How many host computers can there be?

There is now a Siemens 300 CPU. How many can be connected to his upper machine? Why are 5 machines connected through a switch? But some host computers cannot be connected at all. But a 400 one has no problem?
Answering the first question: There is currently a Siemens 300 CPU. How many can be connected to his upper machine? Answer: If using the 5611 card over Profibus, a large number of devices can be connected; the exact number depends on how many devices Profibus can support. But the 5611 card is very expensive, around 3000 yuan.
MPI: When using the CP5611 card on the host computer, up to 3 host computers can be connected; when using the CP5613 card, up to 5 host computers can be connected. PROFIBUS: With the CP5611 card on the host computer, up to 5 host computers can be connected; with the CP5613 card, up to 11 host computers can be connected. Ethernet: Using a regular network card on the host computer, up to 8 host computers can be connected; using the CP1613 card, up to 30 host computers can be connected. Moreover, it also depends on the model of your CPU.
It can’t be Manager Gong on the 3rd floor, right? Regarding the CPU specifically, in HW config->CPU properties there is an option called “Communication”; this allows you to see how many connections exist as well as to make settings accordingly
The original poster can create a server-client version; it’s easy to achieve this with WinCC
Use one computer as a server, and the others can be connected to N of them... where N is at least greater than 10; P
Below 317, there are generally 16 connection resources. 317 and above represent the number of 32 linked resources. Each CP343-1 module can be connected to a maximum of 8 S7 connections. (The total includes PLC–PC and PLC–PLC connections) Each CP343-1 lean module can be connected to a maximum of 4 S7 devices. 414-3 generally corresponds to 32 connection resources. 414-3 and above represent 64 connection resources. Each Cp443-1 module can connect up to 32 S7 connections. Another issue is that for connections involving more than 8 computers, it is highly recommended to use a C/S architecture. Whether it’s 300 or 400, that’s what it implies. It is highly not recommended to have more than 8 computers directly connected to each PLC!
