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}](https://europe1.discourse-cdn.com/brcommunity/original/2X/e/e1b5934c0e8239f44ec86be67666348e3dc21cbb.png) ---

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 X20CP, you would have to set up a network between the ETH(IF2) of the C80 and the ETH of the X20CP. Both require an IP address in the same network. Then you can configure the address of the X20CP for the terminal. If the visualisation is implemented on the C80, Ethinternal would be the right choice. I hope this helps. Best regards, Alex ---

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-9B40-236752ED802A}](https://europe1.discourse-cdn.com/brcommunity/original/2X/3/30189363ff610edc56d1261113666bfd0cfb0321.png) ![{282CB76F-D956-489A-9932-EEB3E92FF924}](https://europe1.discourse-cdn.com/brcommunity/original/2X/3/37ec5fac41c25face60582a095efb80dc54cd645.png) ![{2A3BEE3A-98AF-46E6-A8FF-FC86D1C9A538}](https://europe1.discourse-cdn.com/brcommunity/original/2X/3/3263c2f5cc1e5f5bec3dced348fe54d72eed96d1.png) ---

I’m just asking out of interest, but why are you using a C80( **C** ontroller) and not for example a T80(Terminal) for this task of displaying the visualisation of a PLC? But if it’s just for a test, it can also be set up as desired. Leave the internal ETH set to default. We don’t need it. That’s right, you can set the ETH interface of the C80 as you have already done. Set the ETH interface of the CPU in the same range, e.g. 192.168.1.88, correct, only the last digit must be different. The subnet mask fits with 255.255.255.0 for both devices. The URL of the C80 terminal depends on the visualisation settings. e.g. [http://192.168.1.88:81/index.html?visuId=yourVisuName](http://192.168.1.88:81/index.html?visuId=yourVisuName) See–\> > **[B&R Online Help](https://help.br-automation.com/#/en/4/visualization/mappview/guides/getting_started/getting_started_testvisu.html)** ---

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}](https://europe1.discourse-cdn.com/brcommunity/original/2X/b/b7f0bc4643b336adce79616a2e9e34688321f23a.png) ![{C882C15B-9E72-4550-9D71-408B0736B49A}](https://europe1.discourse-cdn.com/brcommunity/original/2X/4/4f3bf15004b3b262779ff9873291998d4eb7d42e.png) ![{AAA2411F-442D-4411-AC09-34FC0AAFD380}](https://europe1.discourse-cdn.com/brcommunity/original/2X/c/c4d42518952daba5891a83ec4e05d2d097af51de.png) ![{34F85691-A981-4EAF-B60A-4D84C2553FAC}](https://europe1.discourse-cdn.com/brcommunity/original/2X/5/5758953c1a78149af7174831c006457ba589eda3.png) ![{B6C1BC07-CBEB-4B32-9B8E-A478E2B9AA08}](https://europe1.discourse-cdn.com/brcommunity/original/2X/a/ab29c427e0d792a32073babb0aff8d8767b8477f.png) ---

Have you attempted to display the visualisation in your browser (Edge or Chrome) on your Windows PC? The PC’s IP address must also be correct, of course.

Hi Alexander Yeah， I can show the mappview page in my PC at 192.168.1.88:81 But， when I used the C80, the page is white. ![{E43C5381-D217-44B0-945F-1B83689D9A74}](https://europe1.discourse-cdn.com/brcommunity/original/2X/f/f398c5681ba7ffda2b4e82a391c20be922d76bc2.jpeg) ![{8AF0017C-72EE-4F80-B96D-3951AE9B5696}](https://europe1.discourse-cdn.com/brcommunity/original/2X/c/cee152edcbc8a8c0241fef77210ce70d98136034.jpeg) ---

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](https://help.br-automation.com/#/en/4/hardware/powerpanel_c80/web.html). And I think the issue of NAT configuration is your problem, see [NAT configuration](https://help.br-automation.com/#/en/4/hardware/powerpanel_c80/nat_configuration.html) I hope that helps.

Did you check the PLC logger if there is something that points to an error? Stephan ---

Hi Alexander, Yeah, I just follow your advise to enable the Source NAT, then it works! ---

Hi, I am trying the same thing for a customer, but can’t seem to make this work. Did you use the default NAT settings or did you change some settings their to make it work? Kurt
