Ultralight Client User Experience

[marcel@realsolutions.nu]

Hello,

has anybody already played with the 3.14 'Ultralight Client User Experience' feature?

if configured as described in the help, the browser shows the screen to download the webclient plugin.... (no install should be necessary on the client)

I had expected that the defined panel should be shown in a certain window in the browser (because 'Ultralight Client User Experience' is based on VNC technology as described)...

BR, Marcel

Hello Marcel,

What is the url you are writing in the browser?
If you are just writing the url of the server it will try to download the plugin.
You should extend with /data/ulc/start.html
This should be described in the help.

Best wishes

Hi Lukas,

thanks for your quick reaction, and you're right: I had defined the startpanel in the config file, and only used the IP-adres in the URL.
(indeed described in the help)

just added ' /data/ulc/start.html ' and now it works, it's really great!!

Thanks,
Marcel

Hi Lukas,


when can we expect that this also works in the web-browsers on Android and iOS?

Hello,

for Android and iOS a native app is available for WinCC OA 3.14.
The apps are already available in the stores.

Please note that it is currently only a beta version.
The official version will be available in Q1/2016.

When the apps are available it will be announced officially. The announcement will also include information for a new demo project.

Best Regards

Hi!

I've tried connecting from Chrome, Internet Explorer as well as Firefox, without plugin.
It works nicely.

However, I can't get the iOS app to connect. It keeps showing the error "WCCILdata".

Is the app ready for this ULC UX yet?

Thank you.
Garry

ULC UX and the mobileUI app (iOS and Android) are not the same thing (although both are User Interface managers with the same look and feel of the panels).

To connect the mobileUI with your project, you need to have access to either
- the mxProxy manager (Multiplexing Proxy) when used
- or directly to data/event manager when not using mxProxy
meaning: the mobile device needs to be able to connect to the ports of the above mentioned managers.
You might need to open ports in a possibly running firewall.
Also check your config file if/which data/event entries it contains. Depending on your network, it might be so that
the config contains a hostname, which the mobile device (or better: the DNS server it uses) can not resolve.
In that case try to define IP Addresses instead of hostnames.

Hi Martin,

Thank you for the reply.
I am directly connecting without multiplexing proxy. The following is my config at server (Windows 8 running 3.14):

[general]
pvss_path = "C:/Siemens/Automation/WinCC_OA/3.14"
proj_path = "C:/WinCC_OA_Proj/KTP_Pertamina_v0"
proj_version = "3.14"
langs = "en_US.utf8"
pmonPort = 4999
data = "10.18.80.46:4897"
event = "10.18.80.46:4998"
mxProxy = "none"

Running netstat commands at the server returns shows the connection is "ESTABLISHED" on port 4897 for a short time, before the iOS app disconnects and the following is returned in the server log:

WARNING, 39, Connection lost, MAN: (SYS: 1 Ui -num 201 CONN: 1), Connection reset by peer (10054)

Could you help on this?

Thank you.

So you are worlking inside a local network. Is there a correctly configured DNS Server ?
If not, you probably see a failure in the log like "Connection to expired; did not receive any init message."
which happens when Data tries to make a reverse lookup of the client IP address but does not get an answer from DNS
(which we have seen in lokal networks with just a router which opens a DNS port but does not answer requests...).
Try adding the following config entry:

Code: Select all

[general]
noReverseLookup = 1

Hi Martin,

Yes, you are right. I got the log message "Connection from ::1 expired; did not receive any init message".
However, nothing has changed even though I have included the line noReverseLookup = 1 in the config entry.
The message still appears, and on the iOS device, it says "emergency / recovery mode".

I have the same problem despite testing this in multiple environments:

Case 1. Set up an independent wireless network that has no connection to internet, local connection only, with no other devices except server and iOS client.
Case 2. Instead of using my project, I used the GettingStarted project to test, and only modifying it by including the WCCOACtrl for webclient_http.ctl
Case 3. CentOS virtual machine

All three repeats the same error.

Kindly let me know if you have any ideas.
