OPC no values

[quintelosky]

Hi

I have a problem with opc client module. Rapidscada can connect to opc server, and read some values. I have a rapidscada connect to s7-1500 with opc server (open, no pass)

With siemens opc client .net I can read all values (db blocks,…) but in rapidscade I cant read values.

What I can do?

Many thanks

Hi,

I can help you if you provide remote support for the OPC server for testing. Is it possible?

[quintelosky]

Hi

It is impossible. Is a corporate lan. But, I do these tests in my house with two virtual machines: one running virtual plc (tia portal 15 + plc advance sim) and other running rapidscada (the screen is my personal pc). I can give you access to my computer and you can view the problem.

These is the sourcecode of the siemens opc ua .net client:

Many thanks. If you can repair these problem, rapidscada will be my scada for many projects with siemens s7-1200 and s7-1500

Hi,

Connecting to a computer by remote desktop (or similar tools) is a paid service.
I can help you for free if you open access to OPC server, so I can run OPC UA client on my computer to debug. To do this, you should configure port forwarding on a router.

Hi

Hi

Well, I continue firing with my lan. Now, I can connect in my lan to my plcsim from all computers, but I don’t know if a external pc can connect to my server opc ua.

I configured in my router: Port Forwarding (4840 to my plcsim ip), and dmz (to mi plcsim ip)

I sent you a pm with my public ip. I don’t know what hour is good for you, but I connect my computer now ( 16:52 gmt )

Thanks

EDIT: Upps, I can’t send a pm, my ip: 83.42.220.118

EDT2: Ok, I can connect to my opc server via other pc in other public ip. You can connect without problems

[quintelosky]

EDIT3: If you want, first you can connect with siemens opc ua server:
https://mega.nz/file/YRFiBByB#DLzKOsxGXZYNmbk7lUpq1D0_dRokkCObRP3pEmk6nAY
I used these program to check connection via internet and works fine, and you can view all blocks and values

Again. Sorry.
I’m doing some tests. I modified the file c:\scada\projects\myproject\instances\default\scadacomm\config\kpopcua_001.xml adding the nodes and I can read the values

  </Commands>
</KpOpcUa>

But the command don’t work, I can’t change values I think is a problem with dataType because kpopcua can’t add commands with other opc server simulator too (indicate datatype not recognized).

Can you check it?

Hello,
I can connect to opc.tcp://83.42.220.118:4840
I will check and write here

[quintelosky]

Ok

Now ( 6:05 gmt ), the opc ua server is running to the same ip ( opc.tcp://83.42.220.118:4840 ). I don’t shutdown the pc. If you will use the siemens opc ua client .net to verifiy the connection and blocks, run as administrator

Many thanks

[Mikhail]

Please try the update of KpOpcUa.dll

Fixes:
– browse nodes
– Int16 and Boolean types

String commands is currently not supported. It’s possible to support them.
Let me know about the results.

[quintelosky]

Ok. Now I’m working, when I return to my house I will check.

Can you try the commands and send values?

Many thanks

[quintelosky]

For example with:
“DB 16 Señales analogicas”.”TurbidezEntrada”.”MaxEscalat”
I need read the value and change the value, but datatype is float and yesterday I cant modify the vale
Thanks
