5SHY4045L0006 ABB 可编程逻辑控制器梯形逻辑广泛应用于工业环境中，用于编程需要对制造过程和操作进行顺序控制的PLC。这种编程语言对于编程简单而关键的系统或者将旧的硬连线系统改造成新的可编程系统非常有用。这种编程语言也大量用于高度复杂的自动化系统，如电子和汽车工厂。 梯形逻辑背后的想法是，即使没有编程背景的人员也可以快速编程，因为它利用常规和熟悉的工程符号进行编程。但是这种优势很快就被否定了，因为PLC的制造商通常也为他们的产品提供梯形逻辑编程系统，这些系统有时不使用与其他制造商的其他型号的PLC相同的符号和约定；事实上，编程系统通常只适用于特定的型号，所以程序不容易移植到其他PLC型号上，或者必须彻底重写。

5SHY4045L0006 ABB Programmable Logic Controller is a power semiconductor switching device (integrated gate commutated thyristor = gate commutated thyristor + gate unit) developed by medium voltage inverter for use in large power electronics packages.
It was proposed by ABB in 1997. IGCT has made great progress in power, reliability, switching speed, efficiency, cost, weight and volume, and has brought a new leap to power electronic complete sets.
IGCT integrates the GTO chip with the anti-parallel diode and gate driver circuit, and then connects it with the gate driver in a low inductance mode at the periphery, combining the stable turn-off ability of the transistor and the advantages of the low on-state loss of the thyristor
The performance of thyristor is displayed in the on-stage, and the characteristics of transistor are displayed in the off-stage. IGCT has the characteristics of large current, high blocking voltage, high switching frequency, high reliability, compact structure, low on-off loss, etc., and it has low cost and high yield, so it has a good application prospect.

5SHY4045L0006 ABB Programmable Logic Controller Ladder logic is widely used in industrial environments for programming PLCS that require sequential control of manufacturing processes and operations. This programming language is useful for programming simple and critical systems or for retrofitting old hard-wired systems into new programmable systems. This programming language is also used extensively in highly complex automation systems, such as electronics and automotive factories. The idea behind ladder logic is that even people without a programming background can program quickly because it makes use of regular and familiar engineering notation to program. But this advantage was quickly negated because manufacturers of PLCS often also offered ladder logic programming systems for their products, which sometimes did not use the same symbols and conventions as other models of PLCS from other manufacturers; In fact, programming systems are usually only available for specific models, so programs are not easily ported to other PLC models, or must be completely rewritten.
