SCXI-1104C? 其內(nèi)部存儲(chǔ)執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算等操作的指令

可編程邏輯控制器（PLC）的工作原理基于一個(gè)程序循環(huán)，SCXI-1104C這個(gè)循環(huán)的步驟可以包括捕獲輸入信號(hào)，進(jìn)行邏輯運(yùn)算，生成輸出信號(hào)和等待一個(gè)周期的時(shí)間。在PLC的循環(huán)程序中，輸入信號(hào)被讀取并傳輸?shù)紺PU中，然后通過(guò)編程進(jìn)行邏輯運(yùn)算。這些邏輯運(yùn)算可以包括布爾運(yùn)算、算術(shù)運(yùn)算和比較運(yùn)算等等。根據(jù)編程的要求，PLC會(huì)生成輸出信號(hào)，并將它們發(fā)送到I / O模塊，然后控制外部的執(zhí)行設(shè)備。

當(dāng)可編程邏輯控制器投入運(yùn)行后，其工作過(guò)程一般分為三個(gè)階段，即輸入采樣、用戶程序執(zhí)行和輸出刷新三個(gè)階段。完成上述三個(gè)階段稱(chēng)作一個(gè)掃描周期。在整個(gè)運(yùn)行期間，SCXI-1104C可編程邏輯控制器的CPU以一定的掃描速度重復(fù)執(zhí)行上述三個(gè)階段。

可編程邏輯控制器（PLC）是一種專(zhuān)門(mén)為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)的數(shù)字運(yùn)算操作電子系統(tǒng)。SCXI-1104C采用一種可編程的存儲(chǔ)器，在其內(nèi)部存儲(chǔ)執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算等操作的指令，通過(guò)數(shù)字式或模擬式的輸入輸出來(lái)控制各種類(lèi)型的機(jī)械設(shè)備或生產(chǎn)過(guò)程。

從結(jié)構(gòu)上分，PLC分為整體式和組合式兩種。整體式PLC一般還配備有特殊的功能單元，如模擬量單元、位置控制單元等，使其功能得以擴(kuò)展。這類(lèi)PLC特點(diǎn)包括結(jié)構(gòu)緊湊、體積小、價(jià)格低，小型PLC一般采用這種整體式結(jié)構(gòu)。組合式PLC包括CPU模塊、1/O模塊、內(nèi)存、電源模塊、底板或機(jī)架，這些模塊可以按照一定規(guī)則組合配置。

The working principle of a programmable logic controller (PLC) is based on a program loop, SCXI-1104C, the steps of this loop can include capturing the input signal, performing logical operations, generating the output signal and waiting for a cycle time. In the PLC’s loop program, the input signal is read and transmitted to the CPU, which is then programmed to perform logical operations. These logical operations can include Boolean operations, arithmetic operations, comparison operations, and so on. According to the requirements of the programming, the PLC generates output signals and sends them to the I/O module, which then controls the external execution device.

When the programmable logic controller is put into operation, its working process is generally divided into three stages, namely, input sampling, user program execution and output refresh. Completing these three stages is called a scan cycle. During the entire run, the CPU of the SCXI-1104C programmable logic controller repeats the above three phases at a certain scanning speed.

A programmable logic controller (PLC) is a digital operational electronic system designed specifically for use in industrial environments. The SCXI-1104C uses a programmable memory in which the instructions for performing operations such as logical operations, sequence control, timing, counting and arithmetic operations are stored, and various types of mechanical equipment or production processes are controlled through digital or analog input and output.

In terms of structure, PLC is divided into integral and combined two types. Integral PLC is also generally equipped with special functional units, such as analog units, position control units, etc., so that its functions can be expanded. This type of PLC features include compact structure, small size, low price, small PLC generally adopt this integral structure. The combined PLC includes a CPU module, 1/O module, memory, power module, baseboard or rack, which can be combined and configured according to certain rules.
