For example, if the encoder, running at 200 pulses per revolution, adopts A / Bx4 mode the FBs-PLC can achieve the same result that 800 pulses per revolution encoder can provide. 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. Each HHSC also has a clear and mask function. The highest counting frequency of a HHSC is 200KHz (MC) or 920KHz (MN).
FATEK MODBUS RTU EXAMPLE SOFTWARE
The FBs-PLC includes up to 4 sets of hardware high-speed counters (HHSC) and 4 sets of software high-speed counters (SHSC). Integrated high-speed counters with counting frequency up to 920 KHz If combined with the four sets of built-in HHSC, it can achieve a fully closed loop positioning control! One single unit has up to four axes outputs with a maximum frequency of 200KHz (MC) or 920KHz (MN) and equipped with multi-axis linear interpolation function. The NC position control adopts special positioning command language, which allows programming by mechanical or electrical units and the changing control of parameters during execution. 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. PLC & NC Control in one and Dedicated NC Positioning Language Each communication port comes standard with LED indicators for transmission (TX) and reception (RX) to enable the user to monitor the surgery. With their high speed and functionality the FBs-PLC has the greatest number of communication ports than any other PLC in its class. The FBs-PLC also provides the option of 8 different communication boards and 10 different communication modules for various types of communication applications. Along with FATEK’s standard protocol, Modbus ASCII / RTU / TCP or user-definable protocols are also available.
FATEK MODBUS RTU EXAMPLE CODE
Communications can be achieved using ASCII code or the double-speed binary code. Via the five high-speed communication ports included in the SoC, the FBsPLC’s communication capability is outstanding operating at a maximum speed of 921.6Kbps. 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. 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.
Also the operation result can be directly sent to internal or external outputs. With this multi-input instruction structure the user can derive many types of functionality which other brands of PLC’s may require the use of many instructions to achieve this. The FBs-PLC has more than 300 instructions which adopts a user friendly and readable multi-input / multi-output function structure. The FBsPLC represents high functionality and reliability with exceptional value compared to other PLC’s in its class.
The BGA chip consists of over 120,000 gates which integrates powerful features such as a Central Processing Unit (CPU), Memory, Hardware Logic Solver (HLS), 5 high-speed communication ports, 4 sets of hardware high-speed counters / timers, 4 axes of high-speed pulse outputs for NC positioning control (with linear interpolation), 16 high-speed interrupts and captured inputs. The FBs-PLC’s design incorporates a “System on Chip” (SoC) developed in-house by Fatek Corporation. FBs – Cutting Edge PLC SoC-FATEK’s Core Technology
