Setting up the OPC UA Server on S7-1500 PLC using TIA Portal and Basic Diagnostics with UA Expert

[@hemanthkumar-xf8ki]

OPC UA cert and GDA are interesting to explore. Appreciate a video on the same. Happy to collaborate.

[@mohamadismailbasha6083]

Thank you for all the hard work you put into the video

[@AutomationStation]

My pleasure!

[@AleksandarBelkoski]

Oh my GOD! this is exactly what i needed. Great explanation and its even in English. Thank you!

[@Mrscuppacoffee]

Thank you so much, using this I've finally managed to connect to the industrial databridge

With siemens PLC (S7-1200 or S7-1500), is there is any limit to how many no. of tags are accessible by the clients? Also, how many no.of OPC client can make simultaneous connection with the OPCUA server? For example, with ABB PLC PM-5032, there is a limitation of no. of tags accessible via OPCUA which is 125 tags. Also, only 5 clients can make simultaneous connections with the OPC servers

Can you give me the Version of TIA PORTAL used here? I'm currently on V15.1 and the server interface doesn't appear like yours.

Hello Sir, how can we connect OPC UA with UA Expert and simulate process simulation(virtual equipment)?

[@Sh_Firouz]

Thank you so much

How can I add server interface manually in OPC UA communication ? In my case import server interface option is showing rather than add server interface.

[@Braj_Kumar]

Whenever I create a Server interface in TIA Portal for OPC UA communication, after adding a tag to the Server interface and compiling it, I encounter the message 'Totally integrated automation portal has encountered a problem and needs to be closed.' and the application shuts down. What could be the problem?

Uninstall the latest windows update

[@ishouldbeonmountrushmore8156]

add new server doesn't open that window for me after following all the steps. it always open a greyed out window

[@NajeemShaik]

Under PLC_1, i do not have the folder of "DataBlockGlobal", or any folder for that matter Please let me know how i can fix this Thank you

[@jakubskorcz5933]

Hi, I have S7-1200 1214CPU with firmware V4.5 and I don't have the "standard simatic interface" option in the properties. Do you maybe know why?

[@AutomationStation]

Yup, that's only available as an option on the S7-1500. On the S7-1200 you need to create your own custom server interface and define variables you'd like to expose.

[@adnanjayousi9140]

Thanks for the clear video, is it possible to toggle values using the OPC UA also ? and not only reading the tags of the PLC ?

[@AutomationStation]

Yes that's possible

[@ramimedkour7233]

i have problem in UaExpert [bad-timeout]

[@abdullahaldoghim8010]

Thanks for the helpful video. What does "max. number of registered nodes" by configuration under options means?

[@AutomationStation]

Max number of monitored elements

[@abdullahaldoghim8010]

@@AutomationStation Sorry for asking again. What effect have the monitored elements? As i know the monitored items are to observe how many single variable will be monitored, right?

[@rezamagham4495]

Good please instruct about python with opc

[@engineeringart8502]

Thank you for this video! Does the 1500 work as a Client as well?

[@AutomationStation]

Yup, with the new firmware it does

[@d.militomilito2002]

Thank you very much, i appreciate your tremendous effort! i would to like to know a 1500 as a client and also with Kepserver and 1500 how to communicate with security (256ha256) because i can't connect when i choose security settings in the kepserver but without security, i can, i don't know why...

[@AutomationStation]

I have not attempted this configuration before, but I would presume that you must take the certificate from the Kepware OPC UA Server and add it to the TIA Portal project.

[@luisangelht6933]

I have the same problem, I can't connect my S7-1500 using that kind of security (256ha256), I tried everything and I am not able to stablish the communication between my PLC and the server Was you able to fix the problem?
