TRICONEX T8231 英维思 

TRICONEX T8231可编程序逻辑控制器（可编程逻辑控制器(Programmable Logic Controller))或者可编程序控制器是一个工业计算机那已经是加固并且适于控制制造过程，例如装配线机器，机器人的设备或任何需要高可靠性、易于编程和过程故障诊断的活动。迪克·莫利被认为是PLC之父，因为他发明了第一台PLC，Modicon 084，用于通用汽车1968年。

TRICONEX T8231的范围从小型模块化设备到数十个输入和输出(I/O)在与处理器集成的外壳中，到具有数千个I/O的大型机架安装的模块化设备，并且通常与其他PLC和监控和数据采集（supervisory control and data acquisition的缩写）系统。[1]

它们可以设计用于多种数字和模拟I/O配置、扩展的温度范围、抗扰度电气噪声、以及对振动和冲击的抵抗力。控制机器运行的程序通常存储在电池备份或非易失性存储器。

PLC最初是在汽车制造业中开发的，以提供灵活、坚固和易于编程的控制器来代替硬连线继电器逻辑系统。从那以后，它们作为适用于恶劣环境的高可靠性自动化控制器被广泛采用。

TRICONEX T8231就是一个例子硬实时系统，因为输出结果必须在有限的时间内响应输入条件而产生，否则将导致非预期的操作。

The TRICONEX T8231 Programmable Logic Controller (Programmable Logic Controller) or programmable logic controller is an industrial computer that has been hardened and adapted to control manufacturing processes, such as assembly line machines. Robotic equipment or any activity that requires high reliability, ease of programming and process fault diagnosis. Dick Morley is considered the father of the PLC because he invented the first PLC, the Modicon 084, used by General Motors in 1968.

The TRICONEX T8231 ranges from small modular devices to dozens of input and output (I/O) in processor-integrated enclosures to large rack-mounted modular devices with thousands of I/ OS. and often with other PLCS and supervisory control and data acquisition (short for Supervisory Control and Data Acquisition) systems. [1]

They can be designed for multiple digital and analog I/O configurations, extended temperature ranges, immunity to electrical noise, and resistance to vibration and shock. The programs that control the operation of the machine are usually stored in battery backup or non-volatile memory.

PLCS were originally developed in the automotive manufacturing industry to provide flexible, robust, and easily programmable controllers in place of hard-wired relay logic systems. Since then, they have been widely adopted as highly reliable automation controllers for harsh environments.

The TRICONEX T8231 is an example of a hard real-time system, because the output result must be produced in response to an input condition within a limited amount of time, otherwise it will result in unexpected operations.
