SCHNEIDER140CPU31110由于DCS将系统控制功能分散在各台计算机上实现，系统结构采用容错设计，因此某一台计算机出现的故障不会导致系统其它功能的丧失。此外，由于系统中各台计算机所承担的任务比较单一，可以针对需要实现的功能采用具有特定结构和软件的计算机，从而使系统中每合计算机的可靠性也得到提高。开放性DCS采用开放式、标准化、模块化和系列化设计，系统中各台计算机采用局域网方式通信，实现信息传输，当需要改变或扩充系统功能时，可将新增计算机方便地连入系统通信网络或从网络中卸下，几乎不影响系统其他计算机的工作。

SCHNEIDER140CPU31110 Due to the DCS’s decentralized implementation of system control functions on various computers, the system structure adopts a fault-tolerant design, so the failure of one computer will not lead to the loss of other system functions. In addition, due to the relatively single task undertaken by each computer in the system, computers with specific structures and software can be used for the functions that need to be implemented, thereby improving the reliability of each computer in the system. Open DCS adopts an open, standardized, modular, and serialized design. Each computer in the system communicates through a local area network to achieve information transmission. When it is necessary to change or expand system functions, the newly added computers can be easily connected to or removed from the system communication network, almost without affecting the work of other computers in the system.

Flexibility is achieved through configuration software to configure software and hardware based on different process application objects, including determining measurement and control signals and their interconnection relationships, selecting applicable control laws from the control algorithm library, and calling basic graphics from the graphics library to form various monitoring and alarm screens required, thus facilitating the formation of the required control system. The SCHNEIDER 140CPU31110 controller module is easy to maintain small or micro computers with a single function, and has the characteristics of simple and convenient maintenance. When a certain part or computer malfunctions, it can be replaced online without affecting the entire system operation, quickly eliminating faults.
