Issues with the variables of Zhejiang University Zhongkong JX-300X
Thread Content
I’m just starting to learn *Zhejiang University Zhongkong; I’ve never done anything like PLC programming before. 1. How is it achieved that, after performing addition, subtraction operations on a variable or making a judgment based on that variable, another value is changed? Is it implemented in graphical programming or SCX language programming? 2. Is the I/O card a functional module on the data forwarding card? What does the address in the I/O points mean?
These materials are available on SUPCON’s website at Zhejiang University Zhongkong
Using FBD is also possible; it includes addition modules and comparison modules, or ST’s IF statements – it’s similar to writing in C language. It is said that SCX will be discontinued in the future
Thank you to the person above; I finally understood one question. What about the second question? Is the I/O card a functional module on the data forwarding card? What does the address in the I/O points mean? Perhaps that person could send me a relatively complete version of the project for my reference. My email address is cw747@163.com. It doesn’t need to be very complex; just functional enough would be fine
2. Is the I/O card a functional module on the data forwarding card? What does the address in the I/O points mean? The data forwarding card serves as a bridge between the CPU and the I/O cards, as there is no direct way for the I/O cards to communicate with the CPU. Each card cage must consist of one data forwarding card (usually in a redundant configuration) along with several I/O cards
Just like the terminals, each station has N card cages, each card cage contains N cards, and each I/O card has multiple channels. To uniquely identify each channel, an address is required.
It’s similar to the IO of a PLC, I guess
Thank you to the two people above; haha, now that you’ve said it, I understand a bit better
