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
The External Signal Configuration: No error with the OPC server
Signal Mapping : No error with the OPC server
I have the same issue as "Kaak_BG". Everything connected but when i press the play button there is this Runtime Error.
Does anyone has a solution for this?
