140CPU65260? 作為一種特殊的I/O單元

作為一種特殊的I/O單元，它仍具有I/O電路抗干擾、內(nèi)外電路隔離，與輸入輸出繼電器（或內(nèi)部繼電器，它也是PLC工作內(nèi)存的一個(gè)區(qū)?？勺x寫）交換信息等等特點(diǎn)。

這里的A/D中的A，多為電流，或電壓，也有為溫度。D/A中的A，多為電壓，或電流。電壓、電流變化范圍多為0～5V，0～10V，4～20mA。有的還可處理正負(fù)值的。

這里的D，小型機(jī)多為8位二進(jìn)制數(shù)，中、大型多為12位二進(jìn)制數(shù)。

A/D、D/A有單路，也有多路。多路占的輸入輸出繼電器多。

有了A/D、D/A單元，余下的處理都是數(shù)字量，這對(duì)有信息處理能力的PLC并不難。中、大型PLC處理能力更強(qiáng)，不僅可進(jìn)行數(shù)字的加、減、乘、除，還可開方，插值，還可進(jìn)行浮點(diǎn)運(yùn)算。有的還有PID指令，可對(duì)偏差制量進(jìn)行比例、微分、積分運(yùn)算，進(jìn)而產(chǎn)生相應(yīng)的輸出。計(jì)算機(jī)能算的它幾乎都能算。

140CPU65260? 作為一種特殊的I/O單元

As a special I/O unit, it still has I/O circuit anti-interference, internal and external circuit isolation, and input/output relay (or internal relay, it is also an area of the PLC operating memory. Readability) exchanging information and so on.

The A in A/D here is mostly current, or voltage, but also temperature. A in D/A is mostly voltage or current. The range of voltage and current is mostly 0 ~ 5V, 0 ~ 10V, 4 ~ 20mA. Some can also handle positive and negative values.

Here D, minicomputers are mostly 8-bit binary numbers, and medium and large machines are mostly 12-bit binary numbers.

A/D and D/A have either a single path or multiple paths. Multiple input/output relays.

With A/D and D/A units, the rest of the processing is a digital quantity, which is not difficult for a PLC with information processing capability. Medium and large PLC processing capacity is stronger, not only for the addition, subtraction, multiplication, division of numbers, but also for the root, interpolation, but also for floating point operations. Some also have PID instructions, which can carry out proportional, differential and integral operations on the deviation measure, and then produce the corresponding output. It can do almost anything a computer can do.
