OPC UA Certificates

[espenbo]

I have checked the link about OPC UA certificates:

OPC UA & CODESYS | Webinar | English

However, I keep getting error messages when trying to generate them.

I have verified that the clock is correctly set on the device.
I have tried generating the certificates while being connected to the device and while being disconnected.
I have flashed the CC100 PLC with new firmware 04.06.03(28), but the issue persists.

Is anyone else able to generate OPC UA certificates on the CC100?

Hello espenbo,
i would set the controller to Stop when creating the certificates. Depending on how busy your controller is, the certificate creation in Run may not work.

I have set the PLC to stop and tride to generate certificate

Did not help

[espenbo]

Yes:)
I restored the plc from a SD card and tried one more time

from the 750-8xxx pdf
OPC UA Server
750-8xxx
Version 1.1.0, FW Version 03.06.09(18), OPC UA Server Version 1.2.5

I’m trying to install a new certificate with UAexpert on my wago cc100

I have connected the pls with uaexpert and have connection.

But when I do as the manual said

I ask on the discord server NFEA OPC UA
And they said look in serverProfileArray to see if GDS is supported

I can’t find anything about GDS. Is GDS push supported on CC100?

Is GDS push supported on PFC100, PFC200, PFC300?

Hello espenbo,

GDS push only works with e!COCKPIT based firmware and the WAGO OPC UA Server. The CODESYS OPC UA Server doesn´t yet support this function. According to the CODESYS RoadMap, the function will be implemented with V3.5 SP22 (2026).
