Anonymous users2024-02-06Take 6es7 221-0ba23-0xa0 as an example:
6ES --- automation system series.
7---7: S7 series, 5: S5 series.
2--- 2: 200 series, 3: 300 series, 4: 400 series.
2---1: CPU, 2: DI DO, 3: AI AO, 4: communication module, 5: function module.
1---1: Input, 2: Output, 3: Input-output (for digital), 4: Input-output (for analog).
0ba--- input and output voltage level, type, number of points, etc., this is more, or it is better to check the sample.
The 23--- version, if the last digit is different, can basically be universal.
0xa0--- is made in Germany.
0xa8--- is made in China.

Anonymous users2024-02-03When choosing Siemens PLC, you have to first consider what series of logos it is: low-profile PLC
200plc: Better than logo.
300PLC: Mainstream PLC
400PLC: Large PLC
If it is 300 400plc
1: You choose a power module first, there are 5A 2A select MCC card, 126 or 512 on one side is enough.
2: Choose a CPU again, this can only depend on the specific data, which is more suitable for you or directly ask the ** business.
3: There are also various signal modules i o analog modules These all depend on how much is needed for the specific project.

Anonymous users2024-02-02Siemens 300CPU does not have input and output, so you have to choose the IO module by yourself, some CPUs have DP function, if you need PROFIBUS
You can buy this CPU.

Hopefully...
Explanation: Two devices of the same model may have different programs. The same MMC card model only means that the hardware is the same, but the user program is not necessarily the same. >>>More
In 1867, German inventor Wenner von Siemens proposed major improvements to the generator. He argues that magnets are not used on generators (i.e., permanent magnets, but electromagnets. >>>More
It's very simple, you can buy it yourself, or you can create it yourself, or you can work it, don't think it's very simple, you can buy it yourself, or you can create it yourself, or you can work it, it's okay, don't think about getting it for nothing.

These two are mainstream PLCs, one made in Japan, one made in Germany, I have used both, both are very representative, it is recommended to learn both, you can learn Mitsubishi's first, because most of the programming methods of other brands of PLC are imitation of Mitsubishi, especially domestic brands, just like the Delta I use now, and Xinjie, which is almost exactly the same as Mitsubishi. Mitsubishi is what a traditional ladder looks like. And Siemens is also unique, although he also said that it is a ladder diagram, but his is a modular ladder diagram, which looks more intuitive than Mitsubishi's, and the step7 software is also very easy to use. >>>More
