According to the TCP/IP protocol, is not the same network segment of course, can not pass normally.
So in the process of PLC and touch screen, you must set up the PLC and touch screen, computer, three devices IP are in the same network segment, and can not be re-IP.
I. Configuration PC and touch screen through the RS485/422 interface to connect.
1. Turn off the HMI device.
2. Connect the RS485/422 connector of the PC/PPI cable to the HMI device.
3. Connect the RS232 connector of the PC/PPI cable to the configuration PC
2. Configure the PC/PPI cable.
Users who use the PC/PPI cable to connect the HMI device and the configuration PC need to use the DIP switch to set the transmission rate.
III. Users can set the following bit rates.
D. Connect the configuration PC to the Smart?Panel through the Ethernet interface.
