Assistance with Connecting TIA Portal to GeoSCADA via OPC

[Mehdi_Sajjadi]

Hi,

I’ve been away from GeoSCADA for a while and recently started refreshing and upgrading my knowledge. I’m currently working on connecting the TIA Portal to GeoSCADA and have found that OPC UA appears to be the primary method for integration.

Within GeoSCADA, I’ve noticed there are four different types of OPC connections, and I’m unsure whether I should be using OPC UA or OPC Simple. Additionally, I’m unclear on how to properly define a "Server" and a "Scanner" in this context.

Could you provide some guidance on how to configure these components within GeoSCADA? Also, are there any considerations I should be aware of on the Kepware side?

Thanks in advance for your help.

Best regards,

Having the TIA Portal PLC (you haven't mentioned which PLC you're actually using) as an OPC-UA Server, and then having GeoSCADA Expert as the OPC-UA Client reading the tags from the PLC (Server) is the way that I would suggest here.

You would want to reference the help for creating OPC-UA Client connections.

Press F1 for help, max the window, look at the left hand tree for Driver Reference / OPC UA Driver.

Thanks BevanWeiss

I’ve mainly used Geo SCADA with DNP3, and I’m new to OPC. I’m trying to set up communication between Geo SCADA and a simulated S7-1511-1 PN PLC (via TIA Portal v19 and PLCSIM Advanced V6 connected to Kepware V6) but haven’t succeeded yet. I’m using the Geo SCADA trial (1000-tag) version and looking for a simple way to establish this connection for learning purposes

Thanks in advnace

It's all set now. I was initially confused between the different OPC UA options, but I've figured out that OPC Simple is the right one to use—and it's working perfectly

Appreciate it.
