Why do you use get to communicate with touch screen? Is there no put?
Get is equivalent to PLC reading touch screen data, put is equivalent to writing data to touch screen.
1) Yes, only corresponding to the number of bytes, address inconsistency does not matter.
2) If you configure communication in this way, it is equivalent to reading two data areas. The local and remote addresses of the client and server do not need to correspond. If you just read the get touch screen data, you can press your address area without any problem.
The client needs to call net_ Exe command, the server touch screen side does not need, only need to set the communication IP address, the correct connection interface.
If the local CPU is connected to the remote CPU, can the parameters defined in the local CPU (vb1010-vb1012) be used on the touch screen connected to the remote CPU? Why?
: No, vb1010-vb1012 the address of area V called on the client computer of vb1010-vb1012.
Let's say that, suppose a button is pressed on the touch screen, and the address is v1000.0. If the communication connection is normal, when the touch screen address is v1000.0, the PLC will receive v1010.0 = 1
Similarly, if the touch screen has I / O data input address of vw1000, if the communication is normal, PLC will receive the input data from the touch screen in vw1010.
