中国科学院钍基熔盐核能系统固态燃料堆(Thorium-based Molten Salt Reactor-Solid Fuel, TMSR-SF)的控制系统设计采用 ABB 公司800XA 系列可编程逻辑控制器(Programmable Logic Controller, PLC)硬件。800XA系列的 PLC 虽然控制器和 I/O 模块丰富，但唯独缺少反应堆棒控棒位系统中关键的步进电机控制器模块。利用 ABB PLC 丰富的现场总线接口，将 AC500系列中的 CD522步进电机控制器应用到系统中，实现了800XA基于 Profibus-DP 即插即用的配置。组态过程中通过对控制器输入输出寄存器的灵活分配，不仅实现了控制器功能的定制，而且简化了后续函数库编程。编写了脉冲输出和编码器功能函数库，实现脉冲输出控制和编码器计数两个主要功能，并对棒控棒位系统的硬件结构进行了可靠性分析。组态好的控制器各项参数可满足棒控棒位系统的要求。

Background: The architecture of the control system for the solid fuel molten-salt reactor (TMSR-SF) is based on the ABB’s 800XA series programmable logic controller (PLC) hardware. The 800XA series PLC is widely used in the power industry due to its unique reliable design, but there is a lack of step motor controller which is the key component for control rod drive mechanism (CRDM). Purpose: This study aims to configurate a ABB AC500 step motor controller CD552 into the 800XA series PLCs to realize stepper motor driven pulse output and position detector inputs decoding. This is a key module for reactor Rod Control and Position Indicator (RCPI) system. Methods: The Proifbus-DP interface of the 800XA series PLCs is adopted to connect the step motor controller CD522 via its CDI 542 module. The plug and play (P&P) functionality of CD552 is achieved and optimized to work coherently based on Proifbus-DP. During the configuration of the controller, by a flexible input and output registers assignment, it not only achieves custom controller function, but also simplifies the subsequent library programming. Results: Two main functions of RCPI were implemented with a very low failure rate at the level of 8×10?6 by analyzing of the reliability of the hardware’s configuration based on CD522. Conclusion: Such kind of hardware configuration and software optimization can meet various performance parameters of the RCPI system, such as travel stroke, speed control required accuracy and position detection precision, etc.
