OPCUA Datasource setup in codesys Error in OPC UA call BadCommunicationError

Hi all,
I am trying to Configure a Datasource in Codesys 3.5 SP 19 Patch 7. I am able to connect and browse through a OPC UA server during initial configuration. But the minute I download to the PLC. I see a bunch of errors.

You need to update the PLC version (29) and put a new version of Codesys (Codesys V3.5 SP21 PATCH 1).
There will be no problem.

Hello thomas, beware the customer is using a EC300 (752-8303/8000-0002) and the FW 29 is only for PFC100 and PFC200, the FW for other device will only be available around September …

Hi, Can you confirm if PFC300 is also supported?

Hello PFC300 will also be supported for 3.5.21.10 or higher in September (unfortunately not with the current release).
