How to configure OPC UA Server on EPC 1502 to collect data from AXC 3050

Dear all,

I come across with a problem with data exchange between EPC 1502 and AXC 3050.

Settings:

                                          * AXC 3050
                                          * No OPC UA Server
                                          * But OPC Datapoints
                                          * EPC 1502
                                          * OPC UA Server
                                          * Node Red
                                          * InfluxDB
                                          * Idea:

OPC UA Server on EPC 1502 will collect the all the variables which are declared as OPC on AXC 3050
* OPC UA Client in Node Red will request these data points and save into InfluxDB
* Question:
How to configure the OPC UA Server on EPC 1502 via PLCnext Engineer to refer AXC 3050 as data source?

Does anyone have experience with this?

Great thanks in advance!

I understand that you have also been in touch with the technical specialists in your local Phoenix Contact office, who are currently helping with this application.

Yeah. But your colleague suggested

                                          * via TCP (e.g.: Modbus TCP)
                                          * via Profinet (but he couldn't answer how to get the data into Node Red)
                                          * OPC UA Server under a Linux device

If I go for Option 3 such as a Raspberri Pi, then I don’t need EPC 1502 at all. I would think so.
Option 2 is not clear for me so far.
Option 1 requires Modbus Server configuration for AXC 3050.

So first, I would still ask whether it’s possible to carry out this OPC UA application

I will pass on this comment to your local technical support people.
I think the answer to this question …
So first, I would still ask whether it 's possible to carry out this OPC UA application… is “no” (sorry).
For the Profinet option, you could set up the AXC 3050 as a Profinet device, then use the EPC as a Profinet controller to collect the data from the AXC 3050. The EPC can copy that data to/from GDS port variables that have the “OPC” attribute selected, then if Node Red can act as an OPC UA client it could read and write the GDS port variables via the OPC UA server in the EPC.
