要评价开放控制的软件解决,需要熟悉各种软件PLC设计,IEC1131—3国际标准,软件DCS设计和故障容许或容错系统的软件设计方法。开放控制软件:软件PLC的设计软件PLC即应用软件使PC兼容的硬件能完成通用PLC的任务,这意味着在运行时PC成为一台专用的或通用的工业控制器,某些软PLC用在PC机上的协处理模板完成PLC的逻辑控制,同时PC主机可分享存储器中的实时数据,另一种软PLC形式为构造一实时操作系统环境,从而主PC专有一部分时间用于处理逻辑控制,而其余时间运行其他程序,包括操作员界面(OI)。
To evaluate open control software solutions, you need to be familiar with various software PLC design, IEC1131-3 international standards, software DCS design and fault tolerance or fault tolerant system software design methods. Open Control Software: Design Software for Software PLCs PLC-based applications enable PC-compatible hardware to perform the task of general-purpose PLCs, which means that the PC becomes a dedicated or general-purpose industrial controller during operation and some soft PLCs are used in The PC’s coprocessing template completes the logic control of the PLC while the PC host can share the real-time data in the memory. Another form of soft PLC is to construct a real-time operating system environment, so that the host PC is dedicated to processing logic control, While the rest of the time running other programs, including the operator interface (OI).
