PH-II Simple Application Controllers
Key, System Bit and Function Block Lists 9
ENG-46
Speed Detect
SPD
25
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.
Pulse Width
Modulation
PWM
16
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.
Retentive
Alternate
RAL
13
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 PH-II
series is placed in the Stop mode.
Addition
ADD
20
y = A + B
Subtraction
SUB
20
y = A - B
Multiplication
MUL
20
y = A
´
B
Division
DIV
20
A
¸
B = q, r (quotient and remainder)
Calculation
CAL
*4
Equation using
+
,
-
,
´
,
¸, %
and the selected data.
Shift
SFT
19
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.
GSM SMS
SMS
*5
The contents of an LCD screen is sent as an SMS
message.
Random One
Shot
ROS
19
The random length single pulse is output.
Delayed One
Shot
DOS
20
After a delay time, send a single pulse
Delayed
Alternate
DAL
16
After a delay time, output alternates turning ON or OFF
with each input pulse
Retentive
Set/Reset
RSR
14
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
PH-II series is placed in the Stop mode.
Control
Display
CDP
*6
Control which Display screen appears on the LCD.
This function block can only be set in the
Pharao Software 2.0.
When control bit N04 is ON, it possible to control the
displayed User Screen.
Connect
_B
10
This CONNECT function block is an internal FB used
to show the memory used by the system bits and the
operation keys. No function block appears on screen
or shows as being used in the “Memory Configuration
Usage” dialog box, the purpose is only to calculate the
memory that is used by the bits listed above.
