Description
The signal input frequency (On/Off) is measured for a
set length of time. The frequency is compared to a
value range and the Output is turned ON/OFF
according to the result.
A continuous pulse train is output when this function
block is driven. The characteristics of the pulse are
defined as; Pulse duty (Direct set, Analog, FB values),
cycle time.
Output alternates turning ON or OFF with each input
pulse. The last output status is kept when the power
supply is cycled OFF and ON.
However, last output status is lost when the
is placed in the Stop mode.
y = A + B
y = A - B
y = A × B
A ÷ B = q, r (quotient and remainder)
Equation using +, −, ×, ÷, % and the selected data.
Shift operation; When "SFT" signal is input, last "I"
signal status is output.
When using 8 bit shift operation, "Shift" function block
should be continued 8 times.
The contents of an LCD screen is sent as an SMS
message.
The random length single pulse is output.
After a delay time, send a single pulse
After a delay time, output alternates turning ON or OFF
with each input pulse
Latch a relay in SET or RESET position, give Set or
Reset priority. The last output status is kept when the
power supply is cycled OFF and ON.
However, last output status is lost when the
is placed in the Stop mode.
The PID Function Block is the
PID, a control method used to obtain stable control
over a system variable. It is a equipped with an Auto-
tuning function, which automatically adjusts the
Function Block parameters for the specific application.
The Analog Output function takes a digital value input
and delivers a corresponding analog voltage or current
to a selected channel on the AL2-2DA module.
