Description: 虽然PLC广泛应用于工业控制中，PLC控制系统的程序依然和语法有关。和软件过程一样，PLC的软件设计也以同样的方式会遇到软件错误或危机。Morley在演讲中着重强调了这个方面。-Programmable Logic Controllers (PLC), a computing device invented by Richard E. Morley in 1968, have been widely used in industry including

Description: 虽然计算机控制技术已经产生，但是PLC控制因为它的高性能、成本低、并且对恶劣的环境有很强的适应能力而在工业控制的广泛应用中保持优势。而且，尽管硬件的价格在逐渐下跌，据估计，根据Frost和Sullivan对PLC市场的调查研究表明，每年销售硬件的价格要比销售PLC的价格（一千五百万）至少多出八十亿美元。PLC的创造者Richard E. Morley十分肯定的认为目前PLC市场是一个价值五十亿的工业-functional design. Programmable controller for the user, is a non-contact equipment, the procedures can be changed to change production processes. The programmable controller has become a powerful tool for factory automation, widely popular replication. Programmable controller is user-oriented industries dedicated control computer, with many distinctive features.

Description: 一般来说，和其他领域相比生产PLC的周期要短很多。例如，在实践中，VISI设计是一种有效的计算机辅助设计。PLC不需要使用目前的以软件设计为基础软件工程方法论，因为PLC程序要求对软件和硬件搜都要考虑到。因此，软件设计越来越成为花费动力。在许多的工业设计工程中，超过 的人力分配给了控制系统设计和安装，并且他们要对。PLC程序测试和排除错误，-In the mid-1970s, the Plc has been widely used as a central processing unit microprocessor, import export module and the external circuits are used, large-scale integrated circuits even when the Plc is no longer the only logical (IC) judgment functions also have data processing, PID conditioning and data communications functions. International Electro technical Commission (IEC) standards promulgated programmable controller for programmable controller draft made the following

Description: 如果房子建造的像软件过程一样，那么仅仅一只啄木鸟就可以摧毁文明。特别的，PLC程序要解决的实际问题是消除软件错误和减少老式梯形逻辑语言的花费。尽管PLC的硬件成本在继续下降，但是在工业控制上减少梯形逻辑的扫描时间仍然是一个问题，以至于可以用到低耗时的PLC。-Since it’s unlikely that an individual PLC would talk to broadband MAP anyway, makers are concentrating n proprietary networks. According to Sal Provanzano, users fear that if they do get on board and vendors withdraw from MAP, they ‘ll pulse width modulation control system be the ones left holding a communications structure that’s not supported.
