specific applica-
tion.

Retentive
Alternate
[RAL]
The Alternate Function Block is used to
reverse the ON and OFF state of the output
as and when the input pin receives a signal.
The output will be set ON when the input
pin goes high and remain ON until the input
receives the second rising edge. When the
power is turned OFF the function block will
use the last alternation operation to control
the output.
