Operation content: Establish communication between the touch screen and PLC to enable the touch screen to read and write PLC data

Communication method: Touch screen communicates with PLC through DP

Download line: USB/PPI

Precautions for operation:

Firstly, in STEP 7, perform hardware configuration (without attaching the HMI as a slave to the PROFIBUS bus, as the HMI is a secondary master), set the DP address and baud rate

Then, set the connection parameters in the touch screen programming software (note that the connection parameters should be consistent with those in STEP 7)

Finally, transfer the touch screen program to the touch screen via a download cable

After successful transmission, it indicates that the program has been successfully downloaded to the touch screen
