Hello,

i set up a simple codesys project with some global variables. i created a symbol configuration and send it to the plcnext.

With the uaexpert i can connect without any problem, but there are no variables to read. Only the server statistics available.

Who is hiding my variables. Any idea?

Hi Alex,

I am afraid that you will need to contact Codesys for support with their runtime. I don't think they use the Phoenix Contact OPC UA server with their runtime, and if this is the case then you won't see any variables on our OPC UA server.

We have no insight into the workings of the Codesys runtime, so Codesys are the best people to support their app.

Hi Martin,

how can i identify the Phoenix Contact OPC UA server? The value in path Root.Objects.DeviceSet.SXC F 2152.Manufacturer is ("en", "Phoenix Contact")  SoftwareRevision 2019.0.4 LTS (19.0.4.22338 ).

Hi Alex,

It looks like you are connecting to our OPC UA server. By default, our OPC UA server runs on port 4840. The Codesys installation has probably not disabled or re-configured our OPC UA server. If Codesys installs their own OPC UA server, it may be listening on a different port. You will need to check this with Codesys.

Problem Solved:

@Phoenix Contact Support just Notice that the minimum Version for Codesys is

2019.6 or higher.

After the firmware update, all running fine.
