I have to admit I have never pulled cable. However, similar laws apparently govern fishing line :-)  

From your description I am only assuming that your "new" CPU and touch are the same as the original.....it isn't exactly clear that this is definitely the case.  If they are identical, have you ensured that all firmware matches the version of the program being used?  Or go back to the original program and it's firmware? cheers, Aus

Hello, I probably have a problem with the USP-104-B10 touch panel. I bought a new CPU and touch  panel , installed the control program and the touch panel behaves very strangely. At the touch of a button, the panel does not react to the next screen. It starts to react sometimes when I touch the screen in four corners at the same time. Sometimes it reacts only after about 1 minute. Modbus communication ceases to operate periodically. The web server works properly, without delays. Variables on the touch panel screen are also displayed without delays. the same control program on the old panel worked properly (it was created on UNILOGIC software 1.19.83), a the same  control program converted to version 1.26.90). Now I have a big problem with it.

I'm not sure I understand. You want that HMI elements linked to some actions will sometimes perform the actions (if enabled), and sometimes, it will not?
