Siemens S7/TIA v18: Logging of Data...

[Mas01]

Edit: Could it be firewall issue? But that wouldn't make sense to me, because how else would I be able to compile code etc?
Edit: I can ping the IP address and that's fine too.

On your device configuration check the following settings under profinet interface:
-Ethernet addresses: Tick the box for "use router" and put in the router IP
-Web server access: Tick the box to enable web server

I seem to remember having an issue with accessing the web server without the router IP setting.

This first one in bold...on mine it was UNticked, so I ticked it. It auto-filled with 192.168.0.1, appeared in pink suggesting it was a bad value, for some reason (?)

The second one was already ticked.

Did a save, went back online, but still can't see the webpage when I enter https://192.168.0.1.

Many thanks for trying to help me. Appreciate it.
Cheers

EDIT: The only "router" in my system (if router is the right word for it) is a SCALANCE XB005 ...thus far, I've only ever called it a "switch". It connects to the PLC, HMI, and development Laptop.
Would this SCALANCE box have its own IP?

I've accessed the web page without the router option being ticked. When you download web page related stuff, there is an extra check box you need to tick for the web applications - I've not got a real plc to test this but I'm sure a tick box is shown when downloading to a real plc.


Edit: I might be confusing the check box requirement, and that you need to check it when you have a ViewOfThings application.

that scalance box is unmanaged, which means it has no IP.

A router bridges two different subnets and lets traffic move between them. From the automation layer this seems super trivial, but from a traditional networking perspective it's apparently a big deal.

What is the IP of your laptop you're using to try to access the webpage? If it's in the 192.168.0.X subnet, you don't need a router.


Make sure you're using the https:// before the IP. http:// is disallowed according to your settings (the default).

I'm not sure what the IP address of the development laptop is.
Here's what I get went I type "ipconfig" at the command prompt (see pic).

Would one of these be the IP of the laptop?

I think the expression is "Clutching at straws" LOL

Do I need to set this up, by any chance?

It is not the user-defined pages.
With the webserver enabled and a user configured you should be able to open a standard webpage.

It could be your PC or the webbrowser.
Try another PC, try chrome, firefox.

[Puddle]

I think I gave bad advice there by assuming (incorrectly!) that you were connected to a wider network. The value for router address is the default gateway from the command prompt.

User defined pages is for things like HTML pages, I have a few configured to show tables of information to allow people to see relevant data.

Sounds like it should be working. You could try unticking the https box in case the browser is deciding to remove the prefix for some reason.

Also, when you get it going it will most likely show a security warning rather than loading straight up.

I noticed on the website user administration section you created an admin user with a password, but it still had minimum permissions. It shouldn't prevent you from even getting to the web page in the first place, but it might mean you can't do anything once you get there. Try checking all the permission boxes for Admin, at least for now.



I'd say at least a third of the time my PLC isn't doing what I want, it's because I either forgot to DL or did a SW only DL (no HW) or didn't notice that the DL never actually happened because of a sneaky compile error. try to do a full download again, just to check.

[Mas01]

@puddle, no worries mate...the PLC is not networked, no router. It just sits on my desk, connected to the HMI and development laptop.

@jesperMP and @mk42... I'm back home so I'll try out your suggestions first thing tomorrow. Dunno what I'd do without the help on this forum... and I'm meant to be the company PLC "expert" LOL.

[Mas01]

I've tried Chrome, Firefox & Microsoft Edge - all of them are unable to reach 192.168.0.1

Does it matter if PLC is in RUN mode or STOP mode?

[Mas01]

UPDATE: I connected the ethernet cable to another computer, but I still can't access 192.168.0.1.

I will keep investigating this. It's so frustrating!

Have you tried it with WiFi disabled?
Failing that, see if another IP address works.
