In this view, the details test procedure about the OPC UA communication will be shown. The Siemens S7-1200 PLC V4.4 will be programmed by TIA Portal V16 to activate OPC UA Server function, while the UA Expert will be used as OPC UA Client

SIMATIC S7-1200 Firmware update V4.4:
OPC UA Clients – UaExpert v1.5.1

You are so calm. You speek to the point..no unnecessary talk. Covering all the points while teaching main point. 😊 Thank you so much for sucha an informative content🙏

[libanabu]

Awesome had some issue getting it done but watching your video over and over again like 300 times I was able to get it done. Big Thanks

[sergeykiparenko]

This video is big tressure. Thank you!

[Aman-ethr]

Very informative video. No hidden tricks! Thank you so much sir!

Hi! Beautifully explained. couldn't have been better.
Three request:
1)Could you also do the same with simulated PLC (Siemens plc advanced v2.0).
2)Can same thing also be achieved with nettoplcsim?
3)How to the repeat the process with ABB PLC?

Recommend to use the latest CPU firmware to do the test. Some wired problem may be caused by the firmware issue. e.g. V4.4.1 of S7-1200 fixed some issues on the OPC UA functions.
e.g. Update V4.4.1
The S7-1200 CPU firmware update V4.4.1 replaces the V4.4.0 and corrects the following issues:

-Corrects the number of allowed S7 routed connections with left-side modules
-When TIA downloads only hardware configuration, the OPC UA security policies are applied appropriately
-Corrects the OPC UA Structure sizes in OPC UA Binary Protocol
-Improves secure open user communication robustness
-Allows secure open user communication when using self-signed certificates
-Fixes sporadic DataLog corruption when downloading from the Web server

Great video about OPC UA.
I have a problem with Siemens OPC UA: currently using S7-1200 with firmware V4.4.1 and trying to transfer an array with 100 elements to my supervisory software.
But S7-1200 doesn't allow transfer entire array, only individual elements with individual NodeIDs. But with that many array elements the acquisition time goes beyond 800 ms and I need it to be under 100 ms.
Do you have an workaround in how to send an entire array data through OPC UA?

[logandematteis]

is there a way to set a custom nodeid ? because I have to set them at a specific identifier to use them on another program (and I can't set them as string because I use S71200 and it's not supported)

[nickiho]

Hi, could you show how the Sign&Encrypt and User administration be handled both on the PLC and the client side PC? Since if this is really deploy for a customer, they always want the full armor security, and ideally want an OPC-UA XML file exported for them for customer integration. Thanks!

[MMKurdia]

Thanks a lot for this great video, what is your Linkedin account ?

[alexvan]

hi for the 'simatic opc ua s7-1200 basic runtime license', is that required to purchase separately? my TIA didn't show up that option.

[HermanWillems]

I wanted to use the OPC UA server functionality. I wanted to test it. But you need an aditional license for the OPC UA server to work. WTF Siemens. :( i just wanna play around. Also does Siemens Provide OPC UA with TSN? (Time Sensitive Networking?) for hard real-time data transfer? (Like Profinet, ethercat can) Im afraid they just do the LEAST effort for OPC UA. Unlike other PLC brands. :( too bad.

[MrPrateek]

Thanks for a descriptive video but when I tried these steps my UAexpert could not connect to OPC UA server and gave "failed due to badtimeout" error. Anyone faced the same?

[jorgevarona]

Do you know how to write th value of a node to an other node in UAexpert?

[ashiqmumtaz]

How to access the data logs via OPC UA?

[pranavthakkar]

Is it not same as kepserver? Just wanted to know more about this.

[rahulravi]

I get BadTimeout and Bad_SecurityPolicyRejected when i try to connect in Uaexpert... please help me

[ShiqunQiguan]

Hi I'm using Raspberry Pi as a OPCUA Server, I have programmed the PLC control logic and cofigurated the variables supporting OPCUA features in CODESYS. However wenn I connect the OPCUA Client in UaExpert, I get following errors.

The server returned no certificate, all certificate checks will be skipped.
[uastack] OpcUa_P_RawSocket_InetAddr: getaddrinfo failed with 11001.
[uastack] OpcUa_P_ParseUrl: OpcUa_P_RawSocket_InetAddr reports error 0xA0060000.
Error ‘BadHostUnknown’ was returned during OpenSecureChannel.


Please help me out! Thank you
