Can I use the CP5512 card to communicate with the touch screen?
The CP5512 card supports MPI / PROFIBUS / PPI / FWL communication protocols. Required accessories: MPI cable 6ES7901-0BF00-0AA0 Note that the baud rate must be the same as the baud rate of the MPI port of the HMI to be communicated. It is possible that the baud rate of the PLC you are connected to is not the same as the baud rate set by the HMI, so it cannot be connected. There is also no need to open the PLC and HMI at the same time. Please close the PLC software before connecting the HMI.
