Did you tried running NX as an admin? Sometimes the communication between NX and the OPC Server is blocked by the windows firewall.

I have the same problem.

 

I have a Allenbradley  Controllogix Ethernet  PLC communication with Kepserver 6 running.

I have set NX MCD as administrator.

Still i can not get the communication between Kepserver and NX MCD running.

NX MCD is not seeing any OPC DA server.

Is there a manual how i can get this communication running.

Which NX Version are you currently running?

Try installing OPC Core Components V3.0++, restart NX and see if the issue is solved.

 

There's been a known issue between NX and older version of OPC Core components which could lead to the problem you described here.

I did choose in the External Signal Configuration: Kepware.KepserverEX.V6

I selected under in this window all the I/O

 

I have succesfully connected the I/O  in the signal mapping window

 

In the sequence editor i have connected this symbolic to the operations

 

so far so good.

 

But when i push the play button i get a Runtime Error window.

 

Object           Severity     Display Part                     Description

Unknown      Error          Strap_storage2_stp         Cannot connect to this OPC Server

 

Why ?

 

The External Signal Configuration:  No error with the OPC server

Signal Mapping : No error with the OPC server

Hello

Siemens Germany is at this moment testing my configuration.
I hope they find a solution.
17 july 2018 a new version of NX-MCD 1202 is coming available with OPC-UA support.
