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 operatingat a maximum speed of 921.6Kbps. Communications can be achieved 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 modulation(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.
