I now want to use 4PPC80_156B10B to display the mappview screen of the program in X20CP3586. I connected the Ethernet of both and configured it, but the screen shows that access is refused [{C432B30C-B38F-4915-B39A-31BF285BC27B}]

Hi, That’s a good start. Unfortunately, there are still many possibilities. Next, I would try to program a visualisation on the C80 itself and display it via ETHInternal. I would also activate the option ‘Ignore server certificate errors’ in Terminal configuration ->Web . And I think the issue o…

Hello, if I understand you correctly, you want to display the visualisation of your own PLC and not that of the c80 system. The ETHinternal is only intended for communication between the terminal and the built-in controller. This means that if you really want to display the visualisation of the X2…

Hi Alexander, Thank you for your answering! So How should I configure the ETH? For example, now the IP of the X20CP is 192.168.1.88, so I could get the mappview visualisation on 192.168.1.88:81. This is the ETH I configured On the PPC80, but it seems not work well. [{328515AA-92F8-40EB-9B40-236…

I’m just asking out of interest, but why are you using a C80(Controller) and not for example a T80(Terminal) for this task of displaying the visualisation of a PLC?

Hi Alexander, Thanks for your answering! Yeah, I just test because one customer want to do that. I just configured as the photo, but it still can not be shown in the C80 . [{0086E04C-582F-42C2-8555-8534FC1051C2}] [{C882C15B-9E72-4550-9D71-408B0736B49A}] [{AAA2411F-442D-4411-AC09-34FC0AAFD380…

Yeah, I have show the mappview on the C80 successfully. Thanks for your help!!
