M262 Slow Online Edits when OPCUA Client is Connected

[louis87]

Hi There,

We are commissioning a control system utilising a M262 PLC and Ignition SCADA.

We have roughly 4,000 OPCUA tags that the ignition is subscribed to.

When we make an online edit to the PLC with the ignition SCADA connected, the online edit time blows out to ~3 minutes. It's pretty much unusable in this way..

When we disconnect the OPCUA client, the online edits are back to how they should be. 

We have tried other OPCUA clients with the same result. We even tried a blank project with 1 OPCUA tag, the edit time blew out to ~1min40sec.

Has anyone come across this problem before and know of a solution?

Regards,

Louis Pijpers.
