This document provides information about PLC FATEK (FBs-40MAT) including descriptions of its digital input and output circuits, LED indicators, communication ports, input and output status indicators, and how to create and test a sample ladder logic program using WinProladder software. It describes how to input and annotate a sample program testing inputs X0 and X1 to control output Y0 using a T0 timer, save the program to the PLC, run and debug the program simulation, and monitor I/O status.

(FBs-40MAT)

4. Digital Input (DI) Circuit
The single-end input circuit can be set to SINK or
SOURCE type by varying the wiring of the common
terminals S/S inside PLC and external common wire of
input circuits.
 24VDC Single-End Input Circuit

5.  Digital Output (DO) Circuit
 Single-End Output Circuit
There are three kinds of output device for the single-
end output, which are relays, TRIAC and transistors.
Since the relay and TRIAC are bilateral, even when
used in single-end output, they can serve as SINK or
SOURCE output.
The transistor its SINK and SOURCE polarities are
exactly the opposite (common point Cn of SINK
output must connect to negative end of DC power).
the product model of transistor output of FBS-PLC
for SINK and SOURCE is distinct.

6. (common point Cn of SINK output must connect to negative end of DC power)

7. (common point Cn of SOURCE output must connect to positive end of DC power)

8. LED Indicators on PLC Main Unit
and Troubleshooting

9.  Power Indicator "POW〞
After the PLC is power on, with correct power
source and wiring, the〝POW〞LED indicator in
the middle of the PLC nameplate will turn on,
indicating that power supply is normal.
 Operation Indicator "RUN〞
As long as the CPU is working properly, in the
STOP state, this indicator will go on and off for 2
seconds, respectively.
When it’s in the RUN state, the indicator will go on
and off for 0.25 seconds, respectively.

10.  Error Indicator "ERR〞
In normal PLC operation, either in RUN or STOP
state, this indicator will not show any signal (off).
If it is on, it means that the system has an error
(e.g., WDT time-out, program error,
communication error, etc.)
If it is constantly on, please reset the power.
When the ERR indicator flashes with a 0.5 sec
interval, it means that some anomaly occurs to
PLC. At the same time, status indicators Y0~Y3
switch to serve as indications of 15 error codes
(the corresponding outputs are disabled), which
are described in the following：

12.  Indicator on Transmit/Receive of Built-In
Communication Port (Port0) “TX”、“RX”
The RX indicator (green) is for indication when PLC
receives external signals, while the TX indicator
(red) is for indication when PLC transmits signals.
 Indicator of Input Status〝Xn〞
When external input Xn is ON, the corresponding
LED indicator Xn will be on, otherwise it will be off.
 Indicator of Output Status〝Yn〞
When the Yn output of PLC is ON, its corresponding
output indicator will also be on and its external load
will be ON.

Software
Step 1: Execute the WinProlad.exe program .
Step 2: Select [File] [New Project] from the function
toolbar using your mouse, or press “Ctrl” + “N” on your
keyboard, and the [New Project] window will appear
Step 3: Enter “Test example” into the [Project Name]
field.
Step 4: Click on the Edit button to enter the PLC
model type selection screen.
 Create a Project

16. Step 5: Select the corresponding
model type according to the actual
testing machine.

17. Step 6: Click the OK button, and the following
screen will appear:

20.  Input and Edit the Example Program
Using Your Mouse to Input and Edit the
Example Program
Step 1: first move your cursor to the upper left
hand corner of the ladder diagram window and
click on it, you should then see a flashing blue
square at that same location.
Step 2: Move your cursor to where the
component tray is, there should be an icon
that looks like the following:

21. Step 3: Left click on the button and a A normal
open contact cursor should appear, move this
cursor to the location of the blue square and
perform a left click. The following dialog window
should appear:
Step 4: Input “X0” and then press “Enter” to input
X0 with a normal open contact.

22. Step 5: Input “X1” using the same method as the X0
normal open contact.
Step 6: Left click on the button and a coil cursor
should appear, move this cursor to the location of
the blue square and perform a left click. The
following dialog window should appear:
Step 7: Input “Y0” and then press “Enter” to
input Y0 with a coil.

23. Step 8: Move your mouse cursor to the in the
component tray and click on it, a cursor with a vertical
short circuit icon should appear, move it at specified
location.
Step 9: Input “Y0” using the same method as the
X1 normal open contact and put it in parallel with
X1 open contact.
Step 10: Input the Y0 normal open contact in a new
network N001using the same method as the X0 .

24. Step 11: move your cursor to the in the component
tray and click on it, now a cursor in the shape of a T
should appear. Left click on your mouse and the
following dialog box window should appear.
Step 12: After you input “0”, use your mouse or the
“Down” arrow key to move the cursor to the [PV] field
and input “100” and then press “Enter” or click on the
“OK” button using your mouse , now you have
completed the input of the T0 timer function.

 Enter Simulation Mode
Main Menu: PLC > Simulation
It will enter into the simulation mode after execution.
 Start Execution of Program Simulation
Main Menu: PLC > Run
After execution, the color of power line of ladder
program will become to red color as the screen
shown as below:

40. During the execution, there is a blinking red dot at the
left side of status bar. On the right of the red
dot has SC:xx, xx means the number of time have
been scanned.
 Pause of Program Simulation

”single scan”
After set this mode, you can use
space bar or Main menu: PLC
>Resume Simulation to start a
new scanning work.

42.  Multiple Scan
Main menu: PLC > Setup Simulation choose
“multiple scan”
After selecting the mode, you can set number of
scans to be performed in the number of scanning
field.
When the scan has reached
the set number, it will pause
the scanning.

43.  Stop Simulation
Main menu: PLC > Stop
Simulate the PLC “stop” operation, when next time
