FBs - Series  Programmable Logic Controller  

Cutting edge in PLC  

State of the art technology  

Compact & Powerful  

Extensive product range  

Reliable & Durable  


SoC-FATEK's Core Technology  

The FBs-PLC's design incorporates a "System on Chips"(SoC) developed in-house by Fatek Corporation.  The chip consists of over 120,000 gates which integrates powerful features such as a Central Processing  Unit (CPU), Hardware Logic Solver (HLS), five high-speed communication ports, four sets of hardware  high-speed counters / timers, four axes of high-speed pulse outputs for NC positioning control (with linear  interpolation or dynamic tracking) 16 high-speed interrupts or captured inputs. The FBs represents high  functionality and reliability with exceptional value compared to other PLC's in its class.

User friendly and powerful instruction sets

The FBs-PLC has more than 300 instructions which adopts a user
friendly and readable multi-input/multi output function structure, with multi-input instruction structure can derive  many types of functionality which other brands of PLC's may require the use of many instructions to achieve this.Also the operation result can be directly sent to internal or external outputs.To increase the program readability, the inputs or outputs for each function instruction have their own mnemonic symbol attached and the content of each operand is also displayed. For high-end applications, such as PLC networking (LINK), PID control and NC positioning etc, the FBs-PLC provides dedicated convenient instructions to assist in program development.

Communication function (up to 5 ports including
RS232, RS485, USB, Ethernet and GSM)

Via the five high-speed communication ports included
in the SoC, the FBs-
PLC's communication capability is outstanding with all five ports operating
at a maximum speed of 921.6Kbps. Communications can be 
using ASCII code or the double-speed binary code. Along with FATEK's standard protocol, Modbus ASCII/RTU/TCP or user-definable protocol are also available. The FBs.-PLC also provides the option of six different communication boards and eight different communication modules forvarious types of communication applications. With their high speed and
functionality the FBs-PLC has the greatest number of communication ports than any other PLC in its class. Each communication port comes standard with LED indicators for transmission (TX) and reception (RX) to enable the user to monitor the operation. 

Up to 4 sets of high-speed pulse width
(HSPWM) output

The SoC inside the FBs-PLC incorporates four sets of hardware high-speed pulse width modulation outputs with a maximum frequency of 184.32KHz and 18.432KHz with resolutions of 1% and 0.1%,
respectively. Different
from the PWM function operated by software alone in other brands of PLC, the hardware driven high-speed PWM in the FBs-PLC operates with high precision and stability which provides the user easy control with precise accuracy.


PLC & NC Control in one and Dedicated NC Positioning Language

NC Position Control is incorporated into the SoC of the FBs-PLC which integrates PLC+NC control into one unit in order for resources sharing and reducing the need of data exchange. The NC position control adopts special positioning command language, which allows programming by mechanical or  electrical  units  and  changing  control  parameters  during  execution. One single unit has up to four axes outputs with a maximum frequency of  200KHz  (MC)  or  920KHz  (MN)  and  equipped  with  multi-axial  linear interpolation and dynamic tracking. If combined with the four sets of built-in HHSC, it can achieve positioning control with closed loop precision.


Integrated high-speed counters with counting frequency up
to 920 KHz

The FBs-PLC as standard has up to 4 sets of hardware high-speed counters (HHSC) and 4 sets of software high-speed counters (SHSC). The highest counting frequency of a HHSC is 200KHz (MC) or 920KHz (MN).Each HHSC also has a clear and mask function. There are 8 counting modes including U/D, U/Dx2, P/R, P/Rx2, A/B, A/Bx2, A/Bx3 and A/Bx4 which makes the HHSC very powerful and efficient. For example, if the encoder, running at 200 pulses per revolution, adopts A/Bx4 mode the FBs-PLC can achieve the same result that a 800 pulses per revolution encoder can provide. The counter is implemented in the hardware so as not to occupy CPU processing time.


High-speed timers (HST)

The FBs-PLC is the only PLC in this class providing 0.1mS high-speed timers (the FBs-PLC having one 16-bit and 4 sets of 32-bit HST). Currently, the fastest time base of high speed timers used in other brands of PLC's is 1mS. By incorporating the interrupt function of the FBs-PLC the accuracy of 0.1mS time base high-speed timer of FBs-PLC is further enhanced and can easily achieve more precise speed detection or can be used as a frequency meter. In most cases, expensive speed detection equipment can be replaced by the economical FBs-PLC.

FATEK's Powerful Communication Features

The five communication ports in FBs-PLC can simultaneously connect to various intelligent peripherals with available interfaces such as USB, RS232, RS485 and Ethernet. Besides adopting  FATEK  standard  communication  protocol  or  Modbus  protocol  or  conducting communication through the FATEK communication server, the user also can use CLINK commands to define the dedicated protocol to actively or passively establish the connection with any intelligent peripherals.

Single unit with 16 points of high-speed interrupt

The FBs-PLC provides 16 points of external interrupts. The interrupt is edge driven and the user can define which edge triggers the interrupt and can be positive, negative or both edges. The interrupts can perform high speed, emergency processing which can withstand the time jilter caused by the delay and deviation of the scan time and can be used for precision high speed positioning, machine home and high speed RPM measurement applications.

 Up to 36 points of captured input

The SoC in the FBs-PLC has a capture input function, which captures and stores the external pulse of an input shorter than the scanning time of the CPU. Compared to PLC's in this class that either lack this capability or require highly sophisticated interrupt functions (which increase the CPU processing time), the FBs-PLC can handle this task easily as a general input, easily configured with high efficiency and no detriment the CPU scan time.

 Complete range of peripherals

In  addition  to  the  204  models  of  main  CPU  units,  the  FBs-PLC  also provides 65 models of expansion I/O for selection. The expansion I/O modules include basic DI/O and AI/O, 7/16-segment LED display module, 8 types (J,K,R,S,E,T,B,N) thermocouple, Pt100, Pt1000 RTD temperature measurement modules. The FBs-PLC also provides a FBs-DAP LCD data access panel which can be linked together with a single RS485 bus. The FBs-DAP can be a simple Timer/Counter editor or it can also be used as a simple human machine interface through the function of user definable keys and message display. The FBs-DAP can be equipped with a wireless RFID sensing module and can be applied to such applications as entrance control, parking equipment and elevator control amongst others.

 Open communication driver

The  open  communication  protocol  of  the  FBs-PLC  is  supported by  all  major  brands  of  graphic  supervisory  software  (SCADA)  and leading  brands  of  Human-Machine  Interfaces  (HMI)  and  can  be directly connected with the FBs-PLC via serial and Ethernet interface. FATEK  also  provides  Modbus  protocol  and  FATEK  DDE  standard communication server or third-party OPC server for the user to easily connect the FBs-PLC to various control or supervisory systems.

 User-friendly operating environment

 "WinProladder" is the Windows-based ladder diagram programming software  for  the  FBs-PLC.  It  provides  a  user-friendly  operating environment with editing, monitoring and debugging functions which allows the user to become familiar with the operation of the software in a very short time. The powerful editing function of WinProladder, assisted with keyboard, mouse and on-line help (of ladder instructions and operating guide) greatly reduces programming development time. Features which can displays the data registers directly in the ladder diagram and provide multiple status pages for monitoring gives the user the ability to monitor and debug easily.
