Cannot access DataLayer in PLC Engineering

[Anonymous]

Hello,

In my XCD2 with RM21.07 I used access to Ethercat in PLC Engineering. However after the RM21.11 update, I cannot access it after login and it looks like this:

Additional question: What is the difference between DataLaterUser and DataLayerOwner (options for ethercat_master_instance)?

Kind regards,

Jacob

 The error looks like the cyclic data chosen in the project do not fit to the ones configured in the master. After update your EtherCat master need to be configured again.

DataLayerUser means that the PLC  is a client to the ctrlX Data Layer and uses the real time data provided by in this case the EtherCat master.
DataLayerOwner would be providing own real time data nodes to the ctrlX Data Layer that other clients can use. This feature is not implemented yet.

I can access the data in the data layer via the web interface. The problem only occurs when I try to access data layer from plc engineering.

Did you check that your PLC project is fitting to that data on the ctrlX Data Layer?

Turns out the reason was that I was using ctrlX PLC Engineering V1.10 and not V1.12. After a succesful update, deleting and readding the ethercat instance, it is working fine. Thank you for your assistance.
