This article introduces the advanced applications of FBs-PLC, including interrupts, high-speed counters and timers, and communication functions. By explaining in detail the principles and architecture of interrupts, the structure and application of interrupt service programs, the label names and priorities of interrupt components, and how to use interrupts, it helps users understand and use the interrupt function. At the same time, it introduces the system structure, usage steps, and application examples of high-speed counters and timers of FBs-PLC, as well as the functions and applications of communication ports, hardware wiring considerations, and software interface types. With the guidance of this article, users can better master and apply the advanced functions of FBs-PLC.
This manual covers the advanced features of the FBs‑PLC, starting with interrupt architecture, service program structure, component naming, priority handling and configuration examples using FP‑07C, WinProladder and R4162. It also details the high‑speed counter and timer system, including single‑phase and dual‑phase modes, configuration steps and application examples.
Further chapters describe the PLC's communication ports (USB, RS‑232, RS‑485, Ethernet), LINK functions (MODBUS, CLINK), NC positioning control, ASCII file output, real‑time clock, 7‑segment LED display module, various analog input/output modules, temperature measurement modules (TC and RTD), and both generic and dedicated PID control instructions with sample programs. Appendices provide instruction overviews and protocol details. This manual is written in Chinese.

The manual provides a step‑by‑step example in section 9.5.1 titled “用 FP-07C 作〝外部中断〞的建构范例”.
Section 10.3 outlines the usage steps for the high‑speed counter, including mode selection and configuration procedures.
