A 100m network using 4 cores is sufficient, and the application of Profinet network only supports 100m.

Anonymous users2024-02-14Can not see. In fact, whether it is 4 cores or 8 cores, in fact, the knowledge we use is only two lines. I don't know if it's related to the 2nd floor, but it's also related to the transmission speed.

Anonymous users2024-02-12I think the 4-core Siemens network cable has nothing to do with the cost, the industrial control network cable used by Siemens is made of single crystal, the purity is very high, the transmission speed is higher than that of the ordinary 4-core network cable, which is mainly used for system connection, and the difference between the industrial control network cable and the ordinary network cable is: the industrial control network cable is stable and reliable, and the data transmission can not be interrupted for a few tenths of a millisecond. A few milliseconds of data interruption can cause a running machine to crash.
Ordinary Internet access is about speed, and the stability requirements are not so high, just like if you are playing a game, no matter how fast the Internet speed is stuck, it feels normal, and it will not cause much consequence. A 30 cm network cable Siemens imports sell more than 100 cores, do you think 4 cores is still a cost problem? Don't consider the cost of industrial control things.

Anonymous users2024-02-111. The standard network cable is 8 cores, but the general use is to use 4 cores inside. In order to reduce costs, some network cables now only make 4 cores, which is the same in our ordinary use.
2. If in some special occasions, the 4-core network cable will not work. For example, the gigabit network cable must be 8 cores, and when the passive AP uses PoE to provide power supply, it must also use 8 core network cables.

Anonymous users2024-02-10No, it seems that Siemens' Profinet connector can only use a four-core cable.

Anonymous users2024-02-09I haven't used 4 cores, I have always used 8 cores, does Siemens also have special products for Ethernet cables?

Anonymous users2024-02-08Hello, dear <>
The square number of Siemens' 8-core network cable and 4-core spine network cable is not the same. Siemens 8-core network cable is a commonly used network communication cable, which is composed of 8 conductors (4 pairs). Each pair of wires is used to transmit different signals, such as data transmission, power supply**, etc.
It is suitable for high-speed data transmission and network communication. On the other hand, a 4-core network cable has only 4 wires and is usually used for low-speed data transmission or power supply only. It is suitable for some simple network connections, such as ** lines, sensor signal transmission, etc.
Due to the number of wires and the purpose of use, the square number of Siemens 8-core and 4-core cables is also different. An 8-core cable has a square number of 64, while a 4-core cable has a square number of 16. This means that the number of connection points for an 8-core network cable is 64, and the number of connection points for a 4-core network cable is 16.
Therefore, there are obvious differences between Siemens 8-core and 4-core network cables in terms of wiring specifications, signal transmission capabilities and application ranges. Users need to select the appropriate network cable type according to specific application requirements. <>
The main difference between fb and fc is that fc uses a shared data block, fb uses a background data block, fb uses a background data block, for example, if you want to control 3 motors with the same parameters, then you only need to use fb programming plus 3 background data blocks, but if you use fc, then you need to constantly modify the shared data block, otherwise it will lead to data loss. FB ensures that the parameters of the 3 motors do not interfere with each other. >>>More

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
