The FBs-PLC’s design incorporates a “System on Chip” (SoC) developed in-house by Fatek Corporation. 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 FBsPLC represents high functionality and reliability with exceptional value compared to other PLC’s in its class.
The FBs-PLC has more than 300 instructions which adopts a user friendly and readable multi-input/multi-output function structure. 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. 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, CANopen® and GSM and ZigBee™ wireless communication). 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. 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 protocols are also available. The FBs-PLC also provides the option of 8 different communication boards and 10 different communication modules for various 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.
